Izravnava stroja

1

Nastavite višino stroja:

X- in Y-os premaknite na referenčno pozicijo.

Razrahljajte sredinska izravnalna vijaka [2 and 5] in s tem zagotovite, da ne podpirajo nobene teže.

Stroj na 4 kotne izravnalne vijake namestite 3" (76,2 mm) nad tlemi.

2

Približna izravnava stroja:

Izravnalni vijak št. 4 obrnite navzgor.

Čez linearne vodnike na X-osi postavite granit blizu nosilca ležajev krogličnega navojnega vretena na X-osi.

Nivo strojnice postavite na granit vzporedno z X-osjo. [1]

Prilagodite izravnalni vijak št. 6, dokler stroj ni izravnan na X-osi.

Nivo strojnice postavite na granit pravokotno na X-os. [2]

Prilagodite izravnalni vijak št. 3, dokler stroj ni izravnan na Y-osi.

Izravnalni vijak št. 4 obrnite navzdol, dokler ne pride v stik z izravnalno blazinico.

Prilagodite obračanje X-osi:

Sestavite T-2192 s T-2181.

Y-os premaknite na sredino gibanja.

T-2192 postavite na stran vretena.

Prepričajte se, da je libela na T-2181 dovolj blizu, da je z nje mogoče odčitati vrednost.

Če ni, razrahljajte vijak, s katerim je T-2192 pritrjen na magnetno osnovo, in po potrebi premaknite adapter.

X-os potegnite na stran in izmerite obračanje X-osi. Odčitajte vrednosti na referenčni poziciji, na sredini in na koncu gibnja X-osi.

Prilagodite izravnalni vijak št. 4, če med odčitkom na referenčni poziciji in odčitkom na koncu gibanja ni odstopanja.

Opomba: Pri tem NI treba, da se libela na T-2181 nahaja na sredini viale. Biti mora le dovolj blizu, da je z nje mogoče odčitati vrednost.

4

Nastavite srednje izravnalne vijake:

Srednje izravnalne vijake obrnite navzdol, dokler niso v stiku z izravnalnimi blazinicami, nato pa jih zavrtite še za 45 stopinj.

Preverite obračanje X-osi. Prilagodite srednje izravnalne vijake, da popravite obračanje X-osi.

How to identify the Multi-Piece and the Unibody trunnion   

1) Multi-Piece trunnion:    UMC machines built approximetely before 11/2022 will have this configuration.

2) Unibody trunnion:    UMC machines built approximetely after 11/2022 will have this configuration.

1

Remove the A-frame trunnion support:

Remove the bolts [1] that secure the A-frame trunnion support [2] to the base and take out the shims between A-frame support and the base.

Rotate the A-frame support [2] counter-clockwise to clear the edge of the base [3].

Pull the A-frame support off the bearings.

 Note: The A-frame support might vacuum lock on the bearings. Use the zip-tie to pry the seal [4] open.

 Caution: To lift the trunnion support, get the aid of another person. The support weighs 85 lbs (39 kg).

2

Measure the B- axis of rotation parallelism to the Y-Z plane:

For a machine with a Classic Haas Control, change Parameter 151:20 (B axis CHK TRAVL LIM) to 0.

For a machine with a Next Generation Control, change Parameter 6.021 (B axis CHK TRAVL LIM) to FALSE.

Measure the parallelism of the platter to the Y-Z plane with the B axis at 90° and then the B axis at -90° as shown in the picture.

Position the Y-Axis in the following starting position:

UMC-500: Y=0, Sweep 15”, 3rd T-Slot Land from the top.

UMC-750/1500-Duo: Y=-1.0, Sweep 18", 3rd T-Slot Land from the Top .

UMC-1250: Y=-1.0, Sweep 28", 3rd T-Slot Land from the Top.

UMC-500PP: Y=-4.0, Sweep 7".

UMC-750PP: Y=-2”, Sweep 15".

UMC-1000PP: Y=-4”, Sweep 15".

Compare the results at B 90° and B-90°. The results should be...

  • Symmetric against the Y-Z plane, positive or negative direction
  • Less than 0.0010"/20"

If the results are symmetric against Y-Z plane, and are less than 0.0010"/20 inches: Go to Step 5.

If the results are symmetric against Y-Z plane, but are more than 0.0010"/20 inches: Go to Step 4.

 Warning: If the results [3] are not symmetric against the Y-Z plane, the B axis rotary needs to be aligned: Go to Step 3.

3

Align the B axis of rotation parallel to the Y-Z plane:

Loosen the (6) bolts [1] that secure the B axis rotary to the base casting.

 Note: Keep the bolts sufficiently snug to control the adjustments.

Adjust the front and rear setscrews [2] until the measurements taken in Step 2 are symmetric against the Y-Z plane.

Torque the (6) bolts [1]. Refer to Haas Fastener Torque Specification.

Verify the measurements in Step 2 after the bolts have been torqued.

4

Align the C Axis of rotation perpendicular to the B Axis of rotation:

Remove the bottom C-Axis access cover.

Loosen the (12) bolts [1] that hold the C Axis body to the B Axis platter face.

Reach the bottom (4) bolts through the C Axis access port.

If the B Axis is symmetric in the positive direction [4], install horseshoe shims [2] of appropriate size behind the top (2) bolts.

If the B Axis is symmetric in the negative direction [5], install horseshoe shims [2] of appropriate size behind the bottom (2) bolts.

Torque the (12) bolts to 80 Ft-lbs (108 Nm).

Cut the excessive shim material off.

Verify the measurements in Step 2 after bolts are torqued.

5

Align the trunnion support shaft co-axial with the B Axis of rotation:

Setup (2) indicators on the outer race of the trunnion support bearing [2] as shown in the picture.

Mark the spot on the outer race where one of the indicator needles is contacting the surface.

After moving the B Axis to 90° or -90° you will align the marked spot with the needle again to exclude the bearing runout error from the measurements.

Take the readings when B is at 90° and B at -90°. Compare the readings. 

 Caution: The B axis brake needs to be clamped when taking the readings.

The deviation between the results when B is at 90° and at -90° needs to be less than 0.001" on each indicator.

 Note: The indicator on the side of the bearing will measure top to bottom alignment and the indicator on the top of the bearing will measure side to side alignment.

____

For models with a multi-piece trunnion

Loosen the (6) bolts [3] on the C Axis body support. Keep the bolts sufficiently snug to control adjustment.

Adjust the (8) set screws [4] until deviation between B at 90° and B at -90° is within 0.001".

Torque the (6) bolts [2] on the C Axis body support to 80 Ft-lbs (108 Nm).

Verify the alignment after the bolts have been torqued.

____

For models with a unibody trunnion

Jog rotary to B90. Set up an indicator on the highlighted surface as shown in the lower diagram .

Rotate B-axis 180 degrees (90 to -90).

Run out (NTE 0.010” TIR).

 Caution: If the measurement exceeds the tolerance then contact support.

6

Install and shim the A-frame trunnion support:

Move the B Axis to 90°.

Setup an indicator [1] against a machined surface of the C Axis body. Set the indicator to 0.

Use plastic zip ties [2] to pry the seal open while installing the A-frame support. This lets unwanted air and grease out of the assembly.

Install the A-frame trunnion support [3] over the bearings.

Remove the cable ties.

Turn the trunnion support clockwise until it is vertical.

 Note: The weight of the A-frame support will cause the trunnion to sag. The amount of sag is measured with the indicator that was previously setup on the side of the C Axis body.

____

For multi-piece trunnions

Adjust the shims [4] between the A-frame support and the base casting to remove the sag until indicator reads 0 again.

When the indicator reading is 0, torque the (4) bolts. Refer to Haas Fastener Torque Specification.

Verify the reading after bolts are torqued. Adjust the shims again if necessary until the indicator reads 0.

____

For models with unibody trunnion

Determine the amount of shim stock [4] needed to raise the Trunnion arm so the indicator reads 0.005".

The indicator [1] value will change once the support is torqued.

With indicator still in place:

  • Torque trunnion support bolts to appropriate values.
  • Check indicator to make sure it reads between the range of

Trunnion arm raised (0.005” to  0.010”).

 Note: For unibody trunnions, the shim location may also be used to correct the C-axis to X-Y plane perpendicularity instead of shimming the saddle trucks.

 Caution: Use equal amount of shims on each side of the A-frame support. Unequal shims will cause the A-frame support to pull the trunnion to the side.

Verify the B Axis of rotation alignment to the Y-Z plane (Step 2). Loosen the bolts and tap the A-frame support side to side if necessary to correct the B axis to Y-Z plane alignment.

7

Set C-axis perpendicular to X/Y plane:

Move the axes to

UMC-750's........X= -10.5" & Y=0."

UMC-1000's......X=-17.0" & Y=-0."

Zero an indicator [1], on a Ground Block [2], 1/2" off the edge at the rear of the platter (Mag-Base on Spindle), with C at 0 Degrees

Rotate C-Axis to 180°.

Move Y axis, and ground block, in Y Axis negative direction until you are 1/2" away from platter edge, and take the perpendicularity measurement

Adjust the shims until the average error is within 0.0005" end to end.

 Note: For unibody trunnions, the shim location under the bearing support may also be used to correct the C-axis to X-Y plane perpendicularity instead of shimming the saddle truck.

Caution: Shim either two front trucks or two rear trucks with the equal shim.

Note: Shim one truck at the time to maintain the X to Y squareness.

Verify the measurements after all bolts are torqued.

Verify the X to Y alignment in Step 2.

9

Check C-axis perpendicularity to X/Y plane:

Align the indicator centered over the C-axis bore with the Y-axis at -10.

Jog positive in the Y-axis and align the indicator over the center of the last section of the platter and make a mark at this spot with a washable marker.

Insert 1-2-3 block as shown and set the indicator to zero.

Remove the block and rotate the platter 90 degrees, following the marked spot with the indicator.

Insert block back between the indicator and platter. Note reading.

Repeat the previous two steps, taking readings with the platter at 180, 270 and 360 degrees.

Multi-piece trunnion:  (NTE 0.0005")

Pregled

Pred odpravljanjem težav z natančnostjo ali geometrijo na UMC-750 mora tehnik podrobno razumeti naslednje osnove:

Težavo z geometrijo ali natančnostjo stroja UMC-750 je treba obravnavati sistematično in v pravilnem zaporedju. Naslednje informacije je treba dosledno upoštevati in to v ustreznem zaporedju.

Ključnega pomena je, da je bil stroj pred kakršno koli oceno ali prilagoditvijo geometrije stroja preverjen glede pravilne ravni in poravnave vrtljivih osi s strojem

Številne napake so lahko vzrok za trk stroja ali težave bodisi z orodnimi aplikacijami bodisi s programiranjem. Ne poskušajte spremeniti geometrije stroja, brez da bi preverili splošno raven in geometrijo stroja v skladu s Poročilom o pregledu. To vključuje preverjanje Machine Rotary Zero Point (MRZP).

V primeru trka so na stroju 4 drsni spoji. Ta območja so glava vretena do podstavka, od podstavka do sedla, sedlo do mostu in trunion do opore truniona.

 Opomba: nobenega od teh spojev ne smete nikoli podlagati s podložnim lističem. Trk stroja nikoli ne sme spremeniti števila podložnih lističev, ki so zahtevani v stroju po tovarniških nastavitvah.

Dobro si je zapomniti, da je linearna natančnost stroja 0,0004/10" in kotna natančnost +/- 15 arc-sec. Te tolerance se lahko hitro seštevajo.

Temeljito je treba preveriti, ali je obdelovalna aplikacija smiselna in v okviru zmogljivosti vpenjanja in orodja stroja.

Ocenite stanje stroja

Ugotovite, ali se je v stroju že primeril trk. Preglejte zgodovino alarmov; poiščite fizične poškodbe ploščatega jekla, mize, glave vretena itd. Ne glede na to, kako "neznaten" je bil trk, bo to vplivalo na geometrijo stroja. Če je v stroju prišlo do trka, je treba opraviti popoln pregled geometrije stroja

Ocenite splošno stanje vpenjanja kosov in stanje orodja za rezkanje.

Pridobite popolno varnostno kopijo stroja in poročilo o napaki.

Preverite nivo in geometrijo stroja

Preverite, ali je stroj izravnan in ali je rotacijska os poravnana s strojem

 Opomba: zdaj še ne poskušajte prilagoditi geometrije stroja, razen nastavitve nog za izravnavo.

Če stroj ni v izravnan ali rotacijski element ni poravnan, ponastavite izravnavo in poravnajte rotacijski element.

Opravite celoten pregled geometrije, pri čemer za vsako os preverite vrsto in smer morebitnih napak.

Analizirajte poročilo o pregledu.

Če kateri koli od odsekov poročila o pregledu ni v okviru tolerance, je treba stroj ponovno poravnati.

Preglejte aplikacijo

Zberite naslednje podatke o obdelovancu, vpenjanju obdelovanca in orodju:

  • Katere lastnosti niso v okviru tolerance, obseg in smer napake
  • Ali je obdelovanec strojno obdelan s pomočjo 5-osnega, 3+2-osnega ali 3-osnega stroja?
  • Preglejte obdelovanec in pristop k strojni obdelavi
  • Ali je mogoče katero koli napako v natančnosti kosa zmanjšati s spremembo načina strojne obdelave?
  • Ali so težave prihaja zaradi ponovljivosti, velikosti ali geometrijske težave?
  • Ali program uporablja TCPC ali DWO?
  • Ali v tabelah za kompenzacijo dolžine obstajajo kakšne vrednosti?

8.6 Uravnavanje sečišča B/C osi - Poravnava

Uvod

Ta postopek vam pokaže, kako izmeriti in poravnati sečišče B- in C-osi.  Preden poskusite s tem postopkom, preverite, ali je stroj poravnan s poravnavo UMC-750.

Zatem morate poravnati B- in C-osi po tem, ko:

5-osna razdalja rotacijskega centra določa razliko med rotacijskimi centri vrtenja: Rotacijske ničelne točke stroja (MRZP) C-osi in MRZP B-osi v X-osi.

Možno je, da med MRZP C-osi in B-osi ni razlike.

How to identify the Multi-Piece and the Unibody trunnion   

1) Multi-Piece trunnion:    UMC machines built approximetely before 11/2022 will have this configuration.

2) Unibody trunnion:    UMC machines built approximetely after 11/2022 will have this configuration.

1

Remove the A-frame trunnion support:

Remove the bolts [1] that secure the A-frame trunnion support [2] to the base and take out the shims between A-frame support and the base.

Rotate the A-frame support [2] counter-clockwise to clear the edge of the base [3].

Pull the A-frame support off the bearings.

 Note: The A-frame support might vacuum lock on the bearings. Use the zip-tie to pry the seal [4] open.

 Caution: To lift the trunnion support, get the aid of another person. The support weighs 85 lbs (39 kg).

2

Measure the B- axis of rotation parallelism to the Y-Z plane:

For a machine with a Classic Haas Control, change Parameter 151:20 (B axis CHK TRAVL LIM) to 0.

For a machine with a Next Generation Control, change Parameter 6.021 (B axis CHK TRAVL LIM) to FALSE.

Measure the parallelism of the platter to the Y-Z plane with the B axis at 90° and then the B axis at -90° as shown in the picture.

Position the Y-Axis in the following starting position:

UMC-500: Y=0, Sweep 15”, 3rd T-Slot Land from the top.

UMC-750/1500-Duo: Y=-1.0, Sweep 18", 3rd T-Slot Land from the Top .

UMC-1250: Y=-1.0, Sweep 28", 3rd T-Slot Land from the Top.

UMC-500PP: Y=-4.0, Sweep 7".

UMC-750PP: Y=-2”, Sweep 15".

UMC-1000PP: Y=-4”, Sweep 15".

Compare the results at B 90° and B-90°. The results should be...

  • Symmetric against the Y-Z plane, positive or negative direction
  • Less than 0.0010"/20"

If the results are symmetric against Y-Z plane, and are less than 0.0010"/20 inches: Go to Step 5.

If the results are symmetric against Y-Z plane, but are more than 0.0010"/20 inches: Go to Step 4.

 Warning: If the results [3] are not symmetric against the Y-Z plane, the B axis rotary needs to be aligned: Go to Step 3.

3

Align the B axis of rotation parallel to the Y-Z plane:

Loosen the (6) bolts [1] that secure the B axis rotary to the base casting.

 Note: Keep the bolts sufficiently snug to control the adjustments.

Adjust the front and rear setscrews [2] until the measurements taken in Step 2 are symmetric against the Y-Z plane.

Torque the (6) bolts [1]. Refer to Haas Fastener Torque Specification.

Verify the measurements in Step 2 after the bolts have been torqued.

4

Align the C Axis of rotation perpendicular to the B Axis of rotation:

Remove the bottom C-Axis access cover.

Loosen the (12) bolts [1] that hold the C Axis body to the B Axis platter face.

Reach the bottom (4) bolts through the C Axis access port.

If the B Axis is symmetric in the positive direction [4], install horseshoe shims [2] of appropriate size behind the top (2) bolts.

If the B Axis is symmetric in the negative direction [5], install horseshoe shims [2] of appropriate size behind the bottom (2) bolts.

Torque the (12) bolts to 80 Ft-lbs (108 Nm).

Cut the excessive shim material off.

Verify the measurements in Step 2 after bolts are torqued.

5

Align the trunnion support shaft co-axial with the B Axis of rotation:

Setup (2) indicators on the outer race of the trunnion support bearing [2] as shown in the picture.

Mark the spot on the outer race where one of the indicator needles is contacting the surface.

After moving the B Axis to 90° or -90° you will align the marked spot with the needle again to exclude the bearing runout error from the measurements.

Take the readings when B is at 90° and B at -90°. Compare the readings. 

 Caution: The B axis brake needs to be clamped when taking the readings.

The deviation between the results when B is at 90° and at -90° needs to be less than 0.001" on each indicator.

 Note: The indicator on the side of the bearing will measure top to bottom alignment and the indicator on the top of the bearing will measure side to side alignment.

____

For models with a multi-piece trunnion

Loosen the (6) bolts [3] on the C Axis body support. Keep the bolts sufficiently snug to control adjustment.

Adjust the (8) set screws [4] until deviation between B at 90° and B at -90° is within 0.001".

Torque the (6) bolts [2] on the C Axis body support to 80 Ft-lbs (108 Nm).

Verify the alignment after the bolts have been torqued.

____

For models with a unibody trunnion

Jog rotary to B90. Set up an indicator on the highlighted surface as shown in the lower diagram .

Rotate B-axis 180 degrees (90 to -90).

Run out (NTE 0.010” TIR).

 Caution: If the measurement exceeds the tolerance then contact support.

6

Install and shim the A-frame trunnion support:

Move the B Axis to 90°.

Setup an indicator [1] against a machined surface of the C Axis body. Set the indicator to 0.

Use plastic zip ties [2] to pry the seal open while installing the A-frame support. This lets unwanted air and grease out of the assembly.

Install the A-frame trunnion support [3] over the bearings.

Remove the cable ties.

Turn the trunnion support clockwise until it is vertical.

 Note: The weight of the A-frame support will cause the trunnion to sag. The amount of sag is measured with the indicator that was previously setup on the side of the C Axis body.

____

For multi-piece trunnions

Adjust the shims [4] between the A-frame support and the base casting to remove the sag until indicator reads 0 again.

When the indicator reading is 0, torque the (4) bolts. Refer to Haas Fastener Torque Specification.

Verify the reading after bolts are torqued. Adjust the shims again if necessary until the indicator reads 0.

____

For models with unibody trunnion

Determine the amount of shim stock [4] needed to raise the Trunnion arm so the indicator reads 0.005".

The indicator [1] value will change once the support is torqued.

With indicator still in place:

  • Torque trunnion support bolts to appropriate values.
  • Check indicator to make sure it reads between the range of

Trunnion arm raised (0.005” to  0.010”).

 Note: For unibody trunnions, the shim location may also be used to correct the C-axis to X-Y plane perpendicularity instead of shimming the saddle trucks.

 Caution: Use equal amount of shims on each side of the A-frame support. Unequal shims will cause the A-frame support to pull the trunnion to the side.

Verify the B Axis of rotation alignment to the Y-Z plane (Step 2). Loosen the bolts and tap the A-frame support side to side if necessary to correct the B axis to Y-Z plane alignment.

7

Set C-axis perpendicular to X/Y plane:

Move the axes to

UMC-750's........X= -10.5" & Y=0."

UMC-1000's......X=-17.0" & Y=-0."

Zero an indicator [1], on a Ground Block [2], 1/2" off the edge at the rear of the platter (Mag-Base on Spindle), with C at 0 Degrees

Rotate C-Axis to 180°.

Move Y axis, and ground block, in Y Axis negative direction until you are 1/2" away from platter edge, and take the perpendicularity measurement

Adjust the shims until the average error is within 0.0005" end to end.

 Note: For unibody trunnions, the shim location under the bearing support may also be used to correct the C-axis to X-Y plane perpendicularity instead of shimming the saddle truck.

Caution: Shim either two front trucks or two rear trucks with the equal shim.

Note: Shim one truck at the time to maintain the X to Y squareness.

Verify the measurements after all bolts are torqued.

Verify the X to Y alignment in Step 2.

9

Check C-axis perpendicularity to X/Y plane:

Align the indicator centered over the C-axis bore with the Y-axis at -10.

Jog positive in the Y-axis and align the indicator over the center of the last section of the platter and make a mark at this spot with a washable marker.

Insert 1-2-3 block as shown and set the indicator to zero.

Remove the block and rotate the platter 90 degrees, following the marked spot with the indicator.

Insert block back between the indicator and platter. Note reading.

Repeat the previous two steps, taking readings with the platter at 180, 270 and 360 degrees.

Multi-piece trunnion:  (NTE 0.0005")

Unibody trunnion: (NTE 0.001")

Install the B Axis and C Axis intersection tool:

Jog the C Axis to 0°.

Push [EMERGENCY STOP].

Clean the table.

Guide the shaft of the adapter [1] while you slowly lower it into the center bore.

Attach the adapter to the table with (2) screws [4] and (2) T-nuts.

Attach the alignment bar [2] to the adapter with (3) screws [3].

Snug the (3) screws to allow for adjustments in the next step.

2

Align the B/C intersection tool with the C Axis:

Put an indicator on the front side of the alignment bar near the base.

Release the [EMERGENCY STOP]. Push [RESET] to clear any alarms.

Jog across the tool in the X Axis to find the high spot.

Set the indicator to 0.

Jog the C Axis 360°.

Lightly tap the base with a rubber mallet to adjust the radial error on the alignment bar.

Note: Adjust the alignment bar to half of the measured error, because you are measuring the diameter error.

Jog the C Axis 360°.

When correctly adjusted the radial error is less than 0.0002" (0.005 mm).

3

Check the B/C intersection:

Center the indicator [1] on the front side of the alignment bar near the top of the cylinder.

Jog across the tool in the X Axis to find the high spot.

Zero the indicator.

Jog the C Axis 360°.

For a machine with a Classic Haas Control change:

  • Parameter 151:20 (B-axis CHK TRAVL LIM) to 0.
  • Parameter 1314 (ROTARY AXIS CENTER DEVIATION IN X) to 0.

For a machine with a Next Generation Control change:

  • Parameter 6.021 (B-axis CHK TRAVL LIM) to FALSE.
  • Setting 254 (5-Axis Rotary Center Distance) to 0.

Push [ZERO RETURN]. Then push [ALL].

Jog the B-axis to -90°.

Note: The rotary positions are for reference only.

Put an indicator [1] on top of the alignment bar.

Jog in the Y-axis to find the high point.

Set the indicator to 0.

Jog across the alignment bar in the X-axis [2].

Jog the B-axis to adjust the alignment bar parallel to the X plane.

Set the indicator to 0.

Jog the Y-axis to 0.

Caution: Make sure the indicator assembly is clear of the B-axis movement.

 Caution: Do not move the Z-axis.

2

Jog the B-axis to +90°.

 Caution: Make sure the indicator assembly is clear of the B-axis movement.

Jog the Y-axis [1] to find the high point on the alignment bar.

Note: Do not set the indicator to 0.

Jog across the alignment bar in the X-axis.

Jog the B-axis to adjust the alignment bar parallel [2] to the X plane.

When the alignment bar is parallel to the X plane, the indicator reading is the change needed in the Z-Axis (∆Z=indicator reading).

Record the value shown on the indicator. In this example the indicator now shows 0.0015". ∆Z is 0.0015".

3

Do these calculations to get the value for CHC Parameter 1314 or NGC Setting 254. (In this example the difference in readings for the B-C intersection (∆Z) is 0.0015".):

  • ∆Z / 2 x 10,000 = CHC Parameter 1314 / NGC Setting 254
  • 0.0015 / 2 = 0.00075
  • Round down to 4 decimal places: 0.00075 = 0.0007 (NGC Setting 254)
  • 0.0007 x 10,000 = 7 (CHC Parameter 1314)

Set Parameter CHC Parameter 1314 (Rotary Axes Center Deviation in X) or NGC Setting 254 (5-Axis Rotary Center Distance), to the calculated value.

In this example, set parameter CHC Parameter 1314 to 7 or NGC Setting 254 to 0.0007.

Cycle the power to save CHC Parameter 1314 or NGC Setting 254.

Repeat Steps 1-3 to verify that the value for ∆Z is less than 0.0002" (0.005 mm).
