G47 Text Engraving (Group 00)

---

G47 lets you engrave a line of text, or sequential serial numbers, with a single G-code. To use G47, Settings 29 (G91 Non-Modal) and 73 (G68 Incremental Angle) must be OFF.

---

NOTE: Engraving along an arc is not supported.

---

*D - Controls the smoothness level, D1(rough), D2(medium), or D3(finish). If D is not used then default is D3.
*E - Plunge feed rate (units/min)
F - Engraving feed rate (units/min)
*I - Angle of rotation (-360. to +360.); default is 0
*K - Sets the max corner rounding value. If K is not used then default is K 0.002 inch or 0.002 mm depending on how setting 9 is set.
*J - Height of text in in/mm (minimum = 0.001 inch);
default is 1.0 inch (1.0 mm)
P - 0 for literal text engraving
- 1 for sequential serial number engraving
- 2 for the date and time formated as (MM/DD/YYYY HH:MM:SS)
- 32-126 for ASCII characters
*R - Return plane
*X - X start of engraving (When using G17 plane)
*Y - Y start of engraving (When using G17 plane)
*Z - Depth of cut (When using G17 plane)
*Y - Y start of engraving (When using G19 plane)
*Z - Z start of engraving (When using G19 plane)
*X - Depth of cut (When using G19 plane)

*indicates optionalLiteral Text EngravingThis method is used to engrave text on a part. The text should be in the form of a comment on the same line as the G47 command. For example, G47 P0 (TEXT TO ENGRAVE), will engrave TEXT TO ENGRAVE on the part.

---

NOTE: On Mills G47 can only be used on the G17 plane while on Lathes G47 can be used on either the G17 or G19 plane. G47 can not be used on the G18 plane.

---

---

NOTE: Corner rounding can cause engraved characters to appear rounded and make them harder to read. To improve the sharpness and readability of engraved text, consider lowering the corner-rounding values with a G187 E.xxx value before the G47 command. Suggested starting E values are E0.002 (inch) or E0.05 (metric). Command a G187 alone after the engraving cycle to restore the default corner-rounding level. Refer to the example below:

The characters available for engraving are:A-Z, a-z 0-9, and ` ~ ! @ # $ % ^ & * - _ = + [ ] { } \ | ; : ' " , . / < > ?Not all of these characters can be entered from the control. When programming from the mill keypad, or engraving parenthesis (), refer to the following Engraving Special Characters section.This example creates the figure shown. Engraving Program Example


In this example, G47 P0 selects literal string engraving. X2.0 Y2.0 sets the starting point for the text at the bottom left corner of first letter. I45. places the text at a positive 45 angle. J.5 sets the text height to 0.5 units-in/mm. R.05 retracts cutter to 0.05 units above part after engraving. Z-0.005 sets an engraving depth of -0.005 units. F15.0 sets an engraving, XY move, feedrate of 15 units per minute. E10.0 sets a plunge, -Z move, feedrate of 10 units per minute.Special CharactersEngraving Special Characters involves using G47 with specific P values (G47 P32-126).P- values to engrave specific characters

Example:To engrave $2.00, you need (2) blocks of code. The first block uses a P36 to engrave the dollar sign ($), and the second block uses P0 (2.00).

---

NOTE: Shift the X/Y start location between the first and second line of code to make a space between the dollar sign and the 2.

---

This is the only method to engrave parenthesis ().Engraving Sequential Serial NumbersThis method is used to engrave numbers on a series of parts with the number being increased by one each time. The # symbol is used to set the number of digits in the serial number. For example, G47 P1 (####), limits the number to four digits while (##) would limit the serial number to two digits.

---

NOTE: Engraving along an arc is not supported.

This program engraves a four digit serial number. Initial Serial NumberThere are two ways to set the initial serial number to be engraved. The first requires replacing the # symbols within the parenthesis with the first number to be engraved. With this method, nothing is engraved when the G47 line is executed (it is only setting the initial serial number). Execute this once and then change the value within the parenthesis back to # symbols to engrave normally.The following example will set the initial serial number to be engraved to 0001. Run this code once and then change (0001) to (####). The second method for setting the initial serial number to be engraved is to change the Macro Variable where this value is stored (Macro Variable 599). The Macros option does not need to be enabled.Press [CURRENT COMMANDS] then press [PAGE UP] or [PAGE DOWN] as needed to display the MACRO VARIABLES page. From that screen, enter 599 and press Down cursor.Once 599 is highlighted on the screen, type in the initial serial number to engrave, [1] for example, then press [ENTER] .The same serial number can be engraved multiple times on the same part with the use of a macro statement. The macros option is required. A macro statement as shown below could be inserted between two G47 engraving cycles to keep the serial number from incrementing to the next number. For more details, see the Macros section of this manual.Macro Statement: #599=[#599-1]Engraving Around the Outside of a Rotary Part (G47, G107)You can combine a G47 Engraving cycle with a G107 Cylindrical Mapping cycle to engrave text (or a serial number) along the outside diameter of a rotary part.This code engraves a four digit serial number along the outer diameter of a rotary part. Engraving Date and timeUsing the address code P2 with G47 will engrave the Date and time the engraving is being done. The date and time format will be MM/DD/YYYY HH:MM:SSThis code engraves the date and time. For more details on this cycle, refer to the G107 section.
