Straight end facing cuts can be made by specifying X, Z and F. By adding K a cone-shaped face is cut. The amount of coning is referenced from the target. That is K is added to the value of X at the target.
Any of the four ZX quadrants is programmed by varying U, W, X, and Z. The coning is positive or negative. The following figure gives a few examples of the values required for machining in each of the four quadrants.
During incremental programming, the sign of the number following the U and W variables depends on the direction of the tool path. If the direction of a path along the X-axis is negative, the value of U is negative.G94 Address Relationships: [S] Start position.
