There are two ways to define the tool orientation:
„ In an LN block with the components TX, TY and TZ
„ In an L block by indicating the coordinates of the rotary axes
Example: Block format with tool orientation
Example: Block format with rotary axes
1 LN X+31.737 Y+21.954 Z+33.165 TX+0.0078922 TY–0.8764339
TZ+0.2590319 RR F1000 M128
LN : Straight line with 3-D compensation
X, Y, Z : Compensated coordinates of the straight-line end point
TX, TY, TZ : Components of the normalized vector for workpiece
orientation
RR : Tool radius compensation
F : Feed rate
M : Miscellaneous function
