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
1 LN X+31,737 Y+21,954 Z+33,165 TX+0,0078922 TY–0,8764339
TZ+0,2590319 RR F1000 M128
Straight line with 3-D compensation
LN:
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
