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
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
Example: Block format with rotary axes
1 L X+31,737 Y+21,954 Z+33,165 B+12,357 C+5,896 RL F1000
M128
L: Straight line
X, Y, Z: Compensated coordinates of the straight-line
end point
B, C: Coordinates of the rotary axes for tool
orientation
RL: Radius Compensation
F: Feed rate
M: Miscellaneous function
