Fig.2.19 Q1 Command
A perpendicular vector can also be generated by specifying G41.2 or G42.1
in the next block as follows:
Example: N6 G41.2 Y-400 Z0
(2) Q2 command
With a program specifying a linear-to-linear connection, up to two
compensation vectors are generated. In this case, the second vector is
deleted by inserting a Q2 command. The Q2 command has no effect on
circular interpolation.
Example) N4 Y-200 Z-200 Q2
The second vector (V2) is deleted, and only V1 is used as a compensation vector.
