G76 X1.92 Z-2. Q60000 F0.2 D0.01 K0.04 (60 degree cut) ; G76 X1.92 Z-2. Q120000 F0.2 D0.01 K0.04 (120 degree cut) ; G76 X1.92 Z-2. Q270123 F0.2 D0.01 K0.04 (270.123 degree cut) ;

The following rules apply to the usage of Q:

  1. The start angle, Q, must be specified every time it is used. If no value is specified then a zero (0) angle is assumed.

  2. Do not use a decimal point. The angle of threading increment is 0.001 degrees. Therefore, a 180° angle must be specified as Q180000 and an angle of 35° as Q35000.

  3. The Q angle must be entered as a positive value from 0 to 360000.
