4. Motion Control Instructions 4.8.3.7 G17, G18, G19: to specify the circular interpolation plane Function: The three instructions are used for deciding the selection of circular interpolation or helical interpolation plane and have no impact on the linear interpolation. While the program is being executed, the three work planes can be switched with each other. If no plane option is set, the initial state of system is XY plane (G17). Format: N_G17 N_G18 N_G19 Parameter Explanation: N_: The row number of G code in NC program The figure of planes is shown as follows: 4.8.3.8 G4: Dwell Instruction Function: Dwell instruction Format: N_G4 K_ Parameter explanation: N_:
The row number of G code in NC program K_: Specify the delay time, unit: second. Range: 0.001 second ~100000 seconds Instruction explanation: After the lathe completes the processing for some phase, the cutter need be stopped moving temporarily. At this moment, G4 can be utilized to make the cutter stopped for a period of time. Instruction example: N00 G1 X10000 N01 G4 K10 N02 G1 X20000 20000 10000 DVP-MC operating manual 4-207 Position
