With turning you can machine both at constant spindle speed and constant cutting speed.
Use FUNCTION TURNDATA SPIN to define the speed.
With turning you can machine both at constant spindle speed and constant cutting speed.
Use FUNCTION TURNDATA SPIN to define the speed.
If you machine at constant cutting speed VCONST:ON, the control modifies the speed according to the distance of the tool tip to the center of the turning spindle. For positioning movements toward the center of rotation, the control increases the table speed; for movements away from the center of rotation, it reduces the table speed.
For processing with constant spindle speed VCONST:Off, speed is independent of the tool position.
With FUNCTION TURNDATA SPIN you can define a maximum speed for the constant speed.
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
