Circular arc with center

Cartesian coordinates

With the G02, G03, and G05 NC functions, you program a circular path around a circle center.

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.

  • Change the following contents as needed:
  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions, e.g. with M91
  • Paths of program calls

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.

 
Tip

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.

  • G02
  • Circular path in clockwise direction, corresponds to the C Klartext syntax with DR–.

  • G03
  • Circular path in counterclockwise direction, corresponds to the C Klartext syntax with DR+.

  • G05
  • Circular path without direction of rotation, corresponds to the C Klartext syntax without DR.

    The control uses the most recently programmed direction of rotation.

Circular path C

Polar coordinates

With the G12, G13, and G15 NC functions, you program a circular path around a defined pole.

  • G12
  • Circular path in clockwise direction, corresponds to the CP Klartext syntax with DR–.

  • G13
  • Circular path in counterclockwise direction, corresponds to the CP Klartext syntax with DR+.

  • G15
  • Circular path without direction of rotation; corresponds to the CP Klartext syntax without DR.

    The control uses the most recently programmed direction of rotation.

The polar coordinate angle H corresponds to the PA Klartext syntax.
