Circle center

Cartesian coordinates

With the I, J, and K or G29 NC functions, you define the 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.

; Circle center at the last position

  • I, J, and K
  • The circle center is defined in this NC block.

  • G29
  • The control assumes the most recently programmed position as the circle center.

I, J, and K or G29 correspond to the CC Klartext syntax with or without axis values.

Tip

With I and J, you define the circle center in the X and Y axes. In order to define the Z axis, program K.

Polar coordinates

With the I, J, and K or G29 NC functions, you define a pole. All polar coordinates reference the pole.

  • I, J, and K
  • The pole is defined in this NC block.

  • G29
  • The control takes over the most recently programmed position as the pole.

I, J, and K or G29 correspond to the CC Klartext syntax with or without axis values.
