Scaling with TRANS SCALE

Application

The TRANS SCALE function lets you change the scale of the contours or distances to the datum, thereby evenly enlarging or shrinking them. This enables you to program shrinkage and oversize allowances, for example.

Use the TRANS SCALE RESET function to reset scaling.

Description of function

Scaling is a modal function that is in effect as soon as it has been defined in the NC program.

Depending on the position of the workpiece datum, scaling is carried out as follows:

  • Workpiece datum at the center of the contour:
  • The contour is scaled uniformly in all directions.

  • Workpiece datum at the bottom left of the contour:
  • The contour is scaled in the positive X and Y axis directions.

  • Workpiece datum at the top right of the contour:
  • The contour is scaled in the negative X and Y axis directions.

Presets in the machine

If you enter a scaling factor SCL less than 1, the contour will be reduced in size. If you enter a scaling factor SCL greater than 1, the contour will be enlarged.

When scaling, the control takes the coordinate input and dimensions from all cycles into account.

If Scaling is active, the control displays it on the TRANS tab of the Status workspace.

Input

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.

Notes

  • This function can be used only in the FUNCTION MODE MILL machining mode.
  • Switching the operating mode with FUNCTION MODE

  • If you execute a change of scale with TRANS SCALE or Cycle 11 SCALING FACTOR, then the control overwrites the current scaling factor.
  • Cycle 11 SCALING FACTOR

  • If you want to reduce the size of a contour with inside radii, make sure to select an appropriate tool. Otherwise, residual material might remain.
