Peripheral milling: 3-D radius compensation
with workpiece orientation

The TNC displaces the tool perpendicular to the direction of

movement and perpendicular to the tool direction by the sum of the

delta values DR (tool table and TOOL CALL). Determine the

compensation direction with radius compensation RL/RR (see figure,

traverse direction Y+). For the TNC to be able to reach the set tool

orientation, you need to activate the function M128 (see "Maintaining

the position of the tool tip when positioning with tilted axes (TCPM):

M128 (software option 2)" on page 523). The TNC then positions the

rotary axes automatically so that the tool can reach the defined

orientation with the active compensation.

This function is possible only on machines for which you

can define spatial angles for the tilting axis configuration.

Refer to your machine manual.
The TNC is not able to automatically position the rotary

axes on all machines. Refer to your machine manual.
Note that the TNC makes a compensating movement by

the defined delta values. The tool radius R defined in the

tool table has no effect on the compensation.

Danger of collision!

On machines whose rotary axes only allow limited

traverse, sometimes automatic positioning can require

the table to be rotated by 180°. In this case, make sure

that the tool head does not collide with the workpiece or

the clamps.
