Process

To ensure that the cycle is executed successfully, the following requirements must be met.

• The tool radius is defined by V.G.WZ_AKT.R
• Tool length compensation is active.
• The spindle speed must be selected before the cycle is started.
• The contour pocket can be reached without collision starting from the current position at the height of the retraction plane.
• The contours used were already programmed using #CONTOUR BEGIN / #CONTOUR END.
• The defined contours for the edge contour and islands are closed, i.e. start and end points are identical.

In the cycle, the tool is fed vertically along the Z axis, if possible slightly offset from the residual material in order to allow increased feedrates. The tool then plunges into the residual material with its full circumference. Once the centre of the residual material is reached, it is removed parallel to the contour. Infeed in the XY plane is specified by the input parameters. However, it is internally limited to the tool radius to avoid residual material.

If there is residual material in several places, the tool is retracted several times along Z and then re-approached. If a slightly offset infeed to the residual material is not possible, helical plunging is used provided it was previously activated by the input parameters.

If individual contour elements were specified with a feedrate during contour definition, this has no influence on the milling feedrate.

Attention

For contour spigot milling, it is possible that the maximum infeed in the XY plane is violated and the milling cutter enters the material at full circumference. This must be considered when the milling feed is selected.
