SysMillContourSpigot - Mill contour spigot

This cycle is used to mill a contour spigot.

To carry out contour spigot milling, the contours of the blank and the individual spigots are transferred to the cycle. The cycle removes the area of the blank contour with the exception of the defined spigots.

The geometrical description of the blank and the spigot contours in the X and Y axes is provided by a contour definition Contour definition.

Up to 10 spigot contours can be added to the blank. They are also described by a contour definition. For spigot milling, they may not intersect with the blank contour.

It is possible to machine a contour spigot with different milling cutter radii. For more information on this, see the related Cycle description.

To mill the contour spigot, the tool is lowered to the side of the blank. With complex contour spigots it may be necessary to perform a second plunge into the raw material during surface machining. Here you can activate a helical plunging operation. The plunge radius is 50% of the tool radius if not otherwise specified but this can be changed by adding an input parameter. This cycle continues the vertical feed in Z after helical plunge is activated. Only then can the helical variant be used if a plunge takes place in the blank. If the milling cutter does not cut over centre, the plunge points can be calculated in advance and machined in a predrilling cycle.

In the cycle, the spigot is milled out incrementally parallel to the contour at each machining height. To avoid residue, infeed in the XY plane is limited to the tool radius.

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.
