Process

To ensure that the cycle is executed successfully, the following requirements must be fulfilled:

• 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 start and end points must be reachable collision-free, starting from the current position at the height of the retraction plane.
• The contours used were already programmed using #CONTOUR BEGIN / #CONTOUR END.

Infeed in Z takes place according to the parameterisation either vertically along the Z axis at the beginning of the approach movement (contour) or obliquely in space during the approach movement. Retraction in Z takes place analogously.

The tool is moved along the contour at the specified feedrate at each machining height. After the contour is removed, the tool is retracted and, if necessary, repositioned at the starting point for the next pass.

The use of finishing allowance at the edge is only allowed when tool radius compensation is active (@P9). In this case, the offset to the contour during roughing is increased by the finishing allowance. During finishing, the finishing allowance at the edge is removed first and then the finishing allowance at the base.

If individual contour elements were specified at a feedrate during the contour definition, it is activated for the particular element (independently from @ P14). If a finishing allowance with tool radius compensation was specified, the selected feedrate is only activated during the finishing pass.
