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.
• Both ends of longholes are reachable without collision at the height of the retraction plane
• The tool cuts across centre or the workpiece was predrilled (both ends of the longholes)

During the cycle, the longholes are approached at rapid traverse at the height of the retraction plane. The feed is first to the safety plane at rapid traverse along the Z axis followed by a feed to the machining height at the feed rate. Starting at this start point, an iterative feed takes place up to the new machining height at the feed defined in @P21 and the longhole is machined until the longhole depth @P4 is reached. The iterative infeed in Z per pass never exceeds the value of the maximum infeed in Z defined in @P5.

If “oscillating” is selected as infeed mode in Z defined in @P32, iterative infeeds in Z are executed by a lowering approach to the other end of the longhole at the feedrate defined in @P20. To completely remove the machining height, the longhole is machined horizontally at the feedrate defined in @P20 after an inclined plunge.
