(f) Reciprocal feed *
For tapping, boring and other similar operations, individual feedrates can be specified for
advance and return feed.
By using this feature, tapping operation which will be completed before the spring in a
tapper is fully extended can be performed. In addition, this mode provides various advan-
tages for different types of operation. In boring operation, cycle time can be shortened. In
reaming operation, return movement of the cutting tool does not leave scratches on the fin-
ished surface.
