Notes
The finishing of contours on the turned item can either be accomplished by
direct call-up of the contour subprogram or with the support of cycles.
The purpose of this document is particularly the variant of a direct call-up.
Note
For the sake of argument it is assumed that the work piece is already
loaded in the chuck on the finished diameter 70 mm and that the contour
has been roughed out with the usual finishing allowance.
For a subprogram call-up the following layout of the calling main pro-
gram is recommended:
1. Tool call-up followed by the statement of the technology data
2. Positioning at rapid traverse rate to the safety plane above the con-
tour starting point and simultaneously activation of the tool radius
correction
3. Call-up of the subprogram
4. Deactivation of the radius correction, possibly on the way to the tool
changing point
The editor printout below lets you follow through the entire program. (The
program section referring to the present problem starts at block N70)
