Cycles
1 Brief Deskription
Aim of the module:
With the help of this module you will get to know the various cycle parameters under ShopMill and
ShopTurn.
Description of the module:
This module explains the various parameters that are called up in tabular form in the cycle masks. In
the course of this the relationship and the differences of the parameters to the individual cycles and
techniques are pointed out.

Basic aspects
2. 1 Cycles
Cycles are sub-programs (technology-orientated functions) for the execu-
tion of a repeatedly occurring operation on a work piece.
Cycles can be selected comfortably via Softkeys and can simply be Para-
metered by means of input masks.
Programmed cycles are inserted in G-Code or step-chain-programs as a
program step and can be re-selected and newly set by parameter at any
time.
The following functionality is available both in ShopMill and ShopTurn
Technology-orientated cycle selection by means of Softkeys
Input masks for die cycle parameters (cycle masks) with help pictures
and animations
Context-sensitive online-help for every Input window
Support for the contour input (geometry processor)
