Overview of cycles

Cycles are generally applicable technology subroutines used to realize a certain machining
process, such as plung-cut grinding, dressing, or longitudinal grinding. These cycles are
adapted to individual tasks by parameter assignment.
The system offers various grinding cycles for
● external cylindrical grinding and
● dressing.
During external cylindrical grinding, cylindrical workpieces are machined on their overall di-
ameter using machining cycles. The infeed axis X traverses at right angles to the longitudinal
axis Z. The cycles support the grinding behind the turning center.
Grinding tools need to be dressed after a certain time in service to compensate for worn
wheels and to restore their original profile. Dressing of a wheel pursues two objectives:
● Shaping: Shaping: Provides for the desired shape of the wheel.
● Sharpening: Restores the cutting capability of the wheel.

The following cycles can be carried out using the SINUMERIK 802D sl control system:
CYCLE410
CYCLE411
CYCLE412
CYCLE413
CYCLE414
CYCLE415
CYCLE416
CYCLE420
The cycles are supplied with the tool box. They are loaded via the RS232 interface into the
part program memory during the start-up of the control system.
