9.1 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.
In principle, grinding involves two different types of technological sequence:
● external cylindrical grinding and
● dressing.
During external cylindrical grinding, cylindrical workpieces are machined on their overall
diameter 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.
