4.1 Working with cycles
Before you can use the cycles, you must set the workpiece zero point
and ensure that the tools you are going to use are described. You enter
the machine data (tool, feed rate, spindle speed) in Teach-in mode
together with the other cycle parameters. In Manual mode, you must
program these machine data before calling a cycle.
Define the individual cycles as follows:
 Position the tool tip with the handwheel or the jog keys to the
starting point of the cycle (only in Manual mode)
 Select and program a cycle
 Graphically test the cycle
 Execute the cycle
 Save the cycle (only in Teach-in mode)
Cycle starting point
In Manual mode, cycles are executed from the "current tool position."
In Teach-in mode, you enter the starting point as one of the
parameters. The MANUALplus moves to this position at rapid traverse
by the shortest path (diagonal) before executing the cycle.
The cutting data can be taken from the technology
database using the Proposed technology soft key. For this
database access, a type of operation is permanently
assigned to every cycle.
Danger of collision!
If the tool cannot approach the next starting point on the
shortest path without colliding with the workpiece, you
must define an auxiliary position with the Rapid traverse
positioning
cycle.
