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 CNC PILOT 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.
