80 4 Cycle Programming

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. The

machine data (tool, feed rate, spindle speed) are entered with the

other cycle parameters in Teach-in mode. 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).

Starting point of cycles

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. MANUALplus moves to this position in rapid traverse by

the shortest path (diagonal) before executing the cycle.

Cycle transitions

Finishing cycles in expanded mode are interrupted at the contour end

point. This enables you to sequentially link several finishing cycles and

thus finish a selected part of the contour in a single uninterrupted cut.

MANUALplus, however, knows only the contour area of the cycle that

is presently being machined. After finishing this contour area, the tool

is positioned for a subsequent horizontal contour element. If the

subsequent element is not horizontal, the tool is positioned to the

contour starting point before the defined contour area is finished. All

positioning is done at feed rate speed.

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.
