HEIDENHAIN MANUALplus 4110 81
4.1 Working with Cycles
Help graphics
The functionalities and parameters of the cycles are illustrated in the
graphic support window. These graphics usually show an external
machining operation. The Circle key allows you to switch to the help
graphics for internal machining, and
to switch between the help graphics for internal and
external machining.
Elements used in the graphic support window:
Broken line: Rapid traverse path
Continuous line: Feed path
Dimension line with arrow head on one side: "Directional
dimension"—the algebraic sign defines the direction.
Dimension line with arrow head on both sides: "Absolute
dimension"—the algebraic sign has no effect.
DIN macros
You can integrate DIN macros in cycle programs. Make sure that the
DIN macros do not contain any zero point shifts.
Graphical test run (simulation)
Before executing a cycle, you can graphically test the contour details
and the machining sequence (see “Graphic Simulation” on page 68).
Cycle keys
A programmed cycle is not executed until Cycle START is pressed.
Cycle STOP interrupts a running program. With thread cutting, the
current cut will be completed before cycle execution is interrupted.
During a cycle interruption you can:
Resume cycle execution with "Cycle START." The control will always
resume execution of the cycle at the point of interruption—even if
you have moved the axes in the meantime.
Move the axes using the jog keys or handwheels.
Terminate the machining process with the Cancel soft key.
Danger of collision!
Cycle programming: With DIN macros, the zero point
shift is reset at the end of the cycle. Therefore, do not use
any DIN macros with zero point shifts in cycle
programming.
