HEIDENHAIN MANUALplus 4110 233
4.9 Drilling/Milling Patterns
Cycle parameters
 X, Z starting point
 C spindle angle (C-axis position)—default: Current spindle angle
 Z1 starting point of pattern: Position of 1st hole/slot (polar
coordinates)
 C1 angle of 1st hole/slot: Starting angle (polar coordinates)
 ZE end point of pattern—default: Z1
 Wi angle increment (pattern spacing)—default: Holes, slots, etc.
are arranged at a regular spacing on the circumference.
 Q number of holes/slots—default: 1
 T tool number
 S spindle speed / cutting speed
 F feed per revolution
The pattern positions are defined with "ZE – Wi" or "Wi – Q."
MANUALplus also interrogates the parameters that are required for
machining the respective elements.
Cycle run
1 Positioning (depending on the machine configuration):
 Without C axis: Position to "spindle angle C."
 With C axis: Activate C axis and position to "spindle angle C" at
rapid traverse.
 Manual mode: Machining starts from current spindle angle.
2 Calculate the pattern positions.
3 Position to starting point of pattern.
4 Execute drilling/milling operation.
5 Position for next machining operation.
6 Repeat steps 4 and 5 until all machining operations have been
completed.
7 Position to starting point Z and deactivate C axis.
