Manual machining using cycles (functions)

4.4.1

Principle operating sequence

Functionality
You can perform the following functions manually:
● Drilling centric
● Tapping
● Groove cycles/Expan. groove
● Thread cutting
● Rough turning of contours
When manually machining these functions, the operating sequence is essentially executed in the same way.
Requirement
The following requirements must be fulfilled before you can execute the functions:
NOTICE
Damage to the tool, workpiece or machine
In machining operations, a spindle rotating in the wrong direction can cause serious damage to the tool, workpiece or
machine.
Check the direction of rotation of the spindle before pressing the following key.

Description
This input value describes the position of the circle end point in the X axis. The input
value is evaluated as absolute position (in the diameter).
This input value describes the position of the circle end point in the Z axis. The input
value is evaluated as absolute position.
This input value describes the position of the circle center in the X axis. The input
value is evaluated as absolute position (in the diameter).
This input value describes the position of the circle center in the Z axis. The input
value is evaluated as absolute position.
This toggle field selects whether a circle must be traversed in the clockwise or coun-
terclockwise direction.
