It may sometimes be necessary for you to bring the swivel axes into a specific position to machine a specific process. This can be necessary, for example, when you can only machine contour elements according to a specific position due to tool geometry.
Application
Requirement
- Machine with at least two rotary axes
- Combined milling/turning (software option 50)
Description of function

The control offers the following methods of inclined turning:
Function | Description | Further information |
---|---|---|
M144 | The control uses M144 in subsequent traverse movements to compensate for tool offsets that result from inclined rotary axes. | |
M128 | With M128 the control behaves like with M144, but you cannot use cutter radius compensation outside of cycles. | |
FUNCTION TCPM with REFPNT TIP-CENTER | Use FUNCTION TCPM with the selection REFPNT TIP-CENTER to activate the virtual tool tip. If you activate inclined machining with FUNCTION TCPM with REFPNT TIP-CENTER, then tool-tip radius compensation is also possible without a cycle; that is, in traversing blocks with RL/RR. HEIDENHAIN recommends using FUNCTION TCPM with REFPNT TIP-CENTER. | |
Cycle 800 | Use Cycle 800 ADJUST XZ SYSTEM to define an inclination angle. |
If you execute turning cycles with M144, FUNCTION TCPM, or M128, then the angles of the tool relative to the contour will change. The control automatically takes these modifications into account and therefore also monitors the inclined machining operation.
Notes
- Threading cycles can be run with inclined machining only if the tool is at a right angle (+90°, or –90°).
- Tool compensation FUNCTION TURNDATA CORR-TCS is always active in the tool coordinate system, even during inclined machining.
