Inclined turning
Application
In some cases, it might be necessary to bring rotary axes into a certain position in order to machine the workpiece as required. This can be necessary, for example, when you can only machine contour elements using a specific position due to tool geometry.
Requirement
- Machine with at least two rotary axes, one of them as a rotary table axis
- Software option Turning (#50 / #4-03-1)
Description of function
The control offers the following methods of inclined turning:
NC 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 | HEIDENHAIN recommends using FUNCTION TCPM with REFPNT TIP-CENTER. With FUNCTION TCPM and REFPNT TIP-CENTER selected, the tool location point is at the tool tip. The tool center of rotation is located at the tool center point. If you activate FUNCTION TCPM with REFPNT TIP-CENTER, a tool-tip radius compensation is possible in positioning blocks with RL/RR. | |
Cycle 800 | Use Cycle 800 ADJUST XZ SYSTEM to define an inclination angle. |
If you execute turning cycles with the functions stated above, 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.
