Compensating The Tool Angle Of Inclination With Function Tcpm (Option 9); Function - HEIDENHAIN TNC 620 User Manual

Multiple-axis machining | Compensating the tool angle of inclination with FUNCTION TCPM (option 9)
11.5 Compensating the tool angle of inclination
with FUNCTION TCPM (option 9)

Function

Refer to your machine manual.
The machine geometry must be specified by the machine
tool builder in the kinematics description.
FUNCTION TCPM is an improvement on the M128 function,
with which you can define the behavior of the control during the
positioning of rotary axes.
With FUNCTION TCPM, you can define the effects of various
functions yourself:
Effect of the programmed feed rate: F TCP / F CONT
Interpretation of the rotary axis coordinates programmed in the
NC program: AXIS POS / AXIS SPAT
Type of orientation interpolation between the start and end
positions: PATHCTRL AXIS / PATHCTRL VECTOR
Optional selection of a tool reference point and a center of
rotation: REFPNT TIP-TIP / REFPNT TIP-CENTER / REFPNT
CENTER-CENTER
Optional feed-rate limit to compensate movements in the linear
axes for motions with a rotary-axis component: F
If FUNCTION TCPM is active, the control shows the TCPM symbol in
the position display.
Danger of collision!
Rotary axes with Hirth coupling must move out of the coupling to
enable tilting. There is a danger of collision while the axis moves
out of the coupling and during the tilting operation.
Retract the tool before changing the position of the tilting axis
Programming notes:
Before positioning axes with M91 or M92, and before
a TOOL CALL block, reset the FUNCTION TCPM
function.
Only use ball-nose cutters for face milling in order to
avoid contour damage. In combination with other tool
shapes, make sure to use graphic simulation to test
the NC program for possible contour damages.
