Inclined machining (option 9)

Application

When pre-positioning the tool during machining, workpiece positions that are difficult to reach can be machined without collisions.

Requirements

  • Machine with rotary axes
  • Kinematics description
  • To calculate the tilting angles, the control requires a kinematics description prepared by the machine manufacturer.

  • Advanced Functions Set 2 (software option 9)

Description of function

Inclined machining with incremental process

Inclined machining can be implemented by changing the inclination angle in addition to the normal linear movement while function FUNCTION TCPM or M128 is active, e. g. L X100 Y100 IB-17 F1000 G01 G91 X100 Y100 IB-17 F1000. In this process, the relative position of the tool’s center of rotation remains the same while inclining the tool.

Example

* - ...

12 L Z+50 R0 FMAX

; Position at clearance height

13 PLANE SPATIAL SPA+0 SPB-45 SPC+0 MOVE DIST50 F1000

; Define and activate the PLANE function

14 FUNCTION TCPM F TCP AXIS POS PATHCTRL AXIS

; Activate TCPM

15 L IB-17 F1000

; Pre-position the tool

Inclined machining using normal vectors

In case of inclined machining using normal vectors, the tool angle of inclination is achieved by means of straight lines LN.

To execute inclined machining with normal vectors, function FUNCTION TCPM or miscellaneous function M128 must be activated.
