- Operation of tool center point control (type 2)
The following item is the same as for tool length compensation along
the tool axis:
- Tool holder offset
The following items are the same as for tool length compensation in a
- Operation in tool length compensation in a specified direction
- Machine configuration example and equation for rotation axis
- Tool offset by tool number
When the tool offset by tool number is used, the tool length
compensation amount corresponding to a tool number (T code) is used
for tool center point control.
- Tool life management
When tool life management is used, the tool length compensation
amount of the tool used is used for tool center point control.
- Three-dimensional cutter compensation
Tool center point control and three-dimensional cutter compensation
can be used at the same time.
Three-dimensional cutter compensation is applied to a specified tool
tip point. Three-dimensional cutter compensation, however, is not
performed momentarily in the middle of a block; it is performed only at
the end of a block.
- Three-dimensional coordinate conversion
When tool center point control (type 2) is used during three-
dimensional coordinate conversion, the tool axis orientation (I, J, K) is
also subjected to three-dimensional coordinate conversion.
- Rotation axis rollover
Whenever using tool center point control (type 2), set
bit 2 (ROL) of parameter No. 1009 to 1 to perform
rotation axis rollover.
- Axis name extension
When I, J, and K are used as axis names by axis
name extension, tool center point control (type 2)
cannot be used.
- Manual intervention
When manual intervention is applied to a rotation axis with the manual
absolute switch off, the compensation vector is calculated using the
rotation axis position that was found immediately before manual
Example: When the manual absolute switch is turned off with B
positioned to 30.0, then a manual intervention by 1.0 degree is
applied to the B-axis, the machine coordinate position of the B-
axis is 31.0. Then, starting automatic operation sets the absolute
coordinate position of the B-axis to 30.0. In tool center point
