Imaginary tool nose numbers 0 and 9 are used when the tool nose center
coincides with the start position. Set imaginary tool nose number to
address OFT for each offset number.
Bit 7 (WNP) of parameter No. 5002 is used to determine whether the tool
geometry offset number or the tool wear offset number specifies the
direction of the virtual tool nose for tool nose radius compensation.
Imaginary tool nose number 0 to 9
Virtual tool nose directions 1 to 8 can be used only in the G18 (Z–X) plane.
For virtual tool nose 0 or 9, compensation is applied in both the G17 and
G19 planes.
Tool nose radius compensation value
(Tool nose radius value)
This value is set from the MDI according to the offset number.
When the options of tool geometry compensation and tool wear
compensation are selected, offset values become as follows :
