3.4 TOOL OFFSET FUNCTIONS
The following three kinds of tool offset functions are provided: tool length offset function, tool
position offset function (used for simplified tool radius offset), and tool radius offset C function*
(used for tool radius offset for complicated shape).
1. If the tool wear offset function is selected optionally, the offset amount used in the tool
length offset function and the tool radius offset function is the sum of the tool geometry
offset amount and the tool wear offset amount.
2. Two types of tool offset number designation methods are provided and which method
should be used can be selected by the setting for a parameter.
pm4029D0 = 0: H/D used in common
D0 = 1: H/D used for individual functions
An H code is used for the tool length offset function and a D code for the tool position off-
set and tool radius offset functions.
3.4.1 Tool Offset Data Memory
To execute the tool offset functions, the tool offset amount must be written to the tool offset data
memory in advance. Depending on the selected specifications, the following number of memo-
ries is available.
