4.2 Tool Nose Radius Compensation Offset Path
4.2.1 Inner and Outer Side
Inside is defined that an angle at intersection of two motion blocks is more than or equal to 180°;
Outside is 0~180°, which is shown 4-15.
Fig. 4-15
4.2.2 Tool Traversing when Start-up Tool
3 steps to execute tool nose radius compensation: tool compensation creation, tool
compensation execution and tool compensation canceling.
Tool traverse is called tool compensation creation (start-up tool) from offset canceling to G41 or
G42 execution.
Note: Meanings of S, L, C in the following figures are as follows:
S ―― Stop point of single block; L ―― linear; C ―― circular, R ―― tool radius compensation
；
α―― angle between two blocks.
