Operation
The cutting part tools actually used are tool nose or cutting edge which has dimensional variation with
tool center or the related point of tool rest, so the control system has to compute the corresponding
coordinates of tool center or the related point of tool rest according to the actual coordinate position of
tool nose or cutting edge (namely the actual coordinate position of parts profile), which is called tool
compensation.
Input the new tool parameter values in [Compensation (=)] input interface (as shown in Fig. 3-41) if tool
nose radius is altered after tool wear, tool sharpening or tool change, avoiding the trouble to modify the
programmed processing procedure.
Fig. 3-41 Tool Parameters Screen
To make tool compensation (including tool diameter compensation and tool length compensation)
e
ffective, parameter “turn on radius compensation” should be set as “true”. Code G43 (positive offset)
and G44 (negative offset) are used for tool length compensation; G41 (left compensation) and G42 (right
compensation) for tool radius compensation; G40 (cancel tool radius compensation) and G49 (cancel
tool length compensation) are used for canceling tool compensation.
Only when tool compensation codes and G00/G01 are used together can the tool compensation be
enabled.
