6.15. TOOL RADIUS COMPENSATION
In normal turning work the path of the tool has to be calculated and defined taking its
dimensions into account so as to obtain the required dimensions of the part produced.
Tool compensation enables the contour of the part to be programmed directly without
taking the dimensions of the tool into account. The CNC automatically calculates the path
to be followed by the tool, based on the contour of the part and the tool dimensions stored
in the tool table.
Every time a tool (T2.2) is selected the CNC automatically applies the tool length
compensation (X,Z,I,K) stored in the table, without having to program any G code. If
P604(5) is 1 the tool length compensation is effective when M06 is executed.
There are three preparatory functions for tool radius compensation:
G40 : Cancellation of tool radius compensation
G41 : Left hand tool radius compensation
G42 : Right hand tool radius compensation
Parameter P600(1) = 0 and axes
Parameter P600(1) = 1 and axes
