Tool length compensation (G43, G44, G15)
With this function it is possible to compensate possible differences in length between the
programmed tool and the tool being used.
The tool length compensation is applied on to the axis indicated by function G15 or, in its absence,
to the axis perpendicular to the main plane.
If G17, tool length compensation on the Z axis.
If G18, tool length compensation on the Y axis
If G19, tool length compensation on the X axis.
Whenever one of functions G17, G18 or G19 is programmed, the CNC assumes as new longitudinal
axis (upon which tool length compensation will be applied) the one perpendicular to the selected
plane.
On the other hand, if function G15 is executed while functions G17, G18 or G19 are active, the new
longitudinal axis (selected with G15) will replace the previous one.
The function codes used in length compensation are as follows:
G43: Tool length compensation.
G44: Cancellation of tool length compensation.
Function G43 only indicates that a longitudinal compensation is to be applied. The CNC starts
applying it when the longitudinal (perpendicular) axis starts moving.
When G43 is programmed, the CNC compensates the length in accordance with the value of the
tool offset selected with code D, or (in its absence) the tool offset shown in the tool table for the
selected tool (T).
Tool values R, L, I, K should be stored in the tool offset table before starting machining, or should
be loaded at the beginning of the program via assignments to variables TOR, TOL, TOI, TOK.
If no tool offset is selected, the CNC takes D0 with R0 L0 I0 K0.
Function G43 is modal and can be canceled via G44 and G74 (home search). If general machine
parameter "ILCOMP=0", it is also canceled on power-up, after executing M02, M30 or after
EMERGENCY or RESET.
G53 (programming with respect to machine zero) temporarily cancels G43 only while executing a
block which contains a G53.
Length compensation can be used together with canned cycles, although here care should be taken
to apply this compensation before starting the cycle.
