9 Tool Offsets 05.91
9.6 Tool length compensation (positive or negative)
9.6 Tool length compensation (positive or negative)
When length compensation is selected, compensation is positive. A negative tool length com-
pensation must be programmed with G16. The tool length compensation is effective in the axis
perpendicular to the CRC plane.
Example:
G16 UVW± U,V Plane selection (CRC plane)
W± The sign specifies whether the tool length compensation for axis W is
positive or negative.
Defining the sign
A plus sign is entered by the operator if the tool length compensation entered (P2 and /or P3)
is to be accounted for in the positive direction. If a minus sign is entered, the tool length
compensation applies in the negative direction.
9.7 Tool offsets for end mill
In the case of an end mill, the cutter radius compensation is active in the plane specified with
the corresponding preparatory function (geometry = P4, wear = P7) while length compens-
ation (geometry = P2, wear = P5) is effective in the third axis.
The following applies:
G17: Cutter radius XY cutter length Z
G18: Cutter radius ZX cutter length Y
G19: Cutter radius YZ cutter length X
It is also possible to incorporate a 4th or another axis using G16.
G16 X Y U Cutter radius in XY plane cutter length in U (positive direction)
G16 X Y Z– Cutter radius in XY plane cutter length in Z (negative direction)
The number “20” must be entered under P1 (tool type).
Radius
Length 1
P1 : Tool type (enter:20)
P2 : Geometry, length 1
P4 : Geometry, cutter radius
P5 : Wear, length 1
P7 : Wear, cutter radius
