CNC Programming Coordinate System Setting
The position of terminal point of the movement command in the Z-axis can be shifted + or - by as much as the value set in the offset memory. This function can be used by setting the difference between the tool length assumed during programming and the actual tool length of the tool used when the work is performed into the offset memory. Direction of offset G43 + side offset G44 - side offset In any case of absolute or incremental command, the offset amount that has been set into the offset memory assigned by H-code is in G43, added to, and in G44, subtracted from the coordinate value of the terminal point of the axis movement command. The coordinate value after the calculation becomes the terminal point. Assignment of offset amount Assign offset number using H-code. The offset amount that has been set in the offset memory is added to or subtracted from the programmed command value for Z-axis. Note -1 When the offset amount is changed due to a change of the offset number, the offset value changes to the new offset amount, but it is not added to the old offset amount. Coordinate system shift G50, This command created a new coordinate system in which the coordinate (X, Z) of a point on the tool (i.e. Tool nose) on the current coordinate system correspond to (X + u, Z+ w). The X and Z values are diameter in case of diameter designation and radius in the case of radius designation.
