Part 1 Programming
Note 1: In a single block, G51 must be specified in the mode of G40, and the G50 can be specified in offset
mode, the G51 must be cancelled by G50 after the scaling is performed
Note 2: The position display is a coordinate value after scaling.
Note 3: If a setting value is regarded as a scaling rate without specifying P, then this setting value is the
scaling rate specified by G51, it is valid to change this value by other commands.
Note 4: Whether the scaling function of each axis is valid, which is determined by parameter, the circular
arc radius is specified by R in the mode of G51, and this function is always valid regardless of the
parameter setting.
The additional axis of scaling function is always valid.
Note 5: The scaling function is invalid to the manual operation; it is valid only for the DNC, Auto or MDI.
Note 6: Suppose that the canned cycle Z axis moves, the scaling is not available for the following
motions.
* Cut-in value Q and retraction value of peck drilling cycle (G83, G73).
* The movement value of X and Y in fine boring (G76) and back boring (G87).
Note 7: G27, G28, G29, G30 and G92 must be used in the mode of G50.
Note 8: The scaling results are rounded; the move amount may become zero. In this case, the block is
regarded as a no movement block, and therefore, it may affect the tool movement by cutter
compensation C. (See the Section 6.3.6 (8))
Note 9: Resetting
(a) The resetting is performed in G51 mode, the original coordinate becomes the current coordinate
value or scaled coordinate. Therefore, the movement after presetting is determined by the increment or
absolute.
If the resetting is performed at point B, the point A in the program is regarded as the point B. When the
movement command of point D is performed, the following movement is determined by the absolute or
incremental commands.
* Increment
