Once all the points have been entered you can now start using them straight away. As long as the Message window
is displaying the text “
SDM MODE”
, the axis displays are showing the current position of the tool from the SDM co-
ordinate as displayed in the SDM window.
This direct entry of SDM co-ordinates is particularly useful when working on batch jobs or where centre or origin
co-ordinates of features, to be machined, can be read from drawings.
The displayed value after pressing [enter] will be of
opposite sign. This is because we are working-to-zero
relative to the ABS datum and we are currently at 0, 0.
