Basic Functions - Dimension Preset
Purpose : Set the current position for that axis to an entered dimension
Example : To set the current X axis position to be 45.800mm
Application tips for lathe : The diemension preset function provides a very convenience way to
monitor your cross feed in lathe maching. Let's assume the DRO's X axis
is installed as per the diagram below.
Z (+)
X (+)
scale reading direction
a) Set the X axis display to be the DIA display in the SETUP mode
b) Make a slight first cut at the work piece along the Z axis, after finish this first cut, move the tool
away from the work piece along the Z axis, it is important that don't move the X axis at all in
order to keep the X axis position right at the cutting position of making this first slight cut.
c) Measure the work piece by a caliper. ( i.e, The measured diameter of the work piece is 45.80mm )
d) Enter this measured diameter into the DRO by dimension preset function.
e) Since the X axis tool position is now at the position of making the first slight cut, and it is the measured
diameteral reading of the work piece, if we preset this dimension into the DRO, then from now on,
whatever dimension shown on the X axis display, it is the actual diameteral dimension of the work
piece.
