003 respectively. Point can be machined when enter corresponding SDM coordinate and “0.000”
appears in screen by moving machine table. This function can save great plenty of time in
production.
3.2
Preset datum of SDM Coordinate
Compared with the way of zeroing at current point, the another way (presetting datum of SDM
coordinate) can set zero point of SDM more accurately and quickly without moving the machine table.
As the figure showed right, center point is the datum of
ABS, the position of point E, F, G, H is (-60, -45), (60, -45),
(60, 45), (-60, 45) in ABS coordinate.
A Enter SDM 000 and preset the position of point O
as (60, 45), which means the point E is the datum
of SDM 000;
B Enter SDM 001, preset the position of point O as
(-60, 45), which means the point F is the datum of SDM 001;
C Enter SDM 002 and set the position of point O as (-60, -45), which means the point G is the
datum of SDM 002;
D Enter SDM 003, preset the position of point O as (60, -45), witch means the point H is the
datum of SDM 003;
Pay attention that the preset value is negative to the actual value of position in ABS. If set “SDM
DIR” as “1” in initial system settings, the caution is not necessary. The value DRO accepts is equal to the
negative of the enter value.
STEPS:
1. Set “SDM DIR” as “1” in initial system settings;
2. Set the center point of the work-piece as the datum of ABS;
Line AB is parallel to X axis, line AD is parallel to Y axis.
Move machine table; align the milling cutter with point O.
The machine table remain still while presetting;
3 Set point E as the datum of SDM 000;
Enter SDM 000.
The position of point E is (-60, -45), press.
