safety distance(S)calculations
:
● S>(t1+t2)×V+6 mm
t1: SLA-3 response time(max.5ms)
;
t2
:
bending machine stop time
;
V
:
bending machine fast closing speed
● Determine bending machine braking distance by grating-rule, then add
6mm
Note:
If different value from the calculations,take the bigger one as the
safety distance.
4.2 Light Beam Position
All beams position as following fig. when SLA-3 device work's normally,
E1 beam should be positioned at 2-3mm behind the top tool tip
Fig.4-2 Light Beams Position
The point is the position from fast speed press changed to working
speed, which is calculated as per the distance from the point to the
workpiece, generally the value is set as per the machine protected
overrun distance at 6mm-15mm.
