SYM101 | Accuracy - Intermittent Operation Position |
SYM201 | Interruption - Saw Side Gripper Not Gripping |
Collect all the offcut ends from a batch of cutting from the machine and measure the distance of the gripper datum holes from the end of the bar, grouping under each profile type. Measure to the nearest 0.5mm. Collect at least 50 samples
Reading 8.5mm | Reading 10.0mm | Checking offcut has a square end |
Example recording:
Outer Frame
10.0, 9.5, 10.0, 9.5, 7.0, 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0
T Sash
6.5, 7.0, 7.5, 7.0, 7.0, 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0 , 7.0
T-Door
6.5, 7.0, 7.5, 7.5, 7.5, 7.5, 7.5, 7.5, 7.5, 7.5, 7.5, 7.5
The example recordings show that the outer frame has a variance of 7mm to 10mm.
The T Sash and door are fairly consistent
The following measurements assume a bar with a square end
Pass | The hole is consistently at 7mm +/1mm
(Can vary between 6mm and 8mm, but with the median at 7mm) |
Fail | Any hole is greater than 8mm
Any hole less than 6mm |
Failure Mode | Resolution |
---|---|
Hole position is inconsistent | Check correct function of infeed wheel clutch
Check correct function of infeed datum clamp then
|
Hole position is consistent, but outside the tolerance range | Follow procedure |
