Accuracy Check Procecedure for Gripper Datum Hole Position

Applies To

ZX5 Only

Symptoms

Number Description / Link
SYM101 Accuracy - Intermittent Operation Position
SYM201 Interruption - Saw Side Gripper Not Gripping

Diagnostic Method

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


...Check that the profile is square from the top to bottom face. Unfortunately, the physical hard stop is at the bottom face, yet the measure position is at the top face. This will lead to incoinsistencies in the measurement that will make the test more complicated. A good idea would be to ensure all the bars have a square end to start with, but this is not always practical.
...The gripper system is designed to cope with a top to bottom "un squareness" of +/- 1.5mm in normal operation - this is the range of "on" switching allowed in the gripper switch mechanism

Example recording:

Outer Frame

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

Pass / Fail

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

Resolutions

...Always use a bar with a square end for test pieces during any resolution measurements
Failure Mode Resolution
Hole position is inconsistent Check correct function of infeed wheel clutch

Check correct function of infeed datum clamp
