Laser Cut Kerf Test Slot And Tab Clearance Test 3mm

This clearance test was originally intended to be a kerf test for laser cutters and engravers. The tab dimensions are 15mm x 3mm. The slot dimensions incrementally change from 15mm x 3mm and then increase by 0.1mm increments in one direction and decrease by 0.1mm in the other direction. Some laser beam patterns are not perfectly circular or square and the resulting cuts may be slightly different in the x or y axis. By cutting slots and tabs in both the x and the y orientation, they can be measured and test fit to see if you have to compensate when designing your slots and tabs. However, without having first compensated for variations in the material thickness, machine motion system accuracy, and any offsets applied by the tool path generating software, this is not really a kerf test. It is more of just a general fit and clearance test since the kerf is only one of the many variables not accounted for.
