How do we know if we have achieved the best sequence of a nested part?

Typically, a row snake, or a column snake will produce a decent sequence. The total rapid movement is a good indication. You can check this out by plotting your nest with the FastCAM template. Go to the menu View. Select Change Display, and Select “template” under plotter labels. Double left click on the white box below “template” to Browse for the standard FastCAM template – C:\Program Files\FastCAM\template.cam.

Click okay to accept the settings and then click on the printer icon to obtain a print preview of your nest with a template that also shows a range of information. One of these info is “rapid” in lengths. That’s the distance the torch will have travel between parts. A good sequence would be minimising this distance.
