Nesting to the edge of sheets ?

Post by Dale Wills »

Hi,

Just got a quick question in regards to the setting in control nest about nesting to the edge of a sheet. If this setting is ticked or selected, am I right in saying that the cutter will trim off half the diamter of the cutter on any parts nested along the outside edges? So if I am using an outline cutter that is 10mm in diameter it should be trimming 5mm off the outer edges plus any collar setting?
Cheers,
Dale

Hello Dale,

When selecting Nest to Edge of Sheet, Control Nesting does not figure to remove any amount of material from the edge of part which is on the outside edge of sheet. Untrue edges on your sheet may cause some chips to fly off cutter as it follows the outside edge, but again there is no step over figured when this setting is selected.

Having not used this option much, I've recently noticed some things about this function.

The Nest to edge option appears to nest ONLY to the edge indicated by the nest direction, and NOT to both axis pop-up pins on our machine. It's possible that the pin index coordinates are off, but I have ZERO misalignment when doing flip-ops suggesting that they are correct. I had assumed :oops: that nest to edge indexed the sheet to BOTH x and y pins.

Recently this was an issue when programming parts already cut to size by another outfit, so I ended up making a mask board to index the cut with a set of COMPIN shadow cut with a mating cut file. Anybody else still learning stuff everyday?! :joker:

Unfortunate side effect in the software. If we make it nest perfect in the corner on both axe,s nesting will be drastically slower. In Nesting Parameters, nesting in the Upper Left and Lower Right will force it all the way in the corner.

Ideally what you should have done is to use Nest to Edge of Sheet, Scrap Part Recovery in the Load Screen, and turn off outline cuts in Settings. Scrap Part Recovery will keep the software from trying to nest on a sheet and instead just create code for the single part. That combined with Nest to Edge of Sheet puts the part in the corner. You'll be running parts one at a top, but that tends to be the case when you are cutting features on a presized part.
