Default 1/4" Compression for Prefinished Ply

Is anyone using a 1/4 compression bit for cutting out 3/4 prefinished plywood? If so are you able to do it in one pass?

Thanks,
Bruce

Bruce,

I have done prefinished 3/4" maple with a 1/4" compression 2+2 @ 130ipm with the only trouble being the chips packing the cut slot. I went to a 3/8" compression 2+2 and stayed there just because it cut easier and cleared chips and was able to get the IPM up to 180 with my setup. Probably could have pushed harder but I am in general not in a hurry so play conservative.

Bruce, with the spindle and vacuum, I would use a 3/8" 2+2 and you should be able to run it at 500ipm, keep in mind I do not know the specs on the Panther, but I'm running full depth 1 pass 600 IPM at 17k RPM. I onion skin small parts and have them cut first. What cabinet software are you using? Most of them can be set for automatic onion skin for anything under ?? square inches.

I normally prefer the 3/8" compression, but I have used a 1/4" compression in a single pass (1800rpm and 200ipm). The finish with a 3/8" seems to be better, and I feel more comfortable at faster feed rates with a 3/8".

Thanks everyone for the info. I'll stick with the 3/8". It seems like a safer bet.
