Cutting Foam

[jhedlund58]

I cut foam... mostly for H.S. drama club... very light and the drama director loves it... maybe cause i do it for free...

on the chip out... i have found that that happens to me when last pass is very shallow... i use aspire... and they allow u to change the depth of the passes on profile cuts... i made my last pass deeper... .2 or even .25.. and the chip out went away... i was having the problem with wood too. and this approach has been very satisfactory

I did my 1" foam cuts all it one pass... how deep are you cutting per pass?

i cut conservatively at .125 per pass... which is why i try to get my last pass to .2 or so... i sure there are others that wood not agree with this thin of a pass... time is no issue for me... and i like the results. maybe it is my buddy48 with the 2.2 spindle.. i use the chip calculator and keep rpm between 12000 and 14000... then adjust the speed accordingly
