Cutting plastic for first time, perhaps I am going wrong a tip or two be great thanks

I suppose it is worth mentioning once in a while for newbies... if you want to surface anything with an end cutter you need non-plunging tooling.
If your tool cuts all the way to the middle it will leave a graunchy, chewed up line behind when you go sideways

I would definately recommend a 1 or 2 flute cutter with a slow spiral, your 4 flute cutter doesnt leave much chip clearance. I would rough first then use the 0.8mm left to finish both sides, very sharp tooling and flood coolant/high pressure air recommended.

Hi James,

Many thanks for your help and the pointers. I will try and get some one and two flute cutter for the next job. I had to crack on with what I had for know. Perhaps Trend cutters will be good if you or anyone could provide a cutter reference that would be great so I could the right ones. I have a coolant tank on my mill but know coolant that is another job I will try the compressor though!

All the best

Thank you Robin,

I cut the little job without any balls ups. I was most worried about damaging the machine, cutter or material. That was all fine and the finish will do from the 4 flute for the job in hand. I will get some better cutters perhaps some Trend one and two flute ones.

Many thanks
