Solidcam I machining

1

Hello guys I am new here I got some questions about I machining.

I am 23 years old I programming most of the time trying to get very optimized programs I got a new workpiece 1.4101 X14 I need to cut 52mm to get the block in shape 220x180x60 the finish part looking like a triangle and there are 2 pockets 22.5 mm and 33.5 mm deep so I need to cut much material i wanted to use a 16mm cutter but it take alot of time I use level 3 but i go up now to lvl8 but the time still looking not so well for my feeling and the other thing is the cutter should survive this any one got a good idear to make it faster (maybe other tools other job) or is someone here who know which tool and data I should use for this material I just got good experience in 1.4305 but I am still not happy with the tools.

Machine data

Dmu75 mono block
20.000rpm
Sk40
Tools
we use this one D12-16
Cooling oil/water

Sorry for my Englisch. I watching all videos and I love them and I trust In your knowledge.

Thanks alot

That tool is 35 long why not cut the pocket in 2 steps? I deep rough leaving .5mm stock use good waveform Machining strategy with chip thinning. And go back in and take a finish cut.

To cut everything it took around 2 hours

@GabrielHecker looks like you’re doing the top hat. I would cut it the full depth the outside. Then do a profile cut around the outside for a good finish. That would cut the time down significantly.

What is the smallest internal corner radius of your part? If you are going to use single tool, I would use the largest diameter cutter I can.

12.5 in pocket so I can use a 20mm but I only use 12-16 most time the 20 cutters are other and I never used them I will test them question is should I use the data from I machining or should I lower the cutting angle the other cutters i use 30.7 chip thickness of 0.068 ae from 0.84 in stainless steel the other cutters have 4 teeth and they are vhm ultra ms 38°
