General Mach Discussion / Re: Different speed in material and above
« on: September 14, 2016, 10:41:42 AM »I can get you some figures if you let me know your spindle power and what type of tool - 1flute or two flute etc.
Or you can look in to a program called HSMAdvisor its great for speeds and feeds but you will need to know how to set it for a small machine as it assumes industry size stuff
Once set correctly, the motor tuning never really gets looked at again, unless you alter the machine etc.
Is there a tool library feature in ArtCam - this is where i would set my feeds for each tool/material combination then its just a simple matter to choose the tool when doing the CAM and you always get the right speed settings etc.
I use 2m single flute carbide a lot in aluminium and on my machine i use 24,000rpm, 370mm/min feed, 1mm depth max, 0.59mm width max and it will run this all day.
You can tune differently though as it will also run a 5mm cut depth but only at a max of 0.1mm engagement - great for finish passes.
I use 1 Flute 2 mm end mill from sorotec - http://www.sorotec.de/shop/Cutting-Tools/END-MILLS/END-Mill-ALU-412/End-Mill-Z1--2-0mm-SL-5-ALU.html
There is tool library in ArtCAM and setting parameters for each tool is my next step.
My engraving does not go deeper than 0,5 mm so till now i did 2 step down's of 0,25 mm each.
When you say 1 mm max depth do you make that depth in single pass or you make it in a couple of passes (step downs) ?
