Thanks, well explain. Just, how to know we have a good feedrate ? Was it as soon it start to give bad edge cutting and dust .. that is too fast ? thanks
Greetings. We are glad to help you with any issues you may have. We believe a bad edge would mean you are running too fast. However, we would need more information on the tool and material to further assist you. You can contact us directly at info@onsrud.com. Thank you.
Thank you!
Thank you for the explanation. I was wondering if there are any impacts in tool wear if the Depth of Cut adjustments from your table are made. I am using a 56-287 (1/4" diam) and want to cut a 3/4" plywood in one cut (which would mean a 50% reduction in chip load and feed rate). What are your recommendations regarding this issue? Thank you
Greetings Gabriel. I will get with one of our in-house Technical Advisors to get you proper recommendations on this. Please stay by/Thank you.
Our Technical Advisor strongly recommends limiting the depth of cut for this tool to .375” in depth. This would result in machining the material in question in two passes rather in the single pass. For further assistance or tool recommendations you can contact our team directly at info@onsrud.com. Thank you.
@@LMTOnsrud Thank you for the fast reply. For the proposed depth of .375", how much should I reduce the chip load?
@@gabrielbranco2013 You are welcome. Thank you for subscribing. Our Technical Advisor recommends a 25% reduction to give you the best results.
Hello. I tried following your recommendations but the tool broke after a couple of minutes (it was brand new). I am trying to figure out if I did something wrong: I was cutting a .375" piece of plywood in on pass using 56-287, having set the feed rate to 180 ipm (18000rpm x 2 cutting edges x 0.005 chip load). Can you help me figure out what happened?
What are recommended feeds and speeds for Trespa 20mm with a 10mm chip breaker bit. Being cut on a heavy duty Morbidelli M600F. Thanks in advance.
what is chipload range ? ı am confuset. Does it tolerance on cam program?
cant find chip load for specific endmills..
i found somewhere here (youtube) table which looks like some kind of universal table, and i created web calculator for it: informatyksiedlce.pl/_PROJECTS/chipload_calc/ maybe you will find it usefull
It looks like at 1:37 your graphic reads that the bit has three flutes but you use 2 flutes in your formula. Should it have been 3 flutes in the formula, or am I not getting it?
Good afternoon - it should be two flutes though I know the slide shows three flute..The tooling shown is a two flute tool...I will try and get this corrected.
Olá.
1000 IPM equivale a a quantos mm/min ?
I'm from india.rcntly I purchased cnc machine for wood carving.main work is 3d.im using HSS tool 2flute ballnose.my spindle speed is 24000rpm.i want to know the diffrnt rpm for dfrnt wood.like teak wood tamarind wood.plywood.mdf.also workspeed.feedrate. 🙏
these are for a industrial machines what about an intery level machine,,
Can u explain in mm
Hello Abdul - thank you for contacting us. Though this video is explained in inches, the principles would still be the same for mm. Converting inches to mm 1" = 25.4 mm & 1mm = 0.03937". You will need to convert the inches to mm and then plug these values into the formulas depicted here. Hope this helps, but if you do have questions, you may contact our technical support for further information. Thank you.
I made a web calc which do exacly that: informatyksiedlce.pl/_PROJECTS/chipload_calc/
