After getting our shop put back together after some major renovation this summer. I started a new project but for the love of me I am having a hard time getting my feed rates and depth of cuts calculated. To that my teacher doesn't know what is wrong with my speed and feeds. I think my major concern is the depth of cuts which is where I hope someone can explain on how they determine the DOC.
I am cutting into 6061 Aluminum with a 1/4" 4 Flute HSS end mill. I will be using a Haas Mini Mill with a Max spindle speed of 6000.
I have been through all my books and all my calculations come out the same but I am more concerned about my DOC. I have been doing a 0.0625 DOC at 12 IPM with at 6000 RPM.
Can someone point out what I might be doing wrong and what calculations that you would use in situation. I know I must have something wrong so any help will be great. |
