Know it is not a big deal for those who machine in metric but for those in inches it is a real pain. This would be a "good" mod for us inch users. |
Well, you are right about the 50ipm in steel. Joakim's 5 axis mills it a about 1500 ipm. On the other hand, I read a post on a guitar builder's forum last night where I saw the guy posted his speeds for cutting abalone shell for inlays. 7.5ipm.
"If feed calls for 2.7 and MadCam rounds down to 2 the difference is a 25% difference."
Can you explain what you mean by the above statement? Who is calling for the feedrate? How are you arriving at the called for numbers?
BTW I talked with Joakim today and he said he would take a look at making this available.....I don't know when, or how long it will be, or for that matter, if it can be done with his alogrithems (sp).
