Optimizing Machining Processes for Precision: An Example using calculated cutting forces

Abstract

A common machining problem is to find the maximum material rate possible by adjusting the cutting speed, width of cut, and depth of cut for a given process. This maximum is found within given boundaries, or constraints, such as power and speed limits of the machine tool. The tolerance limits, or process precision, can also be considered as constraints on the problem: what is the maximum material removal rate possible and still make the component within the tolerances? A different approach is to search for the highest precision solution to a machining process. Putting a higher priority on precision than production speed usually requires a deeper understanding of the process. For example, increasing speed increases the material removal rate, but obviously you cannot simply go slower to increase precision - you have to understand the process and do some other kind of work (precision engineering) to improve the process. This paper uses an example involving the calculation of cutting forces to examine component errors due to deflection during machining.
