Stiffness of Structures and Drives in Fast Milling Machines

05/06/1999  A stiffness requirement for high speed milling machines is determined by examining the stiffness of current generation high speed spindles. The desire for stability against chatter dictates that the stiffness of the machine structure and drives, when reflected to the tool tip exceed the spindle/tool holder/tool stiffness.

Milling machine tool stability and performance

The milling machine structure has a different contribution to the relative flexibility between a tool and a work-piece. There are generally two parts of a whole structure: a main frame and the parts associated with the spindle. This dynamic investigation will be focused on the second part. An example of transfer function of such a structure is known in Fig. 1. Among the parts of the shown ...

If you ask for too much, you drive up the cost to manufacture. Too little and you reduce the quality of your product. If you want the finish that’s cheap and cheerful to hit with most CNC machines, specify no finer than a 64 µ” finish. A 32 µ” finish won’t add much cost, and a 16 or even an 8 µ” finish can be done, but now you’ll be looking at increasing costs.

On the other hand, due to material and transportation costs, there is also a longterm trend to reduce the weight of the machines which also - leads to more vibrations in critical frequency ranges. Numerical analysis of vibrations is a ...
