Abstract
The stable metal removal rate in milling depends on the dynamic characteristics of the tool-holder-spindle system. We present a methodology for determining the permissible dynamic characteristics based on the intended cutting operation. We produce a template that bounds the tool-tip frequency response function (FRF). Measured FRFs can be compared against the template to check cutting performance. The template can be used in design to match the spindle system to the intended application. The template accounts for lobing effects, multiple modes, process damping, and static stiffness. It accounts for damping variability, producing a safe-side estimate. Experimental results illustrate the template's use.
