Abstract

This work seeks to identify, model, and compensate for machine compliance in tungsten carbide mould manufacturing. The machine compliance, including the spindle and tool, is characterized by direct measurement as well as cutting trials. This information will be used to create a grinding force model that may be used in the manufacturing of moulds with complex geometry. This task is complicated by the fundamentally three-dimensional nature of the mould geometry. An adequate compliance model must capture the full 3D characteristics of the machine/tool compliance in order to achieve some measure of success. Furthermore, the relationship between cutting force and material removal is decidedly nonlinear at micron-level depths of cut. This must also be captured to control workpiece form error. This work approaches the modelling task using observations made in a series of micro-grinding trials that span a wide swath of the cutting parameter space for micro grinding. We also will collect data on the role of machine/tool compliance. These results will guide the formulation of a model for compensating for machine compliance using cutting force as the primary monitoring signal.
