Abstract
Methods of maintaining part stability for side milling are presented. Stock to leave is modeled for a roughing operation of a part based on material properties of the material of the raw stock and a design of the part. A finishing toolpath for the side milling is generated based on the stock to leave, minimum wall thickness of the part, maximum stock height, and a number of machining levels.
Claims21
A method of maintaining part stability for side milling comprising:
- modeling stock to leave for a roughing operation of a part based on material properties of the material of a raw stock and a design of the part;
- and
- generating a finishing toolpath for the side milling based on the stock to leave, minimum wall thickness of the part, maximum stock height, and a number of machining levels.
A method of maintaining part stability for side milling comprising:
- performing a series of physical machining tests to gather stiffness data for a material over a series of thicknesses and a series of cutting forces;
- establishing a machining ratio for the material based on the stiffness data, the machining ratio comprising a ratio of part thickness to stock height;
- and
- setting stock to leave for a roughing operation of a part based on the machining ratio for the material and a design of the part.

A method of maintaining part stability for side milling comprising:
- calculating a point load representative of dynamic cutting forces during machining;
- modeling deflections of a part from the point load by applying the point load to the part in a physics based modeling;
- and
- setting stock to leave for a roughing operation of the part from raw stock based on the deflections.
