Optimization of Tool Path for Uniform Scallop-Height in Ultra-Precision Grinding of Free-Form Surfaces [PDF]

Nanomanufacturing and Metrology, 2019
Free-form surfaces have been widely used in complex optical devices to improve the functional performance of imaging and illumination quality and reduce sizes. Ultra-precision grinding is a kind of ultra-precision machining technology for fabricating free-form surfaces with high form accuracy and good surface finish.

Efficient Cutting Path Planning for a Non-Spherical Tool Based on an Iso-Scallop Height Distance Field

Chinese Journal of Aeronautics
Iso-scallop height machining means, when machining a freeform surface, the scallop height between any two neighboring tool paths on the surface will be a constant (i.e., the given threshold), which is preferable among various freeform surface machining strategies due to its high machining efficiency as well as better machine tool's dynamics.

Estimation of Scallop Height in Freeform Surface CNC Machining

International Journal of Advanced Manufacturing Technology, 2019
Scallop height is primarily used to assess the quality of complex freeform surface parts manufactured on multi-axis computer numerical control (CNC) machines. Currently, the inspection methods used in practice are slow and expensive as they need sophisticated equipment and skilled personnel.

Constant Scallop-Height Tool Path Generation for Three-Axis Sculptured Surface Machining

CAD Computer Aided Design, 2002
This paper presents a new approach for the determination of efficient tool paths in the machining of sculptured surfaces using 3-axis ball-end milling. The objective is to keep the scallop height constant across the machined surface such that redundant tool paths are minimized.
