This article reports on tool path generation by the iso-scallop height method for the three-axis ball-end milling of sculptured surfaces. In order to achieve the specified machining accuracy, constant scallop height machining requires an understanding of the three-dimensional machining geometry and the use of iterative approaches.

On Estimation of Scallop Height from CNC Part Programs
2019Today, complex freeform surfaces are widely used on parts in automobile, aerospace, and die– mold industries. Multi-axis computer numerical control (CNC) machines are used to manufacture such parts as they need tighter tolerances and high surface finish to meet functional and aesthetic requirements.

MULTI-POINT MACHINING WITH ANTI-GOUGING AND SCALLOP HEIGHT CONTROL
Transactions of the Canadian Society for Mechanical Engineering, 2004Multi-Point Machining (MPM) is a tool positioning strategy for 5-axis machining of complex surfaces. A multi-point tool position results in tangential contact between the tool and the design surface at several points. By machining at several points on the tool simultaneously, material removal rates can be improved.

Adaptive scallop height tool path generation for robot-based incremental sheet metal forming
AIP Conference Proceedings, 2016Incremental sheet metal forming is an emerging process for the production of individualized products or prototypes in low batch sizes and with short times to market. In these processes, the desired shape is produced by the incremental inward motion of the workpiece-independent forming tool in depth direction and its movement along the contour in ...

Efficient five-axis machining of free-form surfaces with constant scallop height tool paths
International Journal of Production Research, 2004Generation of efficient tool paths is essential for the cost-effective machining of parts with complex free-form surfaces. A new method to generate constant scallop height tool paths for the efficient five-axis machining of free-form surfaces using flat-end mills is presented.

Journal of Shellfish Research, 2012
ABSTRACT Generalized linear mixed models were developed for allometric relationships in Atlantic sea scallops (Placopecten magellanicus). These models used environmental covariates such as depth, latitude, geographic area, fishing pressure, population density, and season. This study makes several technical improvements to existing allometric models. We

This paper introduces a discovery about the geometric property of the tangent vectors of a constant scallop height (CSH) curve. Based on this discovery, a new tool path generation algorithm for plane envelope grinding a convex surface is presented, which aims at grinding convex surface with a cup wheel on five-axis NC machine tool.
