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 ...

Contour offset approach to spiral toolpath generation with constant scallop height
Computer-Aided Design, 2003Abstract Recently, the application of high-speed machining (HSM) is recognized as an economically viable manufacturing technology. Even though more HSM centers have increasingly been utilized, the conventional toolpath generation methods are usually employed in practice. But the conventional methods have inherent limitations for the HSM application.

Spiral tool-path generation with constant scallop height for sheet metal CNC incremental forming
The International Journal of Advanced Manufacturing Technology, 2010A spiral tool-path generation method with constant scallop height for the sheet metal CNC incremental forming was proposed based on triangular mesh model. On the basis of the curvatures estimation of triangular mesh model, the calculation method of spiral tool-path interval with constant scallop height was discussed.

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.

In this paper, we present a cutter location (CL) surface deformation approach for constant scallop height tool path generation from triangular mesh. The triangular mesh model of the stereo lithography (STL) format is offset to the CL surface and then deformed in accordance with the deformation vectors, which are computed by the slope and the curvature ...

Plunge milling plays an important role in machining of components with cavity structures. As a non-continuous material removal strategy, residual material is inevitably remained between two adjacent plunge cutter locations, also named as scallop. Large scallop height causes machining error, as well as fluctuations of cutting width in the following ...

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.

ABSTRACT Spatial and temporal variations in the meat weight of sea scallops were examined in the Georges Bank fishery. From 1998–2007, 31 commercial scallop vessels supplied 145 dissections from the last tow of their fishing trip. During the dissection process we recorded the shell height, meat weight, sex, gonad weight, and visceral tissue weight ...
