Contour Offset Approach to Spiral Toolpath Generation With Constant Scallop Height

CAD Computer Aided Design, 2003
Abstract 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.

On Estimation of Scallop Height from CNC Part Programs

2019
Today, 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, 2004
Multi-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.

Constant Scallop Height Algorithm of Self-Adaptive Tool Orientation with Toroidal Cutter

Advanced Materials Research, 2012
Using a 5-axis NC machining tool enables the tool to be oriented in any spatial direction to access a given point. This means interference can be avoided and the position of the tool can be optimized. This paper presents a new approach to generate gouging-free tool paths for constant scallop-height machining using 5-axis toroidal milling.

Plunge milling with constant scallop height by adaptively modifying the step interval for pocket wall

The International Journal of Advanced Manufacturing Technology, 2018
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 ...

Adaptive scallop height tool path generation for robot-based incremental sheet metal forming

AIP Conference Proceedings, 2016
Incremental 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, 2004
Generation 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.

Spiral tool-path generation with constant scallop height for sheet metal CNC incremental forming

The International Journal of Advanced Manufacturing Technology, 2010
A 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.
