...Zhiyang Yao; Ajay Joneja High speed milling (HSM) has great potential use in die/mold cutting, but traditional machining plans do exploit HSM capabilities effectively. An important consideration in HSM is to limit cutting force variations, and one way to do so is to reduce cutter-workpiece...

.... To determine the shape of the part model, the values of independent variables (design parameters) should be assigned by mapping between the standard classification structure and the design parameters. The method of constructing a table parametric model (Fig. 3-1) is described with an example of mold...

...Sara McMains; Xiaorui Chen We consider the problem of whether a given geometry can be molded in a two-part, rigid, reusable mold with opposite removal directions. We describe an efficient algorithm for solving the opposite direction moldability problem for a 2D “polygon” bounded by edges that may...

...Yong Chen; David W. Rosen Mold design can be a difficult, time-consuming process. Determining how to split a mold cavity into multiple mold pieces (e.g., core, cavity) manually can be a tedious process. This paper focuses on the mold construction step of the automated mold design process...
