Trimming line development method of auto panel part with undercutting flange
Finite Elements in Analysis and Design, 2015In most of auto-panel manufacturing, trimming is generally performed before flanging. Therefore, the acquisition of the optimal trimming line is one of the keys to obtain an accurate shape of a product. It is not easy to obtain a reasonable trimming line for auto panel part with undercutting flange.

Molds for Meshes: Computing Smooth Parting Lines and Undercut Removal
IEEE Transactions on Automation Science and Engineering, 2009We consider the problem of computing a parting line for a mold for a complex mesh model, given a parting direction, and the related problem of removing small undercuts, either preexisting, or resulting from the parting line. Existing parting line algorithms are unsuitable for use with complex meshes: the faceted nature of such models leads to a parting

Making Line Undercut Structure by Incremental Laser Shock Forming
International Journal of Precision Engineering and Manufacturing, 2019A novel technology to plastically deform line undercut structures by pulsed laser, named as incremental laser shock forming (ILSF) of sheet metal, is presented in this paper and is investigated by experiments and numerical simulations. The deformation of a line undercut structure can be considered as the accumulation of several point undercuts, the ...

Transmission Line Characterization of Undercut-Ridge Traveling-Wave Electroabsorption Modulators
IEEE Photonics Technology Letters, 2008An experimental analysis of the electrical properties of traveling-wave electroabsorption modulators with undercut waveguides is presented. Modulators of varying ridge widths and amounts of undercut are fabricated and tested to compare characteristic impedance, effective index, microwave loss, and optical bandwidth.

NON-UNDERCUTTING CONDITIONS OF ROLLER GEAR CAMS
Transactions of the Canadian Society for Mechanical Engineering, 2003 The undercutting conditions in a planar cam can be predicted by comparing the radius of the curvatures of the pitch curves with the radius of the cutter.

Abstract Gear tooth surfaces being in line contact at every instant are considered. The dimensions of the contacting surfaces must be limited in order to avoid: (i) the appearance of the envelope of lines of contact on the generating surface Σ1 and (ii) the appearance of singular points on the generated surface Σ2.

ABSTRACT In order to study the topographic contrast of line-edge patterns in a scanning ion microscope (SIM) using helium (He) beam, a Monte Carlo simulation of secondary elect ron (SE) emission from silicon (Si) by the impact of He ions in the energy range of tens of keV is performed. The edges with overcut and undercut profiles for different sidewall
