This paper presents a numerical investigation of the effects chamfered and sharp cemented carbide tools using finite element method-based DEFORM-2D software cutting parameters on different machining characteristics during orthogonal AISI 1045 steel. The objective is to study interactions between chamfer width, angle, angle speed feed rate temperature, effective stress wear depth. These were inv...

High speed machining of hardened steels for manufacturing dies and molds offers various advantages, but the productivity often limited by mainly tool life. This study investigates the influence of edge preparation in cubic boron nitrite (CBN) cutting tools on process parameters and tool performance by utilizing practical finite element (FE) simulations and high speed orthogonal cutting tests. T...

This paper will examine the current chamfer and vector distance transforms for encoding objects as distance elds. A new vector distance transform is introduced which uses the city-block chamfer distance transform as a basis. Detailed error analysis using real CT data is presented demonstrating the improved accuracy the new approach gives over existing methods. The production of a sub-voxel accu...

We describe a shape-based chamfer matching method for recovering 3D hand pose using a monocular camera. Although some variants of chamfer matching methods incorporated edge direction information, of which the direction term is set empirically, so they may fail in different application scenario. In this paper, a collaborated directional chamfer matching (CDCM) is proposed. The direction term can...

Chamfer distances are discrete distances based on the propagation of local distances, or weights defined in a mask. The medial axis, i.e. the centers of the maximal disks (disks which are not contained in any other disk), is a powerful tool for shape representation and analysis. The extraction of maximal disks is performed in the general case with comparison tests involving look-up tables repre...

Subgingival margins are often required for biologic, mechanical, or esthetic reasons. Several investigations have demonstrated that their use is associated with adverse periodontal reactions, such as inflammation or recession. The purpose of this prospective randomized clinical study was to determine if two different subgingival margin designs influence the periodontal parameters and patient pe...

Chamfer distances are step-based on various grids. The fourdimensional FCC grid is the extension of usual face-centred cubic into four dimensions. There two types steps, and thus, weights used. Operational research, namely linear programming Gomory cut applied to describe optimal paths hence, their weighted lengths, chamfer distance.
