Last years analytical or finite element models of milling become more efficient and focus on more physical aspects, nevertheless the milling process is still experimentally unknown on a wide range of use. This paper propose to analyse with accuracy milling operations by investigating the cutting forces values, shape of cutting forces curves obtained for different cutting speeds, and related phe...

The material characteristics such as size effect are one of the most important factors that could not be neglected in cutting the material at nanoscale. The effects of anisotropic nature of single crystal materials in nano-cutting are investigated employing the molecular dynamics simulation. Results show that the size effect of the plastic deformation is based on different plastic carriers, suc...

Lasers are widely used in industry as cutting tools due to ultra flexibility of the cutting conditions, obtaining high quality end product, quick set up, non-mechanical contact between the workpiece and the tool, and small size of the heat affected zone. In the present study, laser gas assisted cutting process is examined. Statistical method based on factorial analysis is introduced to identify...

Abstract The article aims to analyze the orthogonal milling method which can be applied in machining powder high-speed steels. To conduct experiment, BÖHLER S390 MICROCLEAN HSS and carbide insert cutters were selected. A turning center with a driven tool was used. examine temperature cutting zone, mathematical model of an turn-milling process developed optimal data chosen using results simulati...

The chamfer enhances the performance of the tool by strengthening the edge and reducing the possibility of tool wear and breakage. The strength of the chamfered tool can be investigated by analysis of process variables. This research investigates the effects of chamfer width and chamfer angle on process variables (force, stress, tool temperature and tool stress) in machining of a mild carbon lo...

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...

Cropping is a cutting process whereby opposing aligned blades create a shearing failure by exerting opposing forces normal to the surfaces of a metal sheet or plate. Building on recent efforts to quantify cropping, this paper formulates a plane strain elastic–plastic model of a plate subject to shearing action by opposing rigid platens. Shear failure at the local level is modeled by a cohesive ...
