Abstract In this work the forging process in step-wedge strikers by commercial FE-code Deform was simulated. For microstructure evolution Cellular Automata method used. The influence of technological and geometric parameters on studied. Models with different values joint angle wedge depression faces, friction coefficient at contact workpiece tool, upper striker movement speed temperature were c...

This paper describes a bone-mountable surgical robot system for hip surgery and its in vitro experiments with cadavers. The system eliminates the need for obtaining CT scan data by adopting gauge-based, bone-mounting registration method and is designed to replace only the broaching procedure, which is !mom to be the most error-prone procedure in the manual surgery. The performance of this syste...

Abstract This paper has two aims. First, I critically discuss Daniel Whiting’s (Philos Stud 195(9):2191–2208, 2018) recent proposal that a reason to ϕ is evidence of respect in which it right ϕ. raise objections against this view: (i) subject modified version Eva Schmidt’s (Ethics 127(3):708–718, counterexample the influential account reasons terms and ‘ought’, and—setting aside judgments about...

Surface conditions produced by manufacturing processes are known to significantly affect the fatigue strength of metallic materials. However, tests on planar specimens usually present onset crack in a specimen edge, where superposition different machining techniques and subsequent operations can hide effects studied process. This study deals with design test able reliably assess high cycle any ...

Cutting processes can be used in batch production of polygonal bars with special features. In this paper, a new form of broaching process for cutting of hexagonal bars from raw round bars is discussed. Due to lack of rolled or drawn raw material, the final product is made of AISI 316L stainless steel bars having appropriate initial size. In this method, a fixed die is used as a tool, and by app...

Electrical discharge machining process is one of the most Applicable methods in Non-traditional machining for Machining chip in Conduct electricity Piece that reaching to the Pieces that have good quality and high rate of machining chip is very important. Due to the rapid and widespread use of alloy DIN1.2080 in different industry such as Molding, lathe tools, reamer, broaching, cutting guillot...
