This paper aims to investigate the cutting behavior of optical glassy polymers in order to identify the shape defects induced by the micro-machining processes.
Polycarbonate (PC), Allyl Diglycol Carbonate (CR39), and polythiourethane (MR7) polymers are considered in this study to perform micro-machining experiments using the orthogonal cutting confi...

AbstractSAF2205 bidirectional stainless steel is an excellent material for multiple corrugated diaphragms. It is necessary to study its stamping forming characteristics and provide a theoretical basis for stamping forming of multiple corrugated diaphragms. In this paper, the detailed V-bending process parameters are formulated. The effects of bendi...

In the study conducted for this contribution, sheet material 4 mm thick, non-heat treated (II), normalized (NH) and tempering heat treatment implemented (TH), were formed at a bending angle of 90°. As a result of the forming process, the effects of the R2, R3, R4, R5, and R6 mm punch tip radii on spring back and spring go values were investigated. ...

With the development of technology, semiconductor components are now being used in many parts of IT components and solar modules. Because of the features of these products, a device for inspecting the manufactured products is needed. In this paper, we present a method of manufacturing a probe for use in testing semiconductor-based products. As a fe...

Hull structures and offshore structures are composed of curved thick plates. Line heating method has traditionally been used to produce such curved plates. However, it is recognized that the hot-forming process causes a variety of issues on doubly or multiple curved plates. A multi-point forming mechanism with square press heads is a new forming pr...

This study presents a quantitative sensitivity analysis for the assessment of fiber reinforced composites (FRCs). Global sensitivity analysis (GSA) approach is based on the variance based method incorporating Random Sampling-High Dimensional Model Representation (RS-HDMR) expansion in which component functions are determined by diffeomorphic modula...
