the new non-conventional cutting process by the use of thermal shock is a convenient procedure for cutting the brittle materials such as glasses and ceramics. this method is based on the application of localized thermal shock to brittle materials by the use of hot air jet, which induces thermal stresses at the tip of an existed pre-crack. due to the thermo-elastic behavior of materials, the pre...

Most integer programming problems can be formulated in several ways. Some formulations are better suited for solution by exact methods, because they have either (i) a strong LP relaxation, (ii) few symmetries in the solution space, or both. However, solving one formulation, we can often branch and/or add cutting planes which are implicitly based on variables of other formulations, working in fa...

This paper systematically describes an interactive dissection approach for hybrid soft tissue models governed by extended position-based dynamics. Our framework makes use of a hybrid geometric model comprising both surface and volumetric meshes. The fine surface triangular mesh with high-precision geometric structure and texture at the detailed level is employed to represent the exterior struct...

Groove is a key structure of high-performance integral cutting tools. It has to be manufactured by 5-axis grinding machine due its complex spatial geometry and hard materials. The crucial manufacturing parameters (CMP) are wheel positions geometries. However, it challenging problem solve the CMP for designed groove. traditional trial-and-error or analytical methods have defects such as time-con...

Abstract Slope is a land surface that has certain angle of inclination in the horizontal plane. The existence slope causes forces push so soil at higher elevation to move. If movement not resisted, may collapse. purpose this analysis determine effect sheet piles where position and depth piles, ground water level earthquake factors on stability excavation slopes infrastructure project Karawang N...

Estimation and modeling of soft tissue deformation during cutting is important for developing a reality based haptic interaction model for surgical training and simulation. In this paper, we are interested in understanding the effect of parameter changes, such as the cutting speed and the angle of cutting, to develop a predictive model that is self consistent with the experimental observations....

This article reports the effects of various artificial aging methods and lubrication modes (dry, mist, wet) on the recorded cutting forces and chip morphology in drilling Al-Si-Mg (A356) cast alloys. In the course of this work, the work part sampled were as-received alloy (T0), solution heat-treated alloy (SHT) and then aged alloys at 155°C, 180°C, and 220°C (T4, T6, T61, T7), respectively. The...
