Investigation into Engineering Ceramics Grinding Mechanism and the Influential Factors of the Grinding Force
The grinding force is a key parameter in the grinding process, which is closely associated with the grinding mechanism of engineering ceramics, microstructure and properties of ceramic materials, and the selection of grinding parameters. Meanwhile, it is also a key indicator to assess the grindability of a material. The grinding force is a crucial parameter to reflect the grinding process, whic...

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Effect of amount of grinding on flexural strength of dental ceramics.
The aim of this study was to determine a suitable amount of grinding of a flexural test specimen for clinical evaluation of dental ceramics. Three dental ceramics (Crys-Cera, OCC and IPS Empress Cosmo) were selected. Five types of bar-shaped patterns were prepared for a three-point bending test, and four types of disk-shaped patterns for a biaxial flexural test. Ceramic specimens were fabricate...
متن کاملInfluence of grinding procedures on the flexural strength of zirconia ceramics.
The surface of zirconia may be damaged during grinding, influencing the mechanical properties of the material. The purpose of this study was to compare the flexural strength of zirconia after different grinding procedures. Twenty bar-type zirconia specimens (21 x 5 x 2 mm) were divided into 4 groups and ground using a high-speed handpiece or a low-speed straight handpiece until the bars were re...
متن کاملPrediction of steel machinability by genetic programming
Purpose: This paper describes intelligent system to predict steel machinability. Design/methodology/approach: The prediction of machinability of steel, depending on input parameters (percentage of calcium, percentage of oxygen, percentage of sulphur), was performed by means of genetic programming and data on the batches of steel already made. Findings: The mathematical model to predict machinab...
