Program for Structural Synthesis of the Multiple Fixtures
نویسندگان
چکیده
This paper presents a program for structural synthesis -conception and design work-of the multiple fixture devices in the machine-tool structure. This program was created according to the principles of object-oriented programming. The program is also built upon two fundamental principles which characterize the evolution of the systems: the combination and the selection. The basic structural elements of the fixture devices are the clamping mechanisms. For this reason the program accomplishes clamping mechanism combinations, obtaining mathematically-possible combinations from which the combinations of technical incompatibility are excluded. Finally, the paper presents some fixtures functional structures obtained with the proposed program.

Exploration of the Customized Fixtures for the Evaluation of Three-point Bending Strength of Dental Resin Composites
Introduction: This study aimed to devise customized fixtures for the evaluation of three-point bending strength (TPBS) of resin-based dental composites (RBCs). Materials and Methods: A cube-shaped jig made out of wood with dimensions of 105×105×101 mm was prepared in this study. A 20-mm-diameter hole was made in the center of the wooden jig. In addition, a stai...

Background and Objective: One of the most concerns about the use of implant treatments is bacterial leakage between the fixture and abutment at the connection. The aim of this study was to evaluate the bacterial leakage rate at the interface of ITI fixtures and ITI, DIO and OSSTEM solid abutments. Materials and Methods: Thirty ITI fixtures were divided into three groups (n=10) based on t...
