Mathematical Modeling of Metal Cutting Process
In the practice of metal treatment by cutting it is frequently necessary to deal with selfexcited oscillations of the cutting tool, treated detail and units of the machine tool. In this paper are presented differential equations with the delay of self-excited oscillations. The linear analysis is performed by the method of D-expansion. There is chosen an area of asymptotically stability and area...
متن کاملIdentifying Method for Key Quality Characteristics in Series-Parallel Mul- tistage Manufacturing Process
Many actual multistage manufacturing processes are not serial structure, but parallel structure or hybrid structure. The quality relationship model for multistage manufacturing process with parallel structure was developed based on state space model. The quality relationship model of multistage manufacturing process with hybrid structure was developed via the hierarchical iteration method based...
متن کاملInvestigations of Process Damping Forces in Metal Cutting
Using finite element software developed for metal cutting by Third Wave Systems we investigate the forces involved in chatter, a self-sustained oscillation of the cutting tool. The phenomena is decomposed into a vibrating tool cutting a flat surface work piece, and motionless tool cutting a work piece with a wavy surface. While cutting the wavy surface, the shearplane was seen to oscillate in a...
متن کاملA fuzzy reliability model for series-parallel systems
Fuzzy set based methods have been proved to be effective in handling many types of uncertainties in different fields, including reliability engineering. This paper presents a new approach on fuzzy reliability, based on the use of beta type distribution as membership function. Considering experts' ideas and by asking operators linguistic variables, a rule base is designed to determine the level ...
متن کاملSimultaneous Optimization of Production and Quality in a Deterioration Process
Achieving optimal production cycle time for improving manufacturing processes is one of the common problems in production planning. During recent years, different approaches have been developed for solving this problem, but most of them assume that mean quality characteristic is constant over production run length and sets it on customer’s target value. However, the process mean may drift from ...
