A Study of Economical Machining: An Analysis of the Maximum-Profit Cutting Speed

Abstract

Apart from the conventional theory of the minimum-cost or maximum-production cutting speed, a new concept of the machining conditions for maximizing the profit for the manufacturing enterprise was presented. A Concept of the Maximum-Profit Machining ConditionsGilbert""" and other investigators analyzed the machining conditions for the minimum-cost per piece of products, especially the minimum-cost cutting speed. At this speed, the production cost per piece including idle and loading costs, cutting cost, tool changing cost, tool cost, tool regrinding cost, etc., is minimum, * Department of Precision Engineering.

Optimizing machining economics models of turning operations using the scatter search approach

“…Earlier studies (Okushima and Hitomi 1964, Ermer 1971, Boothroyd and Rusek 1976 were limited to single-pass turning operations without consideration of any constraints. It is now evident that various machining constraints should be satisfied in actual manufacturing applications.…”

Development of hybrid predictive models and optimization techniques for machining operations

“…Traditional approaches in machining optimization have been limited to objective functions related to cost or productivity [24][25][26][27]. Although such an objective is desirable, the more critical role of optimization lies in the need for optimizing the various machining performance measures for higher productivity and enhanced product quality.…”

“…Early efforts on machining optimization methods are largely based on the traditional low cost or high productivity criteria. A large domain of published work found in the literature shows the continued and extensive attempts to develop various optimization techniques for machining processes during the last three decades [24][25][26][27][28][29][30][31][32]67,68]. Most commonly considered optimization objectives include production time, machining cost, profit rate, material removal rate, a combination of these, and tool usage.…”

Contour finish turning operations with coated grooved tools: Optimization of machining performance

“…Gilbert (1950) considered two criteria, maximum production rate and minimum cost, in order to determine the appropriate cutting speed for machining operations. Okushima and Hitomi (1964) considered maximizing the profit rate in machining processes. In a similar manner, but more practical condition, Tee et al (1965) produced an analysis by employing a computer to search for the condition yielding maximum rate of profit.…”
