遼字石油化工大學⊙ 6.1 Manufacturing process AImportant concepts 1. Process of product: Manufaturing is the utilization andmanagement of materials, people, equipment, and money to produce products. For successful adn ecomomical manufacturing to be achieved, lanning must start at the design stage and continue through the selection of materials, processes, equipment, and the scheduling of production 2. Process of Part: The Process by which the shape dimensions and performance of raw material or rough casting are changed directly by mechanical manufacturing into desiged parts is called component manufactured part production, or process route

Operations: When one operator or a group of operators) works in a definite position (one machine tool or clipping table )to achieve the continous manufactruing of one or several parts simultaneously. An operation is the basic element of process procedure as well as of the production schedule and of cost estimation 200 Example1 B,s30 590 Fig. 6. 1 the engneering drawing of a shaft
