1 Read and translate the text Computer-Aided Process Planning. Make up the plan in form of questions, render the text. Computer-aided process planing

Detailed planning is needed in order to implement a successful computerized manufacturing project. Once a design is finalized, an engineer prepares a detailed process plan. The plan comprises step-by-step instructions that include how to set up equipment, how to make a part, and last but not least, how to assure quality by inspecting the part after it is made. Routings between equipment workstations must also be determined. The plan is usually supplemented with drawings of the tools necessary to make the part and detailed instructions about how to operate the tools. Process planning is a tedious and time-consuming job. In a manufacturing environment, where it is always desirable to reduce time from idea to finished product, the computer-aided process planning (CAPP) can speed up the planning process and help ward off the competition.

There are two approaches to computer-aided process planning: variant and generative. The variant CAPP system is based on parts classification. As in biological classification, parts to be manufactured are combined into families. Parts that belong to a certain family have similar shapes, attributes, and parameters. One drawback of the variant CAPP is that the generic family process may not be suitable for a particular new part.

The generative CAPP system does not have this drawback because it is based on an entirely different principle than variant CAPP. Instead of retrieving a generic family process and editing it, a process plan is created from scratch by using a set of decision rules that define the selection of proper operations, the sequence of operations, the treatments, the tools, and the delivery routes to be used in creating the part.
