Analysis for the Manufacturability of Mechanical Parts and its Functionality

Abstract

There is always a gap between manufacturing sector and designer. Designer creativity fails at the shop floor due to manufacturing constraints. In traditional design process designer designs a product and it goes to the shop floor for production. In most of the cases either designer has to redesign the product or manufacturing engineers modified the design as the designer creativity cannot be manufactured due to manufacturing constraints. There is no reconciliation of process capabilities with design requirements. It will consume a lot of time to launch the product, which increases the lead time and also consume some revenue. Design for manufacture the methodology through which products are designed by taking manufacturing constraints in mind during design stage to reduce the lead time. Those who reduced the lead time will capture the market. In this paper an effort has been made for computer aided design for manufacture tool which can help the designer to improve the quality and design of the product at early stages .With this tool we can decide at early stage that whether this product is manufacturable with present manufacturing operations. After evaluating the manufacturability, designer may have more than one option i.e. there are different ways to manufacture it but he has to suggest the best without effecting the quality and cost. Designer can check its functionality by comparing it with the features of the rival products. Most of the products fail to satisfy the customer in terms of its function, cost and quality as the customer always wants more features with same price and quality i.e. designer creativity should match the customer’s requirements with respect to its functionality also. This tool will provide enough information to the designer about the manufacturing constraints, dimensional constraints, and their functionality.
