Abstract

This work is intended to explore details of CAD/CAM techniques and to check its application in medium size industry. To achieve this goal, a thorough study has been carried out on current CAD/CAM techniques, keeping in mind it's requirements, source and application, considering both the hardware and software side of it. To check application of CAD/CAM in an industrial environment, Schering Plough corporation was chosen as a subject. The main theme behind this application to the Schering Corp. was to develop the CAD/CAM capability within company, in order to gain better control over the quality and productivity, and to reduce dependence on the vendors in areas of design, analysis and machining.

The packaging line of this company was completely analyzed and bottlenecks in production were highlighted. One of the major problems with the packaging line was a jam up of the transfer-bucket system on the cartoning machine. With the help of three dimensional CAD software, a new bucket system was designed. Through a CAD/CAM link (DXF) this design data were transferred to CAM software. The CAM software simulated the tool path for machining operations, and NC codes were generated for the designed components. The software used included SDRC-IDEAS, Auto CAD and Smart CAM. The Work station used was a SUN 3/60 in a UNIX environment. This work will help to replace the existing transfer bucket system by the system of new design for better productivity. This work will also help in the selection and implementation of a CAD/CAM system for the company's specific needs, and the application presented will help to understand how it works.
