Assignment 1: Using CAM and Smart Systems in an Engineering Business

A written assignment for which learners produce a report detailing the benefits of CAM to a modern manufacturing business and the use of simultaneous engineering.

This assignment covers the assessment criteria for:-

P1 Explain how the use of a CAM system can benefit the operation of a manufacturing business

P2 Describe the strategies used in simultaneous engineering

M1 Describe the criteria used to assess the viability of introducing CAM and simultaneous engineering systems into a business

You will support your assignment with evidence taken from published case studies relating to well known companies (e.g. Toyota (Futaba), CSM Sheetmetal, Leyland Trucks, BAE Systems, Jaguar and Airbus Industries) which you may have visited

It is important you demonstrate a good understanding of the reasons why, in a customer driven, global market environment, a manufacturing company can survive only if it uses smart systems in the operation of its business.

Using your understanding from the visit to an engineering company which has moved to using world class manufacturing systems would be a good way of gathering research information.

To enable you to have sufficient access to research for this assignment we will be covering the following topics /objectives in our whole-class teaching:

← The use of CAD in terms of its industrial use modifying and producing designs and working drawings.

← The use of CAM for generating part programmes and scheduling materials

← The use of linking software and universal and propriety formats describe and demonstrate the use of CAD/CAM software and explain the benefits.

P1 Explain how the use of a CAM system can benefit the operation of a manufacturing business

To satisfy these criteria you must include reference to the following areas of study:-

Benefits of CAM:

a) Increased profitability

I. Why does CAM have reduced machine set-up times

II. Why do computer aided systems have greater flexibility in terms of batch sizes?

III. How by purchasing CAM systems can it lead to having a reduction in lead times?

IV. What effect do CAM systems have on labour requirements? What is the effect on the reduction of labour costs?

V. How can investing in CAM systems can it result in lower part unit costs?

VI. How can a company optimise the use of the cutting tools used on a CAM machine?

VII. How can some CAM machines assist in the production of complex shapes

b) Improvements in quality

I. How can investing in CAM is there a reduction or elimination of human error?

II. How can a company use CAM to produce consistent accuracy of parts / assemblies

III. Quality assurance methods in production, standardisation of sizes/parts)

c) Greater responsiveness to the requirements of the customer

(e.g. Responding to quotations, modifications of existing products, design changes, batch production of products, making archived products)

d) Competing in the world market place

(e.g. Global competition, clients being able to swap/change suppliers of parts, labour costs in other countries, services (gas/electric prices), recognition of company across the world, using the internet to promote a business/ service

P2 Describe the strategies used in simultaneous engineering

To satisfy these criteria you must include reference to the following areas of study:-

Simultaneous engineering:

1. Parallel operation of tasks

(e.g. concurrent engineering, designing, planning, tooling, all being performed simultaneously during the development of new products)

2. Multi-discipline team-based working

(e.g. marketing, design, modelling, rapid prototyping, manufacturing, development)

3. Time-based management

(e.g. integration of activities, lean manufacturing, total quality management (TQM), shorter development times)

M1 Describe the criteria used to assess the viability of introducing CAM and simultaneous engineering systems into a business

M1 builds on P1 and P2. To achieve it there should be evidence of thought having been given to the pressure on design and manufacturing engineers to optimise resources and use business improvement techniques.

This answer might include responses from your site visits.

It should present the reasons WHY a company would introduce CAM and simultaneous engineering into their business

• Cost

• Workforce demands

• Effect on the overall production time

• How much it will improve the effectiveness of the business
