CAD/CAM – Illustrated Guide

An Engineer job is to provide a complete solution in his/her area of work by Using optimum Men, Material, Machine, and Money for the comfortable and reliable products to the human society. Faster change of product design for the comforts of the human kind, Leeds to often bottle neck situation to engineers particularly to face the competition, delivery, and quality.

In Recent days more and more companies wanted their technicians and engineers, ready to fit in any work force though they are fresher. So it is becoming great challenges to get the suitable trained manpower in CAD/CAM and allied fields. Many fresh graduates fall in the trap of fake training centers who through false promises. Due to lack of up gradation of our university syllabus system in the subjects like Advance Production Technology, CAD/CAM etc with respect to today’s practical approach, puts a large gap between university and industries in most emerging areas. To address this gap government of India investing huge quantity of money in its establishments in tie-up with many countries/Agencies by bilateral agreements, to supply qualitative trained man power. Adequate measures are taking places through the need based training program by the Government Industry-Institute guiding the industrial society based on imposed challenges in the area of design and manufacturing.

Computer Aided Design is concerned to support the Design Engineering activity, that includes Creation of 2D/3D Geometric Models, Doing Engineering Analysis, Evaluating the Design by simulation and Produce Rapid Drafting for Manufacturing” with help of computer. The Traditional CAD System offers 2D Drafting, 3D modeling with Limited Modification Capability. This System substitute Drafting Board completely.

CAM (Computer Aided Manufacturing) is defined as “the effective use of computer technology in manufacturing planning and control”. Often there is confusion between the term manufacturing and production. Proving the component that is to be produced in large quantity is called manufacturing technology. That mainly includes planning the tools, fixtures, feed, and speed and also Selection of Materials, CNC machine, Program version and capable CAM systems, process planning etc. Once it is proved the component may allot for the production which produce in lots. This includes capacity planning, costing, Time management etc. A typical CAM includes a CAM system, CNC machine with compactable controller DNC link for feeding the program. The CAM job is to generate the program based on the geometric model. DNC job is to communicate the program to the Dummy terminal and to the CNC M/Cs which cuts the raw material to the finished part. The modern CAM system provides 5Axies facility to machine the most intricate parts at one setting. Some CAM system provides color coding for the extra part material that still to be machined.

Computer Integrated Manufacturing is an integrated approach to maintain a Common Database for CAD, CAM and Business control. CIM includes all of the CAD/CAM, R&D, e-Publishing and also embrace the business functions of a manufacturing. CIM implements computer technology in all the operational and information processing activities related to manufacturing.

Product development cycle Reverse Engineering Rapid prototyping Product life cycle management Virtual Manufacturing are emerging trends in CAD/CAM Technologies.

CAD/CAM professionals have fare chance to work at their client place like Australia, Japan, USA, Germany, Switzerland, Italy, and Canada etc, for Industrial giants working on the projects of aerospace, railway and automotive sectors which give more lucrative rewards for CAD/CAM Engineers. A freshly and perfectly CAD/CAM trained Engineer gets fair and handsome salary and with two/three years experienced professionals gets excellent salary.
