VICA CNC Programming Guide covers the basic CNC principles and gives detailed explanation of each step in the programming and turning a part. The time and money spent to prepare and distribute this Guide will be wasted unless the metalworking/ manufacturing teacher is committed to introducing CNC as part of the curriculum. The following suggestions can be used to introduce CNC theory and technology to metalworking/manufacturing courses: 1. Teach the basics of CNC using the VICA CNC Programming Guide that should be supplemented by a textbook, visuals, videotapes, etc. - COST approximately $200.00. 2. Use the VICA CNC Programming Guide and textbook along with CAD/CAM software that allows a student to simulate the machining of a programmed part on the computer screen. - COST approximately $600.00. 3. Use the VICA CNC Programming Guide, textbook, CAD/CAM software, plus a CNC Bench-Top teaching size machine. This is by far the best method since students can actually produce a real part that they can hold and take home to show their parents. - COST approximately $6,000.00 For more information from a leader in CNC educational courseware, software, and Bench-Top Teaching machines contact: Denford Inc. 1-800-886-9750 www.denford.com E-mail: sales@denford.com The old argument that there are still many shops using old technology is a fallacy used consciously or unconsciously by those resisting changes. Over 90% of the machine tools manufactured in the world have some form of CNC control, therefore conventional (manual) machines should be used to provide only the basic knowledge of machines and machining processes. 5
We must all do our part; State Directors, District Directors, School Administrators, and Classroom Teachers to correct a problem long overdue in technical education. Steve Krar CNC Team Leader Precision Machining Technology 6
