2-3 Objectives The various types of jobs available in the metal-working industry The type of work each job entails

2-4 New Technologies Tool that makes it possible to produce better quality goods at lower prices Continually changing and improving Doubling every three to five years Training can make difference between success and failure Industrial workers and students must prepare for continual education to survive

2-5 Technology Curriculums Imperative for educators to stay abreast of new improvements and manufacturing processes Educators must continually introduce new material into curriculum Old “time-proven” methods and processes have been outmoded

2-6 Technology Courses Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display.

2-7 Modular Training System Consists of individual modules that can be readily incorporated into tech curriculum Main areas of modular training system –Conventional machining –CNC machining –CAD/CAM techniques –Quality control –Maintenance –Automation –Flexible manufacturing

2-8 Apprenticeship Training Apprentice employed to learn trade under guidance of skilled tradespeople Joint agreement –Sponsoring apprentice company –Dept of Labor Federal Bureau of Apprenticeship –Trade union To qualify: completed high school program, good standing in math, science, writing skills and mechanical drawing Wage scale increases periodically during program Certificate granted upon completion, qualifies then for journeyman status in the trade

2-9 Machine Operator Classified as semiskilled tradespeople Rating of A, B, C with A the more skilled Class A skills –Make necessary machine setups –Adjust cutting tools –Calculate cutting speeds and feeds –Read and understand drawings –Read and use precision measuring tools Jobs minimized with advancement of robots

2-10 Maintenance Machinist Needs combination of mechanical, rigging and carpentry skills Apprenticeship usually ranges from 2-4 years –High school graduate –Good technical training General knowledge of electricity, carpentry, sheet metal and machine tool trade

2-11 Machinist Skilled workers who can efficiently operate all standard machine tools Have thorough knowledge of metallurgy and heat treating Have basic understanding of welding, hydraulics, electricity and pneumatics Be familiar with computer technology

2-12 Types Of Machine Shops Maintenance shop –Generally makes and replaces parts for all types of setup and cutting tools and production machinery Production shop –Makes many types of identical machined parts, such as pulleys, shafts, bushings, motors, etc. Jobbing shop –Required to do variety of tasks (usually under contract to other companies)

2-13 Job Classifications Technician –Works at level between professional engineer and machinist –May assist engineer Technologist –Works at level between graduate engineer and technician –3-4 year graduates from technical college Physics, advanced math, chemistry, graphics, computer programming, business courses

2-14 Job Classifications Engineering technologist –Do many jobs normally performed by an engineer –Often employed in middle management Tool and Diemaker –Highly skilled craftsperson able to make different types of dies, molds, cutting tools, jigs, and fixtures –Serve an apprenticeship, have above-average mechanical ability, operate all standard machine tools

2-15 CNC Machine Operator/Programmer Duties vary from shop to shop Skills include how to: –Visualize a CNC program –Understand machining processes and the sequence of operations –Make machine setups –Calculate speeds and feeds –Select cutting tools

2-16 CNC Machine Programmer Duties vary from shop to shop Skills include how to: –All the skills of a CNC machine operator –Be skilled in print reading –Have a good knowledge of computer programming languages and procedures –Be able to visualize machining processes and operations

2-17 Quality Control Inspector Checks and examines machined parts to determine whether they meet specifications Have technical or vocational education Skills necessary –Understand and read mechanical drawings –Make basic mathematical calculations –Use micrometers, gages, comparators, and precision measuring instruments

2-18 Instrument Makers Highly skilled tool and diemakers working directly with scientists and engineers Have more training than machinist or tool and diemaker Must work to closer tolerances Generally serve 4-5 years apprenticeship

2-19 Professions Many areas open to engineering graduate –Bachelor’s degree in engineering –Specialize in specific engineering discipline Industrial, Metallurgical, Aerospace Mechanical, Electrical, Electronics Technicians becoming more plentiful –High school diploma, plus 2 years higher ed –Usually trained in one area technology

2-20 Trade Organizations Help members stay abreast of changes Implement new manufacturing technology in order to stay competitive in the world Two major machine tool related organizations –AMT Association for Manufacturing Technology –SME Society of Manufacturing Engineers

2-21 Association for Manufacturing Technology (AMT) Formerly the National Machine Tool Builders’ Association Nonprofit trade association representing US Supports extensive scholarship program for technical training Provides machines, tools for young machinists to compete in VICA Develops effective training procedures and textbooks

2-22 Society of Manufacturing Engineers (SME) International society dedicated to advancing manufacturing profession Over 80,000 members throughout world Sponsors ~300 student chapters with over 9000 members in community colleges and technical schools Storehouse for up-to-date technological knowledge
