Development of job process plan to include operation of lathes, mills, drills, press, and power saws. Planning, laying out, setting up and tool maintenance is included. Emphasis on shop safety and preventative maintenance. Packed with detailed examples and illustrations, PRECISION MACHINING TECHNOLOGY, Third Edition, is your ideal introduction to today's machine tool industry, equipping you with a solid understanding of fundamental and intermediate machining skills. The text continues to emphasize safety throughout, and it includes thorough coverage of a wide range of topics, including job planning, benchwork, layout, drill press, lathe, milling, grinding, and CNC. In addition, a companion Workbook and Shop Manual include review material to help you master key concepts, along with guided practice operations and hands-on projects using a wide range of machine tools to pave the way for NIMS credentialing success. We will take the information we learned in basic machine shop and go further into what you can do on the machines, such as multiple lead thread cutting, setting tapers, using radius cutters on the lathe and milling machine. We will learn about different metals we may machine and how they affect tool clearance, wear, and sharpening techniques.

1. Cell Phone Policy - Please place Cell Phones out of sight and on mute during class so it does not disturb other students. Let me know if you must take or make a call, then please step out of class to do so and return to class.
2. No eating in shop area.
3. Treat one another with respect, no hazing, harassing, badgering, or improper speech.
4. Turn in work on time, for every unexcused day that it is late you will be docked 5 points on that assignment.
5. Use gloves and face shield when operating grinders or handling dirty items.
6. Never use gloves on any of the other machines in the shop.
7. Safety glasses and ear plugs must be worn when operating machines.

As class attendance is crucial to making a passing grade, after 5, 7, & 9 class periods have been missed; a letter grade will be dropped after each and after 11 missed class days a failure will be recorded for the overall grade. After the class period begins, you will be counted tardy unless there is a recognized excuse.

Sleeping in class will be discussed in an after class meeting with me. Class absences can also have recognized excuses, with each being handled on a one on one basis with your instructor. Do not forget that attendance is 20% of your grade

Student Success
