Precision Machinists CNC Machining Process Video 4

Closing in on the finished products for this Precision Machinists reproduction of a clients original electric connector. CNC Cad/Cam Software and the CNC Lathes and Mills are a cost efficient way to create reproducible parts that need regular replacement. Of course precision machinists can also create parts and complete projects from prototype to production (pro2pro for short). A precision machinist is as much an artist and creator as a skilled machinist and programmer. The CNC Precision Machinists job requires he or she is able to tap his vast reserves of creativity, problem solving, trouble shooting, programming skill and understanding of the capabilities and limitations (few) of his CNC 4 Axis Lathes and Mills. All the while keeping the ultimate use in mind and a watchful eye on quality. After viewing these videos you should have a good understanding of how the Precision Machinists in your area can help solve your part and project requirements

Grinding a cam for a model internal combustion engine can be a tough job. Using a computer controlled cam grinder is an attractive alternative to hand filing cam lobes, assembling multipart camshafts or building a complicated mechanical grinding machine. Joe Martin has created a CNC (Computer Numeric Control) cam grinder using mostly off-the-shelf Sherline machine tool parts along with a g-code program he developed himself. This video details the production of a cam for a Howell V-4 engine being produced by the Joe Martin Foundation Craftsmanship Museum. To learn more about the engine itself go to www.CraftsmanshipMuseum.com/HowellV4.htm. For more about Sherline miniature machine tools visit www.sherline.com. This is part two of the video. Each half is about 9 minutes long.
