13 Practical Machining Projects for Students and Beginners

If youre teaching a course on machining, it might be cool to start on the clamps early on, and then later on make the vee blocks as a separate project. That way the students can be challenged at their skill level for both aspects of the project.

Can you anneal 4340? - The Home Machinist!

Mar 16, 2008 · The Home Machinist! Annealing would make the 4340 steel more ductile- more difficult to machine, stringy chips similar to 304 ss. Hardining actually makes it better to machine, if its not hardened too much. Running the lathe or mill faster and using carbide produces a good finish on nhardened/unannealed 4340. Thinking of a model cannon Comparative Assessment on Machinability Aspects of AISI May 14, 2016 · This paper compares the performances of uncoated carbide and coated cermet inserts for varied machinability aspects throughout the machining of hardened steel (AISI 4340, 48 HRC) in the dry cutting surroundings. Cutting speed, feed, and depth of cut were thought of as major governing parameters. Workpiece surface temperature, machining forces, and tool flank wear were taken as

How To Machine Crankshafts - Model Engine News

Heat-treating causes distortion, requiring that the shaft be finished oversize, then ground to final size and alignment. For 'soft' shafts, the best choice of material is "stressproof" steel, if you can get it. This machines ok with sharp tooling. Good old 12L14 makes machining the shaft a joy, but it's a bit soft, especially for larger engines.
