Presentation Transcript

  1. Machining and Design for Manufacture

  2. Basic Machinery • Straight line cuts • Rectangular work pieces • Boring/Radial Cuts • Axisymmetric work pieces

  3. Basic Machinery • Square material • Rough cuts • Round material • Rough cuts

  4. Machinery tips/tricks • Ask about feeds/speeds for each machine and material • Or calculate them, and check with John/Adam or TA • Zeroing machines • Threading on Lathes • Automatic feed • Tool changing • Small, slow final passes increase surface finish • Climb/Down milling • Material Size limits • Take your time • Allot at least an hour or two • Remember clean up time

  5. Tools • Calipers: low precision measurement tool • Mic/mike/micrometer: High precision measurement tool

  6. Reading a ‘Mic’

  7. Lingo • Thousandths • .001” • Basis of all machining measurement • .0001” is called a thenth! • CNC • Computer Numerically Controlled • Pecking • Repeatedly making small drilling cuts • Turning • Machining on a lathe • Deburr • Remove rough edges

  8. Safety • Don’t leave drawers open • Don’t leave tools out • Don’t walk away without turning the machine off: E-stop • Close toed shoes • No loose jewelry or clothes, long hair tied back • Safety glasses • No gloves • WHEN IN DOUBT, ASK!

  9. Design for manufacture • Material considerations • Metal vs plastic vs wood • Type of metal • Machinability • Soft is easy, hard is… hard. • Piece geometry vsworkpiece • Material waste! • Square vs round • Cast vs billet • Complexity • Fillets and bevels are your friend! • Tolerancing

  10. Design for manufacture • Straight line approaches! • Interior cavities/ overhangs • Hardware lengths (bolt accessibility) • Interior right angles • Self questioning • How will I get a tool in to work this? • Standard size holes/threads • Ask a shop worker • Ask me • Practice and observe!

  11. Resources • MET/MFET • Have a casting lab • Additional machines • Michael Golden Labs (MGL) • AFL-Basement of ARMS • Lots of CNC automation • Plasma cutter
