  4. Quick Index Of Techniques Preparation & organization Cutting tools (MC) Program development • Spot disorganization • Well designed work area • Improving personnel utilization • Documentation issues • Programming versus setup time • Job order planning • Kitting • Non-production time • Standard tool stations • Consolidate cutting tools • Removing/replacing tools • Assemble tools off line • 2 ways to use length comp • Measuring off line • Multiple identical tools • Presetting certain tools • Program for setting offsets • Tool length measuring probes • Program to measure lengths • Taper reamers • Part families Program transfer • PC based controls • Background edit • Manual DNC system • Automatic DNC system Program verification • Two-part definition • Proven jobs • Tool path plotters • Off line verification • Trial machining • Presetting tools • Programming trial machining • Trial boring • Trial turning • Changing machining order Workholding setup (MC) • Multi workholding devices • Qualified setups • Making use of sub-plates • Changing parameters • Pallet changing systems • Suggestions for facilitating Cutting tools (TC) • Standard tool stations • Tool nose radius comp offsets • Assemble tools off line • Quick change tooling Workholding setup (TC) • Clamping pressure • Reuse soft jaws • Tailstock • Changing parameters • Removing workholding device • Mounting jaws • Quick jaw change chucks • Chucking rings • Chucking tool • Machining soft jaws • Jaw boring custom macro Assign program zero (MC) Program optimizing • Qualifying setups • Calculating assignment values • Measuring first time • Programming entries • More on sub-plates • Spindle probe • Using edge finder as probe • Effects on setup time • CAM systems and optimizing • Tool path plotters • Variables for cutting conditions Click on a topic! Assign program zero (TC) • Geometry offset usage • Tool touch-off probes

  5. Two Task Types Related To Setup

  6. On-line tasks: Tasks done while the machine is down between production runs Off-line tasks: Tasks done while the machine is in production for the next (or some future) setup Two setup-related task types: Setup time is the sum-total of all on-line tasks!

  7. Two setup-related task types: Tasks commonly done while the machine is down • Tear down old setup & put everything away • Clean machine • Make new setup • Cutting tool tasks • Assemble, measure, and enter offsets for • Assign program zero • Measure position and enter fixture offsets • Load program • Verify program • Optimize program The fewer the people in the CNC environment, the more tasks tend to be done on line
