7. STEP Tools, Inc. Slide 7© Copyright 2009 — STEP Tools, Inc. Next steps Lessons learned –We need to use chip load to drive speed and feed Feed Speed CAM AP-238 Actual Machine Max Feed and Speed Feed Speed Programmed Machine Max Feed and Speed Programmed No. Flutes Actual No. Flutes

8. STEP Tools, Inc. Slide 8© Copyright 2009 — STEP Tools, Inc. Next steps Lessons learned –We need to change tool dimensions –More data about the tools »Stick–out (holder_base – tool_tip) – LUX in ISO 13399 »Minimum allowable flute length – max_depth_of_cut »Tool holder dimensions –Need more / clearer set-up information »Origin, material »As part of rawpiece definition? –Variable elements that are realistic to change »Utility to extract tool dimensions

9. STEP Tools, Inc. Slide 9© Copyright 2009 — STEP Tools, Inc. Goals for next demonstration What –Enable/Show round trip –Mastercam ->AP-238-> Catia ->AP-238 -> FeatureCAM –Multiple set-ups Use Moldy again –Improve documentation so more can participate »Setup information – annotate origin »Tool stick-out, #flutes, flute length »Max feed and speed »Operation cycles for drilling –Participation Rules »Must be from single STEP-NC data source »Must meet tolerances defined for the part Develop new part – Boxy –Test/Prove-out multiple setup –Accuracy, documentation, canned cycles

10. STEP Tools, Inc. Slide 10© Copyright 2009 — STEP Tools, Inc. Moldy in Bath Faster machining by changing step over Metric – 3 axis Improve portability –Feed speed approximation using spindle power –Eliminate ¾ inch zero radius cutter –Single hole size »Describe most accurate process »Describe required tolerances »Describe process parameters such as peck cycles »One hole size = 0.25 inch aka 6.35 mm »Tell users they can reduce the process if they maintain the tolerances

12. STEP Tools, Inc. Slide 12© Copyright 2009 — STEP Tools, Inc. Boxy in Bath Use multiple CAM systems to make data –Mastercam for setup 1 and 4 –Catia for setup 2 –FeatureCAM for setup 3 Practice multiple setups –Communicate origin to operators –Metric part and tooling –Tolerances on each part for each set-up –Different CAM for each setup –Four setups –No tool larger than 12mm
