Demonstration Summary• STEP-NC is easy to implement

– Basic prototype in 4 weeks– Level 2 by adding CAD geometry

• Machining benefits– CNC independent tool paths– Collision detection on the control– Feature based re-programming– Visual closed loop programming

• Enterprise benefits– Long term data retention– Interchange with suppliers


Demonstration Attendees


Plans for Hershey

• Regular meetings on October 23 and 24• Implementor’s Forum Wednesday October 25• T24 Site Visit to Harley Davidson (Evening)• Joint meeting with SC1 on October 26

(Tentative)


Hershey Implementor’s ForumWednesday October 25

• Morning – Inspection and Machining– Aerospace part and automotive part– Videos of machining the parts– Videos of inspecting the parts

• Afternoon – Forum Discussion– Identify gaps– Actions for emerging standards– Actions for existing standards– Strategy for global acceptance


Plans before Hershey

• Deliver IS of AP-238 to ISO• Complete DIS ballot for AP-219• International Interoperability Testing


International Interoperability Testing

• AP-238 CC1 (Toolpath Programming)• Phase 1 (July – August 2006)

– Determine participants– Gather test files– Finalize implementation guidelines

• Phase 2 (September – October 2006)– Implement AP-238 CC1 export for CAM– Implement AP-238 CC1 converters for CNC– Verify using CNC simulators at Hershey meeting
