Research Summary
- Machining: Development of standard machining experiments for machinability tests. Application of transmission and scanning electron microscopy (SEM) to machining of metals.
- Developed techniques for in situ machining inside a SEM and examination of metal deformation using HVTEM. Performing diamond cutting experiments in the 60's and 70's. Developed theory for fundamental stucture of metal cutting and dislocation theory of flow stress.
- Diamond Machining: Developed methodology for measuring cutting edge radius of steel, glass, and diamond cutting tools. Performed micromachining experiments in single and polycrystalline f.c.c. metals.
- Surface integrity: Correlation of surface finishing processes with residual sresses and fatigue life.
Manufacturing systems:
Evolved stratergy for restructuring the factory into a linked-cell manufacturing system capable of (L-CMS) for lean production. Manufacturing and subassembly cells are linked to final assembly with a pull system for material and information control. Critical control functions (Production control, Inventory control, Quality control, Process control and Reliability) are directly integrated into the manufacturing system. * Developed methodology for measuring robotic process capability, ensuring that robot can be used in unmanned manufacturing cell.* Developed concept for self-propelled mobile robot for use in unmanned cells.* Developed concept of decoupler elements for manufacturing and assembly cells. *Funded by NSF.
