• Monitor and verify micro-inch surface finishes (Ra) using profilometers
• Select, mount, and balance appropriate grinding wheels (Aluminum Oxide, Silicon Carbide, or CBN) based on material specifications
• Perform wheel dressing and truing to maintain form, finish, and dimensional accuracy
• Develop, modify, and optimize CNC programs using Fanuc or OEM programming software
• Perform geometry and thermal offset adjustments on CNC controllers to correct wheel wear and material changes
• Optimize grinding parameters to balance surface finish, cycle time, and wheel life
• Lead or drive process improvements to reduce setup time, cycle time, and scrap
• Interpret complex blueprints and GD&T with multiple datums
• Perform in-process and final inspections to ensure conformance to the drawing
• Train and mentor other operators across the CNC and manual grinders
