CAM PROGRAMMING & CNC

This portfolio showcases my self-directed independent projects and hands-on execution in Computer-Aided Manufacturing (CAM) and CNC programming. Backed by formal certification and nearly two decades of mechanical engineering experience, I approach subtractive manufacturing with a focus on toolpath optimization, smart fixturing, and cycle-time reduction from prototype to finished part. Explore the selected projects below to see a breakdown of material selection, machining challenges, and step-by-step technical problem-solving for complex geometries.

Bearing Shoulder Screws

• Hardware / Control: Haas SL-20 Lathe / Proprietary Haas Control
• Software: Solidworks CAD, Handwritten G-Code with Verification in Mastercam
• Material: Cold-drawn 303 Stainless Hex Bar (25HRC)
• Highlights: Multi-step turning, precision bearing shank (-0.0005” to 0.0”), live center support, and optimized feed rate tuning to prevent thread distortion during shoulder grooving.
