CAD CAM Engineer CNC Granite Machining

Scope of Work :

The CAD / CAM Engineer will be responsible for the entire digital fabrication pipeline , covering :

• 2D Drawing Interpretation & 3D Conversion
• Import, clean, and prepare 2D architectural or sculptural drawings (DWG / DXF / PDF).
• Generate accurate 3D CAD geometry (solid / surface / mesh) suitable for stone machining.
• Convert conceptual sketches, hand drawings, or photographs into 3D models.
• Align all models to Vasthu-based coordinates, datum, and reference axes.
• 3D Sculpting & Detailing Preparation
• Collaborate with STL artists and sculptors to refine organic or figurative forms.
• Optimize mesh geometry, correct topology, and prepare STL / OBJ files for CAM readiness.
• Ensure seamless continuity between adjoining components (columns, beams, panels, etc.).
• CAM Programming & Toolpath Generation
• Develop multi-axis toolpaths (3-axis, 4-axis, 5-axis) for all machining stages :
• Roughing / Semi-finishing / Finishing / Polishing / Engraving.
• Simulate machining operations, avoiding collisions or gouges.
• Post-process verified G-code compatible with CNC controllers (Fanuc / Siemens / Syntec).
• Calibrate tool offsets, wire saw parameters, and spindle feeds to match granite density (Mohs 6–7).
• Machine Integration & Execution Support
• Coordinate with CNC operators for setup, fixturing, and block orientation.
• Validate output dimensions, surface accuracy, and artistic detailing.
• Adjust feed rates and coolant flows for tool life and finish optimization.
• Document tool libraries and machining parameters for repeat jobs.
• Quality, Documentation & Data Management
• Maintain CAD / CAM file archives with proper revision tracking and metadata.
• Generate setup sheets, toolpath documentation, and machining time estimates.
• Maintain compliance with MAMAT standards for accuracy (±1 mm) and repeatability (≤ 0.5 mm).
• Collaborate with QA and structural teams to validate as-built geometry.
