Job description

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.

Software Proficiency (Full Pipeline) :

2D to 3D Design Conversion :

  • AutoCAD / DraftSight / BricsCAD – 2D drafting and layout base.
  • Rhino 3D / SolidWorks / Fusion 360 / Creo – for parametric 3D modeling and assembly.
  • ZBrush / Blender / Meshmixer – for organic sculpting, mesh repair, and STL cleaning.

    • Reverse Engineering & Scanning (if applicable) :

  • Geomagic Design X / MeshLab / PolyWorks – for converting 3D scan data into CAD surfaces.

    • CAM Programming & Toolpathing :

  • Autodesk PowerMill / Mastercam / RhinoCAM / WorkNC / Fusion 360 CAM – for generating toolpaths for 3-, 4-, and 5-axis CNC granite machining.
  • Simulation Software : Vericut / NC Viewer / ModuleWorks for collision and kinematic simulation.
  • Post-processing : Controller-specific postprocessors (Fanuc / Siemens / Syntec).

    • File Formats to be Managed :

  • Input : DWG, DXF, PDF, STL, OBJ, IGES, STEP.
  • Output : NC / G-code, CAM setup sheets, simulation files, technical drawings.

    • Qualifications & Experience :

  • Education : Diploma / B.E. / B.Tech. in Mechanical, Mechatronics, Production, or Industrial Design.
  • Experience : Minimum 3–5 years in CAD / CAM programming for stone, marble, or metal machining.
  • Preferred : Experience with granite or hard stone materials and large-format 5-axis macines.

    • Technical Skills :

  • Deep understanding of toolpath strategies for hard stone.
  • Expertise in tool calibration, feed / speed optimization, and coolant management.
  • Knowledge of diamond tool selection and wear behavior.
  • Familiarity with robotic or gantry-based CNC systems.

    • Behavioral Competencies :

  • Detail-oriented and methodical with artistic sensitivity.
  • Strong spatial visualization and analytical thinking.
  • Ability to work cross-functionally with sculptors, designers, and engineers.
  • Dedication to quality, heritage, and innovation.

    • Deliverables :

  • Approved and verified toolpaths for each stone component.
  • Setup sheets and machining logs for traceability.
  • 3D and 2D data archives with full documentation trail.
  • Feedback reports for machining accuracy and optimization.
