- Department: Production / Machine Shop

- Reports To: Senior CNC Programmer / Machine Shop Incharge

- Employment Type: Full-time [1, 2, 3]

Key Responsibilities

- Program Assistance & Editing: Assist in developing 2D and 3D CNC programs for VTL machines. Edit and optimize existing G-code and M-code programs directly on controllers to adjust speed, feed, and depth of cuts. [1, 2, 3, 4, 5, 6]

- Blueprint Interpretation: Read and accurately interpret technical manufacturing drawings, engineering blueprints, and GD&T; symbols. [1, 2]

- Machine & Tool Setup: Assist operators in machine setup, including adjusting chuck jaws, workholding fixtures, setting tool offsets, and inputting wear geometries. [1, 2, 3]

- Software Operations: Utilize CAM software (such as Mastercam or Delcam/Powermill) under supervision to generate toolpaths for turning, facing, boring, and grooving operations. [1, 2, 3]

- Quality & Inspection: Perform in-process dimension checks using precision instruments (e.g., Vernier calipers, micrometers, bore gauges, pie tapes)



to guarantee parts match technical specifications. [1, 2, 3]

- Troubleshooting & Maintenance: Identify programming errors during dry runs or initial batch tests, perform minor program debugging, and carry out basic operator-level machine upkeep. [1, 2, 3]

Required Technical Skills & Competencies

- Controller Knowledge: Hands-on familiarity with operating and troubleshooting Fanuc or Siemens control systems.

- Programming Languages: Basic to intermediate proficiency in manual G-code and M-code editing.

- CAD/CAM Literacy: Exposure to design and manufacturing tools like Mastercam, AutoCAD, or similar structural software.

- Metrology: Mastery of precision measuring instruments to verify strict tolerances. [1, 2, 3, 4, 5, 6, 7]

Qualifications & Experience

- Education: ITI / Diploma in Mechanical Engineering, Production Engineering, Machinist, or Fitter trade.

- Experience: 1 to 3 years of working experience as a VTL machine operator, setter, or junior programmer within a heavy engineering or valve/aerospace manufacturing toolroom workplace. [1, 2, 3, 4, 5, 6]

If you would like to customize this further, let me know:

- What specific industry or product type (e.g., valves, aerospace parts, heavy automotive castings) your company manufactures.

- The exact CAD/CAM software or controller brands used on your shop floor.

- Any specific company benefits or shift requirements you need to include. [1, 2, 3, 4, 5, 6, 7]
