VMC Operator & Programmer

Position: VMC Operator Cum Programmer
Core Responsibilities  I. Programming and Simulation    Develop CNC Programs:  Write and edit G-code and M-code to direct the machine's movements.
CAD/CAM Integration:  Use software like  Mastercam, Delcam (Power Mill), or Siemens NX  to convert 2D/3D drawings into toolpaths.
Optimization:  Fine-tune feed rates, spindle speeds, and cutting depths to reduce cycle time while maintaining tool life.
Trial Runs:  Perform virtual simulations to check for potential collisions or errors before the actual cut.
II. Machine Setup and Operation    Job Setting:  Select and install the correct work-holding devices (vices, fixtures, or magnetic tables).
Tooling:  Load the required cutting tools into the Automatic Tool Changer (ATC) and set tool offsets.
Component Loading:  Secure raw materials (billets, castings, or plates) accurately on the machine bed.
Execution:  Monitor the machining process to ensure there are no abnormalities like excessive vibration or tool breakage.
III. Quality Control and Maintenance    Inspection:  Use precision instruments such as  micrometers, vernier calipers, and height gauges  to verify the dimensions of the 'first-off' part.
Blueprint Reading:  Interpret complex engineering drawings, including  GD&T  (Geometric Dimensioning and Tolerancing) symbols.
Preventive Maintenance:  Perform daily checks on coolant levels, lubrication, and chip disposal to ensure machine health.
