- Work in conventional machines: turning (Lathe),milling and grinding .

- CNC Programmer AND CNC MACHINIST

• Perform CAD/CAM programming for CNC processes using Catia V5 and

Mastercam X6, for CNC 3 axis Machining Center and CNC Lathe.

• Adjust machine feed and speed, change cutting tools, or adjust machine controls when automatic

programming is faulty or if machines malfunction.

• Maintain machine tools in proper operational condition.

• Study sample parts, blueprints, drawings, or engineering information to determine methods or

sequences of operations needed to fabricate products.

• Operate equipment to verify operational efficiency, Check work pieces to ensure that they are

properly lubricated or cooled.

• Listen to machines during operation to detect sounds such as those made by dull cutting tools or

excessive vibration and adjust machines to compensate for problems.

• Transfer commands from servers to computer numerical control (CNC) modules, using computer

network links.

• Mount, install, align, and secure tools, attachments, fixtures, and work pieces on machines, using

hand tools and precision measuring instruments.

• Monitor machine operation and control panel displays and compare readings to specifications to

detect malfunctions.

• Modify cutting programs to account for problems encountered during operation and save modified

programs.

• Remove burrs, sharp edges, rust, or scale from work pieces, using files, hand grinders, wire brushes,

or power tools.

• Measure dimensions of finished work pieces to ensure conformance to specifications, using

precision.
