Numerical Control (NC) Lathe Operators are responsible for operating and maintaining precision lathes and other machine tools to produce high-quality parts. They must be able to interpret blueprints and drawings, program the NC lathe, and troubleshoot any problems that arise.

1. Operating the Lathe

NC Lathe Operators are responsible for setting up and operating the lathe, including selecting the appropriate tooling, determining the cutting speeds and feeds, and monitoring the operation of the machine.

• Set up and operate the NC lathe according to blueprints and drawings.
• Select the appropriate cutting tools, cutting speeds, and feeds for each job.
• Monitor the operation of the lathe and make any necessary adjustments.

2. Programming the Lathe

NC Lathe Operators must be able to program the lathe to perform the desired operations. This involves creating a program that specifies the path of the cutting tool, the cutting speeds and feeds, and other parameters.

• Create and edit NC programs using a computer-aided design (CAD) program.
• Download the NC program to the lathe controller.
• Troubleshoot any problems with the NC program.

3. Maintaining the Lathe

NC Lathe Operators are also responsible for maintaining the lathe and other equipment in good working order. This includes cleaning and lubricating the machine, changing the cutting tools, and making any necessary repairs.

• Clean and lubricate the lathe and other equipment.
• Change the cutting tools.
• Make any necessary repairs to the lathe and other equipment.

4. Quality Control

NC Lathe Operators are responsible for ensuring that the parts they produce meet the required quality standards. This involves inspecting the parts for accuracy, finish, and other specifications.

• Inspect the parts for accuracy, finish, and other specifications.
• Identify any defects and correct them.
• Document the inspection results.
