What does a machinist do?

Machinists are skilled professionals who create metal works by using different machines. They work with clients to bring their clients' vision to life. They study the blueprints of the product that needs to be done and identify the parts that will need fabrication through machining. They then prepare the materials and equipment. Machinists use different tools such as grinders, drills, lathes, polishers, and milling equipment to create parts that are made of metal. They may sometimes work with other materials such as wood or plastic, but this is seldom. Machinists are expected to be proficient in the use of the machines, to be precise with their work, and can work within the committed timeline.

What does a numerical control operator do?

A numerical control operator is responsible for monitoring machinery and managing computer-generated equipment to produce tools and components from various mechanical resources. Numerical control operators must have extensive knowledge with the technology and mechanical industry to perform basic troubleshooting and detect malfunctions during operations. A numerical control operator duties' also include inspecting equipment setup and finished products, ensuring high-quality parts, reviewing blueprints, following client's specifications for making adjustments, and adhering to the safety guidelines and procedures required by the business.
