15 computer numerical controller machinist skills for your resume and career

1. Calipers

Here's how computer numerical controller machinists use calipers:
  • Verify dimensions of parts machined using micrometers, calipers and other precision measuring instruments.
  • Completed daily measurements using hand micrometers and calipers on production parts.

2. Micrometers

A micrometer is a measuring instrument used in various laboratories to measure even the tiniest components in-depth with great precision and accuracy and to make precise linear measurements of dimensions such as diameters, thicknesses, and lengths of solid bodies. They are essential measuring instruments used by mechanical engineers, machinists, and workers in other technical professions. They allow workers to take extremely precise measurements, which can be viewed either in imperial or metric format. Most micrometers are designed to measure within one-thousandth of an inch! It's a snug fit. Accurate measurements like this are needed when even the smallest distance between objects can cause problems or difficulties.

Here's how computer numerical controller machinists use micrometers:
  • Verified conformance of finished work pieces to specifications using measuring instruments including microscopes, gauges, calipers and micrometers.
  • Measure and examine completed parts to ensure conformance to specifications using precision instruments, such as micrometers.

3. Manual Lathes

Here's how computer numerical controller machinists use manual lathes:
  • Experience working with manual lathes, mills, grinders (electrical and manual), drill press and radial arm drill.
  • Job duties include machining all components of hydraulic cylinders using Knuth CNC lathes, manual lathes, mills, and grinders.

4. Math

Here's how computer numerical controller machinists use math:
  • Calculated numerous mathematical calculations throughout each day, mostly using shop math and trigonometry for more difficult calculations.
  • Fulfilled calculating requirements, including basic math, geometry, and trigonometry.

5. G Code

Here's how computer numerical controller machinists use g code:
  • Make any revisions needed to enhance performance of CNC automated machinery, including edits for all G Codes and M Codes.
  • Write, program, set up and run Tree/Brother vertical mill using conversational G Codes as well as standard G Codes.

6. Grinders

Here's how computer numerical controller machinists use grinders:
  • Operated grinders efficiently for sharpening cutting tools.
  • Set up and ran CNC: Milling machines and creep feed grinders to manufacture blades and vanes for the aerospace industry.

7. Hand Tools

Here's how computer numerical controller machinists use hand tools:
  • Lifted blades on work holding devices using hoists; and positioned and secured them in machines using fasteners and hand tools.
  • Lifted metal stock and work-pieces manually or with hoists, positioned and secured them in machines using fasteners and hand tools.

8. Machine Shop

Here's how computer numerical controller machinists use machine shop:
  • Perform typical machine shop operations including setup and programming of machines.
  • Performed temporary piece work and consultation in different machine shops

9. GD

GD refers to Grade Delay and is often mentioned on report cards or academic records when the instructor of a particular subject decides to hold the grade of a student. This is usually done if the instructor wants the student to improve their grade by retaking the exam or doing something for extra credit that will ultimately enhance their overall grade. Eventually, when the grade is assigned, the GD is then replaced with the original grade.

Here's how computer numerical controller machinists use gd:
  • Work with Gd and t tolerances in a ISO certified shop.
  • Dialed in close tolerances sometimes using GD &T true positioning.

10. Aerospace

Aerospace refers to the physical science focusing on designing and developing, testing, and producing systems that aid in navigation to space or traverse through the earth's atmospheric zone.

Here's how computer numerical controller machinists use aerospace:
  • Obtained experience working on parts for medical instrumentation and implantation, as well as fuel systems/automotive components and aerospace defense products.
  • Operate vertical and horizontal milling machines to manufacture a multitude of detailed parts, including aerospace production.

11. Machine Tools

Here's how computer numerical controller machinists use machine tools:
  • Maintained machine tools in proper operational condition, and ensured machine efficiency.
  • Programmed and set up Computer Numerically Controlled machine tools.

12. Mazak

Here's how computer numerical controller machinists use mazak:
  • Work with HAAS and MAZAK CNC Machines, as well as mills and lathes.
  • Experienced in the use of MAZAK and FANUC machines 18t and 21t.

13. Safety Standards

Here's how computer numerical controller machinists use safety standards:
  • Collaborate with administrative and financial teams to establish viable support of safety standards.
  • Produced parts by setting up, programming and operating CNC machine; maintaining high quality product and safety standards.

14. G-Code

Here's how computer numerical controller machinists use g-code:
  • Edited G-code programs for optimum production efficiency.
  • Well-versed in conversational and G-Code controls

15. Troubleshoot

Troubleshooting is the process of analyzing and fixing any kind of problem in a system or a machine. Troubleshooting is the detailed yet quick search in the system for the main source of an issue and solving it.

Here's how computer numerical controller machinists use troubleshoot:
  • Resolved and troubleshoot any mechanical problems.
  • Diagnose and troubleshoot machine abnormalities.
