What Is A CNC Machinist?
Computer Numerical Control (CNC) machinists design, set up and operate different kinds of CNC equipment and machines. They are exceptionally skilled professionals who combine elements of research, mechanical design, technical drawing, mathematics and programming skills in a professional space to create tools and products. A skilled CNC machinist may track and monitor each product through every phase of its design and creation.
CNC machinists are highly sought-after professionals, because the production of tools and other parts increasingly relies on computer programs nowadays. They are responsible for the setup and operation of CNC machinery, which is heavy machinery that is designed for the production of both plastic and metal components. They may also inspect the final product, ensure that it is free from defects and approve that the products are ready for the market or the next production stage. Automotive, aerospace and power and manufacturing are a few industries where CNC machinists perform instrumental work.

How To Become A CNC Machinist
The job of a CNC machinist is highly technical and requires intensive training and preparation to master. To become a CNC machinist, you may either take an academic route or pursue vocational training. Here are some steps you can follow to learn how to become a CNC machinist:
1. Research the duties of a CNC machinist
There are different machinist jobs. If you are looking to pursue a career as a CNC machinist, knowing the specific career path you want to take is important. You may also want to ensure that you have or are interested in learning the required skills for the job. Knowing what type of job is most interesting to you can enable you to make the right decision on what combination of courses to pursue. Typically, there are three types of CNC machinists:
Operating machinists: The primary duty of an operating machinist is to ensure the optimal functioning of machines.
Set-up machinists: Set-up machinists are responsible for monitoring the equipment, making adjustments and performing other tasks to ensure flawless manufacturing operations.
Programming machinists: Programming machinists specialise in coding for CNC systems and updating existing programmes to produce parts that meet a set of prescribed specifications.

2. Take preparatory courses
A high school diploma is usually the minimum requirement to seek employment as a CNC machinist. You may consider pursuing a post-secondary CNC machinist programme after high school. This programme includes lessons in structured classrooms and practical training modules. Blueprint reading, technical drafting, machine tooling and metalworking are a few areas you can pursue courses in to prepare yourself for a CNC machinist training programme. You can also brush up on your algebra and trigonometry knowledge to enhance your visibility among other applicants.
3. Pursue a formal degree
While a professional degree is not a must-have qualification to work as a CNC machinist, most employers prefer to hire someone with a degree. If you opt for a certificate, it only takes a few months to learn basic skills such as measurement, inspection and blueprint reading. Technical colleges offer full CNC machinist degree programmes and they typically take two academic years to complete. These programmes provide educational classes and industry-specific courses to prepare students for the job market. Educational programmes cover subjects such as engineering, maths and computer technology. You may also learn about CAD/CAM and design technology.

4. Complete a formal apprenticeship
Becoming an excellent machinist takes time and intensive on-the-job training. Formal apprenticeships allow you to gain hands-on training and experience. An apprenticeship is an entry-level program that lasts up to four years, depending on your previous training and interest. In an apprenticeship, you may apply theoretical knowledge from classroom sessions to a practical environment to guide the hands-on experience of operating actual machines. Some of the skills and lessons learned in an apprenticeship program are:
Basics of CNC machine operation
Computer-Aided Design (CAD)
It is important to note that most employers seeking to hire CNC machinists may look at whether a candidate has previous experience in the field. Hence, completing an apprenticeship programme might be advantageous during a job search. Your school may be able to help link you with potential employers, such as local manufacturers, for apprenticeship opportunities.

5. Obtain relevant certifications
Regardless of whether or not you hold a degree, successfully completing an apprenticeship programme makes you qualified for certification as a credentialed worker in this field. Getting a certification is an indication that you have the right skill set to operate CNC machines. There are many institutes that offer certification programmes for CNC machinists, where candidates can appear for a performance-based written and practical exam. These institutes offer certifications at three levels:
Certified CNC Set-up Programmer
Certified Journey Worker
While certification is not a mandatory requirement, obtaining an endorsement from a credible institute has several advantages. From increasing your employability to offering better networking opportunities and enhancing your professional image, a certification is a worthwhile addition to your resume. It plays an important role in advancing your career and shows potential employers that you are regularly updating your skills.
