What Is A Machinist Job?

A machinist job is a set of duties that a machinist performs as part of their role, including:

Reviewing computer-aided designs, blueprints and technical drawings to understand the specifications and dimensions of the parts they produce
Operating heavy machineries, such as lathes, milling machines and grinders, to shape or modify metal parts and components to their exact specifications
Installing, aligning and securing cutting tools, fixtures and workpieces on the machine to prepare for the machining process
Monitoring the machine to ensure the product is of high quality and meets the specified requirements
Identifying machine damage, lubrication or vibration problems and performing routine maintenance tasks to keep them in good condition
Designing, setting up and operating Computer Numerical Control (CNC) machining for automating the control, movement and precision of machine tools through the use of embedded software
Using measuring equipment and visual inspection techniques to ensure the final metal parts or components meet the required specifications and quality standards

Machinist Job Requirements

Here are the requirements for the role of a machinist:

Education

Though there is no specific degree requirement, employers usually prefer candidates with diplomas or certifications from vocational training programmes. The Directorate General of Training under the Ministry of Skill Development and Entrepreneurship offers various programmes to help candidates learn trade skills and develop the necessary in-depth knowledge for the role. While the first year of the course covers basic fitting operations, such as making, filing or sawing, the second year covers advanced milling operations, including boring and gear cutting.

After completing the course, you require extensive practical training and experience to work in various industries, such as manufacturing, engineering, oil and gas and tool and die-making.

Career path

There are several career paths for candidates wanting to pursue a career in machinery. Some of them include:

Joining as a technician after completing the vocational training programme and advancing to senior roles, including supervisor and manager
Appearing for the 10+2 examination through the National Institute of Open Schooling to continue further education
Continuing your education by applying for a diploma in mechanical engineering, computer science engineering or a related field in any of the recognised institutes through lateral entry
Obtaining a National Apprenticeship Certificate by clearing the All India Trade Test for Apprentices after having worked for a minimum of three years in the trade
Joining advanced vocational training programmes to improve skills and knowledge in the areas of CNC machining, precision machining or advanced machining techniques

Certifications

Certifications can help you improve your skills and knowledge in areas including general machining skills, CNC programming and operation, quality control and safety. It can also help you advance to senior positions with better compensation and benefits. Here are some relevant certifications for the role:

Certificate Program in Precision Machinist
Certificate Program in CNC Technology
Certificate Program in Tool and Die Making

Skills

Here are some key core skills for the position:

Knowledge of technical designs and documentation

As a machinist, your primary role is to review the technical diagrams and engineering drawings for dimensions, annotations and tolerances. This provides detailed information on creating or shaping metal parts and components. This requires you to learn reading symbols and abbreviations, dimensions and section views and develop the ability to visualise the geometry of the finished part.

Ability to operate heavy machinery

Heavy machinery involves extensive use of hand and power tools, heavy lifting and pushing and pulling. The job may also require you to stand for long periods each day. This requires you to be physically fit and have good stamina. Improve your physical strength through regular exercise, strength-building workouts and a healthy diet.

Knowledge of safety standards

Adherence to manufacturers' guidelines and safety standards when operating heavy machinery or handling tools and equipment can prevent injuries in the workplace. Ensure that you understand how each machine works and the common machinery hazards. Additionally, make sure that you undergo periodic workplace safety training and review instruction manuals that detail machine safety guidelines.

Knowledge of CNC machining

CNC machining is a partially or fully automated process that enables machinists to direct the computer control systems to control the movement of machinery and perform the required actions. Knowledge of computer systems, including their controls, interfaces and functionalities, allows you to operate them effectively. Knowing programming languages such as G-code and M-code can also help you write, modify and troubleshoot CNC programs to achieve the desired machining outcomes.

Communication and collaboration

As a machinist, you interact with mechanical engineers, process teams, maintenance staff and other personnel. You also coordinate with quality control teams, floor supervisors and suppliers to ensure the high quality of the finished product and place orders for cutting tools, work holding fixtures and other necessary supplies for your work. Strong communication and collaboration skills can help you succeed in this role.

Work environment

Machinists usually work in industrial settings, often operating heavy machinery for long periods. There can be exposure to lubricants and coolants, resulting in skin irritation or respiratory issues. There can also be regular exposure to loud sounds due to heavy machines operating for long periods. Wear earplugs and protective equipment, such as gloves and safety glasses, and adhere to workplace safety measures and company guidelines.
