“Individuals pursuing a career in my field have the flexibility to explore opportunities across various types of organizations, ranging from large technology conglomerates to burgeoning startups,” Chris Lee notes. “With CAM programming skills being widely applicable, professionals can find rewarding roles in an array of industries that rely on manufacturing processes. These sectors may include, but are not limited to, aerospace, defense, commercial manufacturing, and prototype development.”

CAM Programmers are relied upon to write the instructions for CNC machines to produce products that conform to very precise specifications. Their work must be meticulous and error-free, as they consider multiple factors such as the right materials, tools, and equipment to use. 

Manufacturing worksites can be loud, with numerous hazards to be wary of. Programmers who work directly with or around CNC machines must be conscious of all risks and wear appropriate personal protective gear, including goggles, hearing protection, and gloves, as needed. 

Chris Lee provides an inside look: “A typical day for me begins with an in-depth review of the assigned project blueprint, focusing on identifying potential challenges or areas requiring specialized tooling and consideration. With a mental framework of my approach, I initiate a collaborative meeting with CAM programmers, CMM inspectors, and machine operators. We engage in a comprehensive discussion of the proposed strategies, addressing any additional concerns or potential obstacles. 

“Upon finalizing the most effective approach, I oversee the machine operation to produce the first article and submit it for inspection. Once the initial part is approved, I provide comprehensive work instructions to the operators to commence production. Concurrently, I manage any process errors that arise within our proprietary software or systems, diligently documenting and seeking solutions for the continual improvement of our processes. This ensures a seamless and efficient workflow, fostering an environment of excellence and innovation in our operations.”

An interesting trend that affects computer-aided manufacturing is 3D printing. Shops can now print parts that CNC machines can polish up and finish, which may impact the demand for CAM programming in the future. Meanwhile, there’s an increased demand for CAD and CAM capabilities to be integrated into single platforms (instead of relying on two different programs). Another trend is the use of CAM software digital twins that simulate everything a CNC machine will do. This allows the programmer to troubleshoot ahead of time and make adjustments before pushing the instructions to the actual CNC machine.

Some trends depend on the sector in which the CAM Programmer works. For example, Chris Lee outlines current trends in the aerospace industry. “As we witness the unfolding of a new space race, propelled by companies like SpaceX and their efforts to reduce orbital launch costs, the demand for skilled professionals in 5-axis programming has soared. Due to the intricate nature of the components involved in these cutting-edge projects, versatility and expertise across various machining processes are highly desirable.”

Chris also notes that programmers “with experience in 3-axis, 4-axis, and 5-axis machining, as well as turning, and mill-turn operations, possess a significant competitive advantage in the field.”

People who get into CAM Programming usually enjoy working with software as well as with their hands. They are safety-conscious and feel comfortable working around loud relatively dangerous machines. They might have enjoyed math and computer programming courses in high school or liked doing projects in shop classes. 

“Individuals in my occupation often exhibit a passion for creating and building from a young age,” Chris Lee explains. “This enthusiasm may manifest through various mediums, such as paper crafts, plastics, or metalwork. Engaging in a wide range of interests and hobbies contributes to shaping a multifaceted mindset. Exposure to diverse experiences allows individuals to develop versatile problem-solving skills and innovative approaches, which are crucial in a dynamic field such as ours. Embracing these myriad interests and pursuits not only enriches one's personal life but also cultivates essential abilities that translate seamlessly into a successful career in this industry.”
