Automation is the future of CNC

CNC (computer numerical control) automation refers to integrating automated systems and technologies into CNC machines to perform specific tasks in the manufacturing process. Automating repetitive or time-consuming tasks, such as loading and unloading parts or changing machine tool parts, helps enhance efficiency, productivity, speed, and precision with minimal operator oversight required. CNC automation also enables 24/7 machines — including mills, lathes and drills — to operate continually for optimal uptime and production.

There are three main types of automation used in manufacturing. Fixed automation uses specialized equipment for high-volume, repetitive tasks during long production runs of identical products. Programmable automation is primarily used during batch production, where runs are repeated, but the setup changes for different types of products. Flexible automation can quickly and easily switch to different products and production volumes without significant reconfiguration or unplanned downtime.

Automation can increase productivity and operational efficiency, helping manufacturers stay competitive in modern manufacturing environments. Okuma Flexible Machining Center (FMC) solutions include robots, cobots, automatic pallet changers, bar feeders and gantry loaders.

Lights out manufacturing (LOM) refers to a highly automated manufacturing production environment where operations run autonomously and continuously (often 24/7) with minimal or no machine operators present. The goal of LOM is to achieve maximum productivity and reduce downtime.

In CNC machining, automation offers several key benefits increased productivity (tasks can be performed autonomously and continuously), improved precision (minimized human variability), reduced labor costs (fewer machine operators are needed), lower lead times (shorter setup times maximizing production cycles), and enhanced safety (reduces operators’ exposure to repetitive motions and potentially hazardous tasks).

Automation is not intended to replace machine operators, but integrating automation into manufacturing may shift some personnel roles and responsibilities. For example, automation may perform repetitive and time-consuming tasks, like loading and unloading materials. However, technicians are still critical in overseeing the automation process, troubleshooting potential issues, and performing regular maintenance for enhanced quality control and operational efficiency.

All industries can benefit from CNC automation, particularly those that require high-precision and high-volume production, such as aerospace, automotive, valves, electrical manufacturing equipment, and metalworking.

CNC automation is the future in manufacturing, with the industry quickly moving toward greater integration of automation solutions. This shift will drive the evolution of manufacturing into digital- and AI-driven, self-optimizing environments where machines operate more efficiently. As automation becomes more scalable and adaptable, manufacturers will increasingly be prepared to respond faster to market demands and enhance productivity.
