Automated CNC machining has helped make fabrication methods like just-in-time manufacturing and lights-out production feasible in high-volume production. When fully automated, CNC machines can achieve far greater efficiency and productivity than processes in which human workers are needed. Automated CNC machines have become standard in many machine shops, enabling them to replace personnel in activities that are especially hazardous and repetitive while increasing quality and precise tolerance.
Implementing automated CNC machines in production guides assembly, inspection, loading, unloading, and other operations using software rather than human management. This, in turn, allows a single employee to supervise several machines simultaneously. For some machine shops, this can even be done remotely. Automation also reduces costs, heightens safety, and reduces lead times, allowing manufacturers to boost production and become more competitive. The increased automation and repetition allow for high levels of consistent quality.
How Do Automated CNC Machines Aid Mass Production?
CNC technology allows machine shops to make precision parts far more quickly and in greater volume, while also improving quality and consistency in the items produced. Manufacturers can more easily scale their production by producing components at higher volumes. Decreasing fabrication times also allows manufacturers to produce more items in less time than conventional methods.
This is a crucial goal of mass production, which has brought the modern world a remarkably high standard of living. High-volume manufacturing lowers manufacturing costs by making manufacturing faster and more efficient and reduces the price per unit. When automated, CNC machines perform operations once done manually better and with minimal supervision than those once done by humans.
5 Ways in Which CNC Machining Augments High-Volume Production
The high degree of accuracy required for precision parts has made automated CNC machines a preferred fabrication method. CNC technology can be found in modern mills, lathes, turning centers, mill-turn centers, electric discharge machines (EDMs), laser cutters, waterjet cutters, and other equipment preprogrammed to produce various components. Using highly automated systems, CNC machines convert the language used to create computer-aided design (CAD) models into instructions for the tooling.
Using preprogrammed paths for cutting components, automated CNC machines incrementally remove bits from a piece of solid material until it reaches its final form. Though standard tolerances of +/- .005 inch (0.127 mm) are commonly applied, CNC machining can achieve even greater accuracy. Tolerances down to the micron range – less than one ten-thousandth of an inch – have become possible with specific, more sophisticated CNC machines.
To achieve this, machine shops must use the highest quality tooling to achieve the precision necessary. The greater the accuracy required for a part, the more complex the tooling and programming needed. Automated CNC machines are also often used to finish off components made via additive manufacturing, as 3D printing tends to produce less smooth finishes. Additionally, CNC machining is used to create molds for injection and other types of industrial molding when mass-producing precision parts.
Optimizes Efficiency
Optimization of fabrication processes to make them more efficient often involves automated equipment. CNC machines that utilize automation tend to use much less energy and reduce the amount of scrap produced. Through this greater efficiency and decreased waste, machine shops can reduce their impact on the environment, while also reducing their operational expenses.
Automated CNC machines provide the means for:
- Greater amounts of uptime
- Just-in-time manufacturing
- Lights-out production methods
- Performing secondary operations like deburring, gauging, and washing
- Quick and easy changeovers of tooling and other components
- Real-time communications with other equipment
Advanced CNC machines are made to fit into places where space is limited. Essentially robots, these automated CNC machines also offer an efficient means to utilize workspace.
Consistent Results
Closely connected to efficiency is the consistency of what automated CNC machines produce. Parts manufacturers must ensure that the components they manufacture don’t vary much, which is easier with an automated production system. CNC machines support consistency in fabrication far better than human machinists working on manual machines. The software integrated into a computerized CNC machine allows for reliable prediction of every tool’s movement, ensuring the exact toolpaths are followed. Automation results in a more consistent product, and once a toolpath is programmed, it allows higher volumes of components to be made consistently and in less time.
More Cost-Effective
The speed and precision of automated CNC machines are the underlying factors affecting the quality and expense of machined parts. This is especially true for more complex components. The production speed allows more parts to be made in a shorter time frame, while accurately applied tooling reduces waste. When combined, these make the use of CNC technology particularly cost-effective.
Most automated CNC machines can perform the work of between three and five people performing conventional machining tasks. When fully automated, CNC machine centers working on multiple axes and with advanced monitoring capabilities can replace up to ten machinists, especially when robotic systems for loading and unloading are included. This saves not just on labor costs but also lowers energy use per unit produced.
Fully automated CNC machines can work continuously and unintended around the clock. When able to operate constantly, machine shops can produce more components that are more cost-effective. With automated processes supported by manufacturing software, tooling changeovers can be performed seamlessly to diminish cycle times and produce parts at a lower cost per unit. This, in turn, allows machine shops to have shorter lead times, making manufacturers more competitive.
Lower Labor Requirements
With automated CNC machines, manufacturing processes require fewer workers. Even with a small labor force, it’s still possible to simultaneously have numerous projects on the go, as accuracy and speed increase when production is automated. CNC machines also require much less attention so employees can focus on other tasks for which humans are better equipped, like designing components for new customers. Automation doesn’t just mean saving on labor, however. It also allows a shop to increase output, boosting profitability.
Better Quality Control
Regardless of the type of manufacturing, quality control is far easier when automated. CNC machines enhance quality by removing almost every means of human error from the process. They allow machine shops to make components with extraordinarily tight tolerances to meet industry or regulatory standards. Advanced quality control methods are sometimes even integrated into automated CNC machine systems to give manufacturers greater confidence that the machined goods they produce are of the highest quality.
Automated CNC machines can support quality control by performing:
- Data analytics: Automated CNC machines with integrated analytics software can gather vast amounts of production data that help manufacturers make informed decisions on improving the components in their products.
- Monitoring tool condition: Using devices that measure wear and combined with monitoring systems that are automated, CNC machines can constantly scrutinize the condition of tooling and predict when it requires replacement.
- On-machine inspection: Probing systems for machine tools integrated into automated CNC machines allow inspections during production, enabling real-time corrections.
- Real-time monitoring: Collection of data regarding amount of cutting force applied, spindle speed, and wear of tooling allows operators to more quickly identify issues and make real-time adjustments to a machine’s configurations.
Automation can even prioritize production to enable quicker turnarounds and to better fulfill orders.
