Computer numerical control (CNC) has influenced the growth of various products we have today. It is a method for automating control of machine tools using software embedded in a microcomputer attached to the tool. Mills, lathes, routers, grinders, and lasers are common machine tools whose operations can be automated with CNC. It can also be used to control non-machine tools, such as welding, electronic assembly, and filament-winding machines.
CNC machines are gaining huge popularity due to their high accuracy, time and focus on energy efficiency. According to Fortune Business Insights, the global CNC machine market is projected to grow from US$86.83 billion in 2022 to US$140.78 billion by 2029, at a CAGR of 7.1%, according to Fortune Business Insights.
In recent years, there have been several developments that have further enhanced the precision and accuracy of CNC. One of these developments is the use of advanced software and algorithms that can optimize the machining process to minimize errors and improve efficiency. These software programs can analyse the machining process in real-time, and adjust as needed to ensure that the finished product meets the desired specifications. For example, some software programs can automatically adjust the feed rate and cutting speed to achieve the best possible finish, or they can adjust the cutting tool path to minimize tool wear and extend the life of the tool.
CNC software advancements
As modern industries demand for more complex and precise machine tools for high-quality standards and protocols, thus is the need for advanced CNC software. The most common CNC software is the CAD/CAM integration. CAD, or computer-aided design, helps in creating 2D and 3D seamless design processes. Most designers use this software because of its speed and accuracy. On the other hand, CAM, or computer-aided manufacturing, improves precision during manufacturing processes such as cutting, drilling, or milling by following the instructions on the codes. The CAM software package has greatly advanced over the years to become more efficient, accurate, and innovative workflows in metalworking tools. Another noteworthy software is CNC simulation. This is an extremely valuable resource because it has the power to plan and verify CNC machining. It includes all the components found in the CAD CAM software environment. Therefore, you can predict the future of your machining and optimise time, processes, and resources.
Below are some companies who offer advanced CNC software to date:
Fusion 360 from Autodesk is among the most renowned free CNC software for professional product and design manufacturing. It has both 3D CAD/CAM functionalities. Its computer-aided manufacturing software is ideal for milling and laser techniques. It can connect your design to manufacturing techniques such as turning, turn-milling, probing and part inspection, 2.5-axis milling, 3-axis milling, and 4- and 5-axis simultaneous milling.
EnRoute is an easy-to-use CNC software for textured paneling, cutting, creative designing, and metal and aluminum machining, among other manufacturing processes. Its designs are ideal for use on knife-cutters, waterjets, plasma cutters, CNC router software, and lasers. EnRoute has realistic simulations that you can use to spot errors that might interfere with your design manufacturing. You can also use it to test different models for your manufacturing processes. In addition, this software features precision editing tools that you can apply to enhance your shapes when drawing freehand.
Hexagon’s CNC simulation software solutions address the challenges using a machine digital twin to test and prove out G-code for CNC machines in a virtual environment. They allow manufacturers to validate CAD CAM programs prior to production to avoid costly collisions and mitigate against anomalies in machine tool behaviour. Proving programs via simulation also reserves machine time for manufacturing operations, minimising downtime for essential equipment.
Conclusion
Using the right CNC software can help industrial manufacturers understand various profitable trends in order to develop a good business strategy. With the mass production of complex applications, such as automotive, medical, aerospace and semiconductor industries, demand for CNC machine tools is indeed expected to increase. Knowing the exact software tool to use allows manufacturers to control their equipment and give them an edge over their competitors.
