CNC programming: a complete guide

Programming a computer numerical control machine, also known as a CNC machine, is not a simple operation, and requires a certain amount of experience in the field. When we talk about CNC programming, we’re referring to the process of creating computer commands, generally G-codes, used to control these automated production tools, able to carry out precise and complex operations, often for the metalworking sector, such as cutting, milling and drilling on a variety of materials. These instructions include: information on the movements of the tool, the speed of the spindle, feed rates, tool changes and other parameters necessary to carry out a particular process. Each process in the programming of the CNC machine tool is carried out using an integrated electronic device, usually an on-board computer.

A single, evolved partner

Since it was founded 25 years ago, Assistec has developed its service offering with increasingly innovative proposals. Today, the company also stands out by offering modular robot cells and an advanced service concept

Evolution is the basis of adaptation and survival of species. It applies in biology as well as in economic and industrial dynamics: markets change, technologies update, companies evolve.
Antonio La Placa's story is a striking example of this evolutionary capacity: after gaining extensive experience in Germany as a FANUC technician, in 1998 he returned to Italy where he founded Assistec. Initially focused on the electronic technical support of CNC machine tools for chip removal equipped with FANUC components (numerical controls, motors, drives, power supplies, electronic boards), he soon expanded his offer with additional, increasingly advanced services.

From 06 to 08 March at Bolognafiere, MECSPE 2024, the largest event dedicated to innovations for the manufacturing industry, returns.

Assistec will be present at the exhibition with a stand in Hall 30, Stand A54.

At the Assistec stand you will be able to discover the latest in automation and control systems for the manufacturing industry.

Exploring the different types of CNC machines

It's clear that the market for CNC machine tools is just as varied as the tasks these machines have to perform. This is because, with the advent of Industry 4.0 and modern smart factories, these machines have gradually taken on a more predominant role within industries, particularly manufacturing. CNC technology offers efficiency, precision and consistency, which are difficult to achieve with manual machining processes. There are various methods for classifying CNC machines, most of which are based on their design and intended tasks. Among the various types of CNC machines are milling machines, lathes, laser or plasma cutting machines, drilling machines, and grinding machines. They each have their own unique features and functionalities that can be customised using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs, enabling precise control over the movements of cutting tools and workpieces.

CNC machine tool maintenance: a guarantee of optimal performance

The maintenance and overhaul of CNC machine tools should not be confused with their repair. While repair is requested by the customer when a machine malfunctions, causing an emergency that could also lead to a halt in production, an overhaul is a scheduled or planned intervention conducted in agreement with a technological partner. During an overhaul, the machine is completely disassembled, and each individual component is carefully analysed and, if necessary, replaced or repaired. Regular overhauls are essential to ensure efficiency, precision and longevity of CNC machines. This preventive and proactive approach enables the resolution of minor issues before they cause serious damage.

AI at the service of machine tools

Artificial Intelligence is now among us. Just as electricity did a hundred years ago, AI today promises to change the world. No industrial sector is exempt from this epoch-making change, from the food industry to manufacturing, to mechanical engineering and many others. In addition to being on everyone's lips, the advent of Artificial Intelligence is increasingly imposing itself in the world of work, marking a new step forward for Industry 5.0, so much so as to raise legitimate concerns as opposed to great expectations from the point of view of technological optimisation in contemporary smart factories. In particular, with regard to integration with the CNC machine park, the coupling of automated systems such as robots and cobots, and the improvement of production flow and safety in the workplace.

The importance of preventive maintenance for CNC machine tools

Just like any other equipment within a company, it is crucial to check the health of machine tools. Failure to do so can result in very serious risks, including decreased productivity, machine downtime and even unexpected repair expenses. This is why, in recent years, many manufacturers have embraced a philosophy of prevention by conducting regular and rigorous checks on CNCs and replacing mechanical and electrical components subject to wear and tear. Otherwise, meeting the standards demanded of a modern smart factory operating within an Industry 4.0 supply chain would be impossible.

Regeneration of Electronic Spare Parts is the first step towards Sustainability

Nowadays, there is a lot of discussion about environmental and social sustainability, raising various questions about how we can achieve the goals laid out in the Agenda 2030, which was drawn up and signed by the United Nations. In a global context where it is necessary to bring about change, we at Assistec are increasingly recognising the importance of embracing an innovative mindset based on the concepts of Sustainability and Circular Economy.

Mechanical support on machine tools

Do you own a metalworking business? How often have malfunctions prevented your machine tool from starting or triggered emergency alarms? Every time it happens, not only is valuable time wasted, but there is also the risk of more severe consequences, such as a production halt or financial loss. Rely on Assistec for the mechanical servicing of your machine fleet, ensuring optimal functionality of your industrial equipment.

Più Increased safety for your machine tools

Numerical control machines play a central role in modern smart factories that have embraced the benefits and challenges of Industry 4.0. Affinché However, they must function optimally in order to consistently perform at their maximum capacity. Otherwise, there is a risk of unforeseen production slowdowns, machine downtime and, in some cases, even severe damages and financial losses. How can we prevent these risks? By scheduling an annual electronic and mechanical check-up. Performing scheduled preventive maintenance on your CNC machines means safeguarding the well-being of your personnel and the entire production chain.
