CNC Machining in the Automotive Industry


The year 1886 in history is known as the birth year of the modern car. Because in that year, a German inventor Karl Benz patented his Benz Patent-Motorwagen. Cars became widely available in the early 20th century and the 1908 Model T (It is an American car manufactured by the Ford Motor Company) was amongst the first cars available to the general public.

The revolution occurred when cars were accessible to the masses and their commercial manufacturing started on a large scale. This drastically changed the living standards of the civilizations and it also created a new workforce and introduced a new aspect of popular culture.

At those times, cars were manufactured with human hands. There were no such technologies that are easily available during that age like Computer Numerical Control machining or Artificial Intelligence.

At present age, there is almost no segment of life where the automotive industry is not playing its role. As time went away, its role will be even bigger. In 2021, global sales of automobiles are forecast to about 70 million units. The most important segment of the automotive industry is commercial vehicles and passenger cars. China is counted among the largest automobile markets worldwide, both in terms of sales and production.

Since the manufacturing of the first car, the automotive manufacturing processes have evolved totally. The technological revolution has made mass production extremely easy. Since the 1960s, robots have become commonplace that carry out welding and assembly in a much shorter timeframe, and working with a human, that would never be possible.

When prototyping and mass-production of certain automotive parts are concerned, then CNC machining serves this purpose very well. CNC machining makes this possible using computer control instructions and automation. And performs many processes like drilling and boring with ease and at faster rates. It enables CNC technology a viable and versatile option for the automotive industry that offers increased production speed, high precision, repeatability, and cost-effectiveness.

Parts Manufacturing Using CNC Automotive

When the automotive industry selects any manufacturing technique, the thing that they look for is excellent performance, durability, and cost-saving. Several machining techniques are used in this industry for the production of various vehicle parts such as body sheets, windscreens, door panels, and various internal and external components. CNC machining offers these characteristics of high precision, excellent efficiency, and accuracy for the mass-production of automotive parts. Therefore, CNC machining is becoming more and more popular for automotive industry productions.

Well,there are many specific parts being prototyped and manufactured using CNC automotive, like the engine cylinder. A large block of aluminum is converted into an engine block or an engine’s cylinder and the piston moves up and down at very high speed and extreme temperatures. In this way, one form of energy is transformed into mechanical energy. 

Likewise, by applying the CNC process to acrylic glass or PMMA (Polymethylmethacrylate), the interior and exterior lightening of the vehicle can be manufactured. Other parts include exhaust parts, suspension parts, carburetor housings, etc. Since all the manufacturing process is controlled using numerical controlled instructions that ensure superb processing accuracy and reduce the chances of human errors. One more advantage of using CNC automotive is that it offers quick design customization of the part because we can easily alter the CAD design.

Advantages of CNC Automotive

CNC machining offers many advantages for the automotive industry and it has made production extremely fast. A few of the advantages are given below

Higher Production

Since all the CNC machining process is controlled using numerical instructions through a computer. Therefore, it is much faster than traditional machining. To manufacture a vehicle part, you only need to create a design of the product and then generate relevant CAM code. This code is a set of instructions that tell the different machines and tools, how to execute many processes effectively to manufacture a specific part design. By implementing the same method, you can manufacture as many designs as you want in less amount of time.

As all the process is automated and very fast. So, it saves a lot of time. A very good benefit of using CNC machining in the automotive industry is that it enables mass-production manufacturing within less time. Thus, ensures higher production.

High-Precision Parts

The automotive industry needs such a machining technology that can assure high-precision production of parts. Since a lot of money, time, and the company’s reputation is at stake. It is not even feasible to imagine, to ruin and scrap a whole batch of assembly-line production due to less precise products. Therefore, CNC automotive is a better choice to manufacture high-precision parts.

Since all the CNC machining process is automated and computerized control that fairly reduces the chances of errors. CNC machining offers tight tolerances (for metal and plastic parts that can sustain extreme pressures and temperatures), excellent mechanical efficiency, and superb processing accuracy. Thus, enables CNC automotive a high-precision machining technology.


In the automotive industry, mostly a large volume of a single component is required and, in this scenario, CNC machining serves this purpose wonderfully and effectively. To manufacture a large batch of the same part, it is only required to run the process as many times as you want. Nothing special needs to be done. You already have CAD design, CAM code, tool, and machine set up ready. Run the whole process again and again to get your required number of the same parts.


One of the main advantages of the automotive CNC is that it offers prototyping and mass-production at a very reasonable price. If a company demands to manufacture a prototype to test their new design, then it can be done very easily at low prices. On the other hand, if they want to make changes in their design then customizing apart even during the process in CNC, is quite easy. You need to amend the CAD design only. Other than this, this technology reduces the cost of labor and chances of errors that cost schedule delays and material to scrap.

Introduction of Artificial Intelligence in CNC Machining

Artificial Intelligence is the implementation of the system of algorithms. These algorithms are optimized automatically as they undergo some processes to train them to that level where they can make their own decisions. Since AI has been implemented in many manufacturing processes that made them wonderfully effective and efficient. It has reduced the human interaction to a minimum and the decisions are taken by the algorithm itself. In the future, when AI will be more developed then, it will completely revolutionize CNC machining.

Why is there a need for other codes of instructions that are already possessed by computer numerical control? Well, the answer to this question is that numerical instructions are not that intelligent as the algorithms in Artificial Intelligence.

For example, implementing Artificial Intelligence can fairly reduce the downtime of the machine. When the machine starts running, it will possess some faults that will be difficult to detect. So, it will lead to machine rundown and reduced productivity. But by introducing AI in the CNC machining process, the machine will be able to self-diagnose those faults using AI algorithms and will be greatly helpful in saving many hours of machine downtime.

Furthermore, the introduction of Artificial Intelligence in CNC automotive will assist in quality control of the mass-production by maintaining the consistency of the output. The output will be frequently monitored and checked by AI algorithms to ensure high-precision manufacturing. It will make the process more cost-effective and increase efficiency and accuracy.

Application of AI-Assisted CNC in Self-Driving Cars

A self-driving car (also known as an autonomous vehicle, driverless car, or robo-car) is a vehicle that can sense its surrounding environment and can travel safely with little or no human input. The car judges its surroundings by sensibly utilizing various sensors. All the information about the right path and hurdles is intelligently monitored and checked by the algorithms and then a wise decision is made accordingly.

Due to the increased efficiency and processing accuracy, the AI has achieved a valuable eminence in CNC automotive. The AI-assisted CNC automotive is used in the manufacturing of different automotive parts as well as automotive machining. The reason being, an autonomous car requires more accuracy than human-driven cars. The chances of errors in self-driven cars can be very devastating. So, with the introduction of AI in the CNC automotive the chances of errors can be reduced fairly. Moreover, AI-assisted CNC automotive is also used in the manufacturing of electrical and mechanical components of self-driving cars.


The role of CNC machining in the automotive industry is of great importance. Since automotive parts require high-precision and very good accuracy, this can be greatly fulfilled by CNC machining. Along with this, CNC automotive offers superb efficiency, repeatability, errorless mass-production, and cost-effective products.

The role of Artificial Intelligence in CNC automotive and self-driven cars is becoming eminent day by day and it will increase more with the advancement in AI.
