Introduction: What is machining?
The question “What is machining?” is central to understanding modern manufacturing technology. Machining is the processing of workpieces in which material is removed by cutting until the desired shape is achieved. This produces chips, which give the process its name.
Machining is a manufacturing process that plays a key role in the production of components for almost all industries, from the automotive and aerospace industries to art and woodworking.

Basics of machining
The purpose of machining is to transform a raw part into a precise workpiece. To do this, the excess material is removed in the form of chips. Depending on the process, this is done using different movements and tools.
Important features of machining:
- Removal of material by mechanical cutting
- Use of tools such as milling cutters, drills or turning tools
- Combination of cutting movement and feed movement
- Result: a defined, desired shape with high precision

Machining processes – an overview
Machining comprises a variety of processes that are systematically differentiated in machining technology.
The most important machining processes:
- Turning: Rotationally symmetrical components are produced by a stationary tool while the workpiece rotates. [More in the article: Turning vs. milling]
- Milling: A rotating milling cutter removes material to create surfaces, contours and shapes. [Read also: What is milling?]
- Drilling: Holes of different diameters are made with a drill.
- Grinding: For particularly smooth surfaces and tight tolerances.
These processes form the basis of industrial metalworking and are also of central importance for other materials such as wood or plastics.
CNC technologies in machining
Modern machining technology is no longer conceivable without CNC technologies. CNC machines control movements and processes and guarantee maximum precision and productivity.
- CNC milling: Processing of complex 3D geometries.
- CNC lathe: Efficient production of rotationally symmetrical parts.
- CNC boring mills: Precise production of bores.

The combination of automation and CNC machining leads to significant advantages: fewer errors, shorter machining times and consistent quality, even for large series.
The role of machining in production
Machining plays a central role in production technology. Without this process, it would not be possible to manufacture complex products in large quantities and with consistent quality.
- In the automotive industry, engine parts, gearbox housings or fixtures are manufactured by machining. Our products in fixture construction
- In the aerospace industry, machining enables the processing of high-strength materials such as titanium or aluminum.
- In art and woodworking, machining creates individual shapes and decorative contours.
This means that machining not only meets industrial requirements, but also creative demands in terms of design.
Significance of the chips
The characteristic feature of machining is the chips produced. They provide valuable information about the process:
- Chip shape: indicates whether the cutting speed and feed rate are optimal.
- Color: indicates temperature and heat dissipation.
- Size: depends on tool geometry and material.
Efficient chip formation is crucial for the quality of the workpiece and the service life of the tool. Modern CNC machine tools monitor these parameters automatically.
Automation and productivity
The integration of automation into machining has permanently changed the industry. In the past, many processes had to be monitored manually; today, CNC technologies take over these tasks.
This leads to:
- increased productivity through uninterrupted processes,
- greater efficiency thanks to shorter set-up times,
- improved quality through constant parameters.

What is machining in detail?
When people ask the question “What is machining?”, they often mean the difference to other manufacturing processes. In contrast to primary shaping or forming, machining is based on the targeted removal of material by cutting. A precise workpiece in the desired shape is produced step by step from a raw part.
Machining technology is one of the most important foundations of modern production technology. Processes such as turning, milling and drilling are just as much a part of it as high-precision grinding. More details on CNC processes in toolmaking
Machining plays an indispensable role in the automotive and aerospace industries in particular. Without the ability to manufacture precise components with tight tolerances, neither series production nor the manufacture of safety-relevant components would be possible.

CNC machines in machining
Machining is no longer conceivable without modern CNC machines. They enable high-precision machining techniques that deliver reliable results regardless of the complexity of the workpiece.
One example: Whereas with conventional lathes the operator had to control every movement himself, today CNC lathes take over all processes automatically. This not only increases efficiency, but also product quality.
Developments in the field of CNC milling are also impressive: complex 5-axis milling machines produce components in a single pass that previously required several machines.

CNC machining as the key to precision
CNC machining refers to the entire process of manufacturing components using CNC-controlled machines. This includes milling, turning, drilling and grinding, which run fully automatically in CNC machine tools.
Advantages of CNC machining:
- Precision: even complex geometries are implemented exactly.
- Productivity: high output thanks to automated processes.
- Flexibility: different materials such as metal, plastic or wood can be processed.
- Quality: consistent dimensional accuracy in series and for individual parts.

The importance of this method is enormous: without CNC machining, neither highly complex aircraft parts nor precise automotive components of the current quality would be possible.
Quality assurance in machining
Quality is a key factor in all machining processes. Even the smallest deviations in shaping can result in components not fulfilling their function.
Therefore, in modern manufacturing environments, measures such as:
- Process monitoring via sensors,
- Automated measuring cycles in CNC machine tools,
- and digital documentation of the production parameters.
This ensures that every workpiece achieves the same high quality – regardless of whether it is a single piece or a series.

Conclusion: The future of machining
Machining is much more than a traditional manufacturing process; it is the foundation of modern industrial production. Whether in the automotive industry, in aerospace or in specialized areas such as medical technology: without precise machining processes, many products that we take for granted today could not be manufactured.
In particular, the combination of traditional processes such as turning, milling, drilling and grinding with modern CNC technology has fundamentally changed the industry in recent decades. Whereas in the past each workpiece had to be monitored and controlled manually, today CNC machine tools and automated systems perform these tasks with an accuracy that could hardly be achieved manually. The result is a production process that combines maximum precision, consistent quality and maximum productivity.
At the same time, CNC machining is constantly evolving. In the future, AI-supported control systems and fully networked production environments will help to make processes not only more efficient, but also more intelligent. Predictive maintenance will minimize downtimes, while the integration of automation and robotics will transform entire production lines. This will shift the role of humans away from manual control and towards planning, monitoring and optimizing complex systems.
For companies like Bharat Forge Daun, this means that machining remains not only a tool for the present, but also a key to the future. By combining decades of experience in toolmaking, state-of-the-art CNC machining and customer-oriented solutions, it is possible to manufacture components and products that meet the highest standards of quality, safety and efficiency.
