Our world is surrounded by complex technology that evolves at high speed. In everyday life, we see many complex parts such as gears and components within machinery, making one wonder what goes into their manufacturing.
Well, for most of these products and to the question of how they are manufactured, the answer is the same: precision machining.
Computer numerical control (CNC) processes have been the cornerstone of modern industries, producing parts in an automated manner at unimaginable production speeds. The precision machining CNC has taken it even further, adding precision and simplifying the manufacturing process.
The precision machining are a type of machining process that uses computer-controlled machines for the production of parts. It is a high-speed machining process for manufacturing parts that require close tolerances, high complexity, or both. The precision machining They can be performed by a qualified precision machinist operator or even by high-speed robotics.
It is a subtractive manufacturing process where the machine starts from a block and removes material with a cutting tool. The precision machining They are frequently used to make a variety of parts that fit and work together.
Precision machining: this is how efficiency is achieved
The precision machining successful are based on a combination of two factors:
First of all, the precision machining Quality cuts require a high-end cutting tool capable of carefully removing material to match the desired product dimensions.
Second, the process requires a computer numerical control (CNC) machine. Typically incorporating high-speed robotics, the CNC machine automatically controls the cutting tool, directing it where to cut/mill into the workpiece.
Most companies precision machining They work with a series of similar steps for various types of parts.
- Design the graphic model
A graphic model is required to create any part. This is achieved with the help of computer-aided design (CAD) software. CAD software allows the designer to create 2D and 3D models of any part for manufacturing.
- Convert CAD to CAM
Computer-aided design creates a graphic representation of the part in a digital format. This representation is easy to understand for designers, operators and manufacturers. However, the CNC machines used to create the part do not directly understand this digital format.
The machine understands the coordinates where it can move the cutting tool or move the workpiece. Therefore, CNC machines require that the part design be in a suitable format that provides the necessary manufacturing instructions.
- Machine configuration
Once the designs are ready in CAM format, it is time to do the machine setup. Typically this will require calibration of the machine tool and mounting the workpiece to the machine.
