If the question “What is precise machining?” still remains in your mind, here’s the reply. Just as the name suggests, CNC precision machining comprises shaping raw material into a finished product by cutting out dissipations as designated by a Computer-Aided Design (CAD) or Computer-Aided Manufacturing (CAM) drawing. What’s more, operators use this process in different engineering processes and on diverse materials.
Before making any part by precision CNC process, using computer programs to make the product’s drawing is necessary. Specifically, these programs make extremely detailed 3D outlines that a precise machining process is necessary to follow to copy the product effectively. From toys to medical apparatus, complex automobile parts, or space shuttles, any product that has parts needs precision machining. Using computer-controlled equipment, the process uses actions like cutting, milling, turning, and electrical discharge machining to accomplish the ultimate product.
Although CNC precision machining requires the supervision of a skilled machinist, a machine does most of the labor mechanically. The computer software creates the design, another computer software then decodes it into manufacturing commands for the machine. A final post-processor software codes the instruction into information the machine can comprehend. The technicians then load the instruction into the CNC equipment to start the engineering process.
Tolerance is the amount of aberration in the measurement of a part that is suitable by predictable standards. A synonym for it is dimensional exactness. There is no typical tolerance for all precision CNC machining procedures. The severity of tolerance depends on the engineering process. The number of decimal places a tolerance value shows the severity of the extent.
Along with the swelling demand for CNC sheet metal cutting, new cutting knowledge is being established; which is more detailed and more cost-effective. When it comes to metal processing methods used nowadays; the most usual ones are laser cutting, plasma cutting, or water jet cutting. The choice of the cutting method greatly affects the overall cost of metal places making, i.e., structures, and their quality.

Laser metal cutting has been in use for more than 2 decades, and cutting expertise is continually improving. From the initial use of lasers, contemporary technology, in particular CNC, has enabled amplified precision and cost-effective laser cutting, making it one of the most accepted cutting practices. Liable on the strength, laser technology can cut soft metal up to 12.7 millimetres of thickness, inox of 10 millimetres maximum thickness. The maximum metal thickness that can be cut with a laser is 25 mm for stainless steel, and 15 mm for aluminium.
Laser CNC sheet metal cutting is most frequently used for cutting standardized structure metals, while impurities and intermixtures greatly decrease the quality of the cut. In addition to decreasing quality, fused metal resulting in an unavoidable cutting product can harm the lens of the laser. Today, in practice, there is a mounting need for cutting very thin constituents necessitating additional operations during the process. Since of the low material width, it is necessary to channel the heat consequential from the cutting process. Laser cutting is used in cutting numerous metal types and different widths.
