How long does CNC machining take for parts

As an important process in the field of modern manufacturing, CNC machining has been widely used in all walks of life to realize the manufacture of precision parts through intelligent control of computers. During the manufacturing process, the complexity of the part has a great impact on the machining time.

Why it's important to know the cnc machining time for parts?

• It is important to know the CNC machining time for parts for a number of reasons as below:

• Cost estimation: CNC machining time is a major factor in determining the cost of a machined part. By knowing the machining time, you can more accurately estimate the total cost of the part.

• Production planning: CNC machining time is essential for planning production schedules. If you know how long it takes to machine each part, you can schedule production accordingly to ensure that parts are delivered on time.

• Quality control: CNC machining time can also be used for quality control purposes. By tracking the machining time for each part, you can identify any parts that are taking longer to machine than expected. This may indicate a problem with the part design, the material, or the machining process itself.

  
  

Now let's explore the time required for CNC machining from the perspective of simple geometries to highly complex structures, and deeply analyze the influence of geometry, machining process and related parameters on machining time. Through the analysis of the machining time of parts of different complexity, we can better understand the essence of CNC machining and provide useful guidance for decision-making and optimization in the manufacturing industry.

Simple parts with large tolerances.

For simple parts such as basic geometries such as nuts, bolts, pins, cylinders, retaining rings, flat washers, cuboids, etc., the machining time is relatively short. The geometry of these parts is relatively simple and usually requires only a few faces. Because the cutting path is relatively straight, the machining program is easier to write, and the machine can complete the cutting operation relatively quickly. Typically, a simple part may be machined in tens of seconds to minutes, depending on the setting of parameters such as cutting speed, feed speed and depth of cutting: as the complexity of the part geometry increases, for example; Gears, cams, crankshafts, connecting rods. The machining time increases accordingly.

Moderately complex parts.

Moderately complex parts may have multiple surfaces, holes, slots, and other features that require more cutting operations. Machining such parts requires more complex machining programs and more tortuous cutting paths. During the machining process, it may be necessary to change the tool and head several times to adapt to different cutting needs, which will increase the total machining time. Typically, the machining time of moderately complex parts can be between minutes and tens of minutes with tight tolerances for highly complex parts: the machining of highly complex parts involves more technology, processes and equipment, requiring advanced machining technology and expertise to ensure the performance, precision and reliability of the final product.

Highly complex parts with tight tolerances.

The machining of highly complex parts involves more technology, processes and equipment, requiring advanced processing technology and expertise to ensure the performance, precision and reliability of the final product. These components are often used in high-tech applications such as; Turbine blades, complex parts of spacecraft, precision instrument parts, medical implants, etc. Therefore, there are higher requirements for precision and precision in the manufacturing process. The machining process may require multi-axis synchronous movement to complete, this type of part processing time is longer, because the writing of the machining program is very complicated, it is necessary to consider the coordination of multi-axis motion and the selection of cutting tools and the optimization of cutting data. Multiple tool changes, cutting fluid spraying, etc. may also be required during machining to ensure machining quality and precision. The machining time for highly complex parts can range from tens of minutes to hours or even longer.
