The difference between NC and CNC

Block processing time and others. Due to the increase in CPU processing speed and the application of high-speed CPUs by CNC manufacturers to highly integrated CNC systems, the performance of CNC has been significantly improved. A more responsive and sensitive system achieves more than just higher processing speeds. In fact, a system that can process parts processing programs at a relatively high speed may also behave like a low-speed processing system during operation, because even a fully functional CNC system has some potential problems, which may become limitations. The bottleneck of processing speed.

At present, most mold factories realize that high-speed machining requires more than just a short processing time. In many ways, this situation is similar to driving a car. Will the fastest car win the race? Even an occasional spectator who watches a car race knows that in addition to speed, there are many factors that affect the outcome of the race.

First of all, the driver’s knowledge of the track is important: he must know where there is a sharp turn so that he can decelerate appropriately and pass the curve safely and efficiently. In the process of machining molds at high feed rates, the CNC's track monitoring technology to be processed can obtain information about the appearance of sharp curves in advance, and this function plays the same role.

Similarly, the driver's sensitivity to other driver actions and uncertain factors is similar to the number of servo feedback in CNC. The servo feedback in CNC mainly includes position feedback, speed feedback and current feedback.

When the driver drives around the track, the continuity of the action and the ability to brake and accelerate proficiently have a very important impact on the driver's on-site performance. Similarly, the CNC system’s bell acceleration/deceleration and processing track monitoring functions use slow acceleration/deceleration to replace sudden speed changes to ensure smooth acceleration of the machine tool.

In addition, there are other similarities between racing cars and CNC systems. The power of a racing car engine is similar to that of a CNC drive and motor. The weight of a racing car can be compared with the weight of a moving component in a machine tool. The stiffness and strength of a racing car are similar to those of a machine tool. The CNC's ability to correct specific path errors is very similar to the driver's ability to control the car in the lane.
