Introduction
In industrial production, numerical control system is essential in machine tool, as it can control the movement of the cutting tools according to the instructions given. It can greatly improve the quality, accuracy and efficiency of the production process. In order to get the best performance of machine tool, the selection of numerical control system is very important. This article will discuss the topics including the types of numerical control system, the typical components and the selection criteria of numerical control system.
Types of Numerical Control System
There are several different types of numerical control systems, but the basic function of each of them is the same. Generally, there are three types of numerical control system: point-to-point, contouring and machining.
Point-to-point machine is the simplest type of numerical control system and it only allows movement that is in a straight line. This type of system is usually used for tasks such as drilling where the movement is very simple.
Contouring machine has more complex control systems and can also move the cutting tools in arcs and circles. This type of system is usually used for tasks such as machining, where the movement is more complex.
Machining type of system is the most advanced type of numerical control system. It can execute the commands faster, more accurately and in more complex paths. This type of system is usually used for tasks such as milling, where the movement is very complex.
Typical components of Numerical Control System
Numerical control system mainly consists of three components: software, hardware and peripheral devices.
The software component of a numerical control system includes the computer programming language, which can be used to write the program that can control the machine tool. Most of the language used is G code, which is widely used in the industry.
The hardware component of a numerical control system mainly includes a central processing unit and an internal power supply. The central processing unit can receive the program and send the instructions to the machine tool. The internal power supply can supply the power to the hardware component of the system.
The peripheral devices in a numerical control system include the motors and actuators that can move the cutting tools, the sensors that can detect the position and the speed of the cutting tools, and the drives that can control the movement of the cutting tools.
Selection Criteria of Numerical Control System
There are several criteria that should be taken into account when selecting the numerical control system.
The first criterion is the accuracy required. The accuracy of the machine tool and the machining process depend on the accuracy of the numerical control system. So, the higher the accuracy required, the higher the accuracy of the numerical control system should be.
The second criterion is the speed. The speed of the machining process depends on the speed of the numerical control system. A faster system will allow the machine tool to perform tasks faster.
The third criterion is the types of machine tool. Different types of machines require different types of numerically controlled systems. For example, a milling machine and a turning machine require different types of numerical control system.
The fourth criterion is the scalability. The scalability of a numerical control system determines how much control the user can have over the machine tool. A scalability system will allow the user to have more control over the machining process.
Conclusion
In conclusion, numerical control system is essential in machine tool, as it can control the cutting tools according to the instructions given. In order to get the best performance of the machine tool, it is important to choose the right numerical control system. The selection of a numerical control system should take into account the accuracy, speed, type of machine tool and scalability of the system.
