A key goal of CAD/CAM is to produce data that can be used in manufacturing a product while developing the data for the design of that product. When successfully implemented, CAD/CAM involves the sharing of a common database between the design and manufacturing components of a company.
With the advent of computer technology, manufacturing
professionals have wanted to automatic the design process and use the database developed therein for automating manufacturing processes．Computer-aided design/computeraided manufacturing (CAD/CAM), when successfully implemented, should remove the “wall” that has traditionally existed between the design and manufacturing components:

数控专业的英语作文
数控专业的英语作文Computer Numerical Control: Revolutionizing Manufacturing.In the realm of manufacturing, computer numerical control (CNC) has emerged as a transformative technology, revolutionizing the way products are designed, produced, and inspected. CNC machines, guided by precise computer instructions, have brought about a quantum leap in efficiency, precision, and automation. This article delves into the multifaceted world of CNC, exploring its history, principles, applications, and impact on modern manufacturing.Historical Origins and Evolution.The roots of CNC can be traced back to the 1940s, when numerical control (NC) machines were developed by John T. Parsons to automate aircraft manufacturing processes. These early NC machines employed punched tapes to storeprogrammed instructions, which controlled the movements of machine tools.In the 1950s and 1960s, the advent of computers led to the development of CNC machines, where computer programs replaced punched tapes. This technological leap enabled more complex and precise control over machine operations, paving the way for increased efficiency and reduced production time.Principles of CNC.CNC machines operate based on a set of principles that enable them to execute precise and automated manufacturing operations:Computer-Aided Design (CAD): CAD software is used to create digital models of products, which are then translated into CNC code.G-Code and M-Code: CNC code, typically in G-code and M-code formats, provides detailed instructions on themovements, speeds, and other parameters of the CNC machine.Controllers: CNC controllers interpret the coded instructions and send commands to the machine motors and actuators, controlling the machine's operations.Feedback Systems: Sensors and encoders provide real-time feedback to the controller, ensuring accurate positioning and control of the machine.Applications of CNC.CNC machines have found widespread applications across various manufacturing industries, including:Aerospace: Precise machining of aircraft components, engine parts, and other critical components.Automotive: Manufacturing of engine blocks, gearboxes, and other automotive parts with high precision and repeatability.Medical: Production of medical implants, surgical instruments, and prosthetic devices with intricate geometries.Electronics: Fabrication of circuit boards, electronic components, and precision electronic devices.Prototyping and Rapid Manufacturing: Rapid prototyping and small-scale manufacturing of prototypes, custom products, and low-volume production runs.Impact on Modern Manufacturing.CNC technology has had a profound impact on modern manufacturing practices, transforming processes and driving innovation:Increased Productivity: Automation reduces human intervention, enabling continuous production and higher throughput.Improved Precision: Computer-controlled machinesachieve extremely high levels of precision, leading to improved product quality and reduced scrap rates.Flexibility and Customization: CNC machines can be easily reprogrammed for different products, allowing for rapid changes in production and customization of products.Reduced Lead Times: Automated production and reduced setup times shorten lead times, enabling faster delivery to customers.Skilled Workforce: CNC technology requires trained operators with specialized skills, fostering a highly skilled workforce.Conclusion.Computer numerical control (CNC) has revolutionized manufacturing by automating processes, improving precision, increasing productivity, and providing flexibility. The integration of CNC technology has transformed the way products are designed, produced, and inspected. Asmanufacturing continues to evolve, CNC will remain a cornerstone technology, enabling manufacturers to meet the demands of the 21st century and beyond.。

数控技术英语作文
数控技术英语作文English:Numerical Control (NC) technology, also known as Computer Numerical Control (CNC), is a revolutionary advancement in manufacturing processes. It integrates computer systems with machinery to control and automate various operations such as cutting, milling, drilling, and shaping of materials with unparalleled precision and efficiency. One of the key components of NC technology is the CNC machine, which operates based on coded instructions programmed into the computer system. These instructions dictate the movements and actions of the machine's tools, allowing for highly accurate and complex manufacturing tasks to be carried out consistently. NC technology has transformed the manufacturing industry by significantly reducing production times, minimizing errors, and enabling the production of intricate components that were previously unattainable. Moreover, CNC machines can be easily reprogrammed to accommodate changes in production requirements, offering manufacturers greater flexibility and adaptability in responding to market demands. With continuous advancements in software and hardware, NC technology continuesto evolve, pushing the boundaries of what is achievable in modern manufacturing processes.中文翻译：数控技术，也称为计算机数控（CNC），是制造过程中的一项革命性进步。
