C lassification of NC & CNC Technology By: M. KAMALA KANNAN ( 211231101603) 3 rd year, Robotics and Automation
NC Technology: Numerical control (NC) technology is the automated control of machining tools by means of a computer. It is a broad term that encompasses a wide range of systems, from simple point-to-point machines to complex multi-axis CNC machines.
There are many different ways to classify NC technology: By motion control: NC systems can be classified as point-to-point(PTP) or contouring systems. PTP systems control the position of the tool at discrete points, while contouring systems control the path of the tool as it moves along a continuous curve. By control loops: NC systems can be classified as open-loop or closed –loop systems. Open-loop systems do not provide feedback to the controller, while closed-loop systems do. This means that closed-loop systems are more accurate than open loop systems.
By power supply: NC systems can be classified as hydraulic, electric, or pneumatic. Hydraulic system use fluid pressure to move the machine tools, electric systems use electrical motors, and pneumatic systems use compressed air. By manufacturing method: NC systems can be classified as universal or dedicated. U niversal systems are designed to be used with a wide range of machine tools, while dedicated systems are designed for a specific type of machine tool.

CNC Technology: CNC stands for computer numerical control. It’s a technology that uses computerized systems to control machine tools and equipment. CNC technology allows for precise and automated machining processes, making it widely used in manufacturing industries for tasks like cutting, milling, drilling, and lathing. It enhances efficiency, accuracy, and repeatability in production processes.
There are many different ways to classify CNC technology: By number of axes: CNC machines can be classified by the number of axes that they control. The most common CNC machines are three-axis machines, which control the X, Y, and Z axes. However, there are also four-axis, five-axis, and even six-axis CNC machines. By type of machine: CNC machines can also be classified by the type of machine that they are. Some common types of CNC machines include milling machines, lathes, grinders, and plasma cutters.
By control system: CNC machines can also be classified by the type of control system that they use. The most common control systems are point-to-point(PTP) and contouring. PTP system control the position of the tool at discrete points, while contouring systems control the path of the tool as it moves along a continuous curve. By application: CNC machines can also be classified by the application that they are used for. Some common applications for CNC machines include manufacturing, prototyping, and repair. By cost: CNC machines can also be classified by their cost. CNC machines can range in price from a few thousands dollars to several hundred thousands dollars.
