This document provides an introduction to computer numerical control (CNC) technology and metal cutting. It discusses the history of CNC development from the first numerically controlled machine in 1949 to modern CNC machines found in many industries today. The key components of a CNC system are described, including the part program, program input device, machine control unit, drive system, machine tool, and feedback system. Common CNC machine tools and their applications in industries like automotive and aerospace are also outlined.
This document discusses CNC milling and provides information on:
1. CNC milling uses a prepared program to control the functions and motions of a machine tool.
2. The benefits of CNC milling include high accuracy, short production time, and reduced human error. The drawbacks include high costs and maintenance.
3. It describes various milling operations like profile, drilling, pocket milling, and mirroring operations. It also discusses G-codes and M-codes used in CNC programming.
CNC machines use position feedback devices like encoders and potentiometers to provide information to the control system on the position of the machine axes. Encoders convert linear or rotational position into an electrical signal and come in various types like optical or magnetic. ISO and EIA standards define common programming languages used to operate CNC machines manually or through CAM software. Proper integration of CAD, CAM, and CNC programming is needed to efficiently manufacture parts.
This document provides an overview of CNC control systems. It discusses that CNC machines use open loop and closed loop control systems to position tools and axes based on programmed instructions. Closed loop systems incorporate feedback to monitor the output and correct any discrepancies. Feedback can be provided through linear scales or encoders. The document also examines hardware and software interpolation methods used to generate intermediate positioning points along tool paths between programmed coordinates. Finally, it outlines some key features, advantages, and limitations of CNC machines.
The document provides an overview of manufacturing systems. It defines a manufacturing system as consisting of inputs, transformation processes, and outputs. The key components of a manufacturing system are identified as production machines, material handling systems, computer control systems, and human resources. Production machines are classified as manually operated, semi-automated, or fully automated. Material handling functions include loading, positioning, unloading, transporting parts between stations, and temporary storage. Computer control systems manage instructions, part programs, material handling, scheduling, and quality control. Human workers perform value-added work and support automated systems. Manufacturing systems are also classified based on their operations, number of workstations, layout, automation level, and product variety.
This document discusses CNC machine tools used for metal removal processes like grinding. It describes the components and functions of CNC machines, including the coding, drive system, machine tool, and feedback system. It also explains the motion of grinding wheels, types of workpieces and operations in grinding, use of recirculating ball screws for table movement, and how stepper motors are used to control the axis of rotation and downfeeding of grinding wheels.
The document provides an overview of computer aided manufacturing (CAM) and computer numerical control (CNC) machines. It discusses the history of CNC development from the first numerically controlled machine in 1949 to widespread use today. It describes the basic components and functioning of CNC machines, including numerical control systems, axis drives, part programs, and feedback systems. It also covers different types of CNC machines, control methods, and industries that utilize CNC technologies like automotive and aerospace.
This document discusses the components and design considerations of computer numerical control (CNC) hardware. It describes the structure of CNC machine tools, including rigid beds, spindles, spindle drives, feed drives, and feedback control systems. Specific topics covered include stepper motors, servo motors, lead screws, ball screws, linear motors, encoders, and tooling systems. The goal of the design elements discussed is to enable CNC machine tools to achieve high stiffness, accuracy, and speeds for precision machining applications.
This document discusses the components and workings of CNC machines. It begins by explaining numerical control machines and their evolution into CNC machines, which are controlled by a microcomputer rather than hardwiring. The main electrical components of CNC machines are stepper motors and servo motors. Stepper motors move in discrete steps while servo motors use feedback control. Mechanical components include recirculating ball screws and roller screws which convert sliding motion to rolling motion for precision positioning.
