It provides information on different machine tools, machining centers, transducers and controllers used in manufacturing. Cutting speed and feed rate tables are included for a variety of materials.
Unconventional machining processes remove material from a workpiece using energy-based techniques rather than direct contact cutting tools. They are used for hard and brittle materials that are difficult to machine with conventional tools. Unconventional processes are classified based on the type of energy used, such as mechanical, electrical, electrochemical, chemical, or thermo-electrical. Examples include electrical discharge machining, which uses electric sparks, and abrasive jet machining, which uses a high-velocity abrasive stream. These processes allow harder materials to be machined with higher accuracy and surface finish compared to conventional techniques.
This document discusses different types of hydraulic pressure control valves. It describes pressure relief valves, pilot operated relief valves, sequence control valves, and other types.

Capstan and turret lathes are production lathes used to manufacture large quantities of identical parts quickly. Unlike engine lathes, they do not have tail stocks and can hold multiple tools that operate simultaneously. Capstan lathes have hexagonal turrets mounted on slides that move longitudinally, while turret lathes have stationary hexagonal turrets mounted directly on the saddle. Both types of lathes are suited for machining bars and irregular workpieces, with turret lathes able to accommodate heavier work. Common tooling includes box, flanged, and slide tool holders that mount to the turrets.

Chapter 2 constructional feature of cnc machineRAHUL THAKER
This document discusses the constructional features of CNC machines. It classifies CNC systems according to the type of machine into point-to-point, straight-cut, and continuous path systems. It also categorizes them based on programming method as absolute or incremental, and by control system type as open-loop or closed-loop. Point-to-point systems move in straight lines for operations like drilling. Continuous path systems enable contouring for milling complex profiles. Programming specifies tool movements, and feedback loops help verify final positions match programs. Common machine elements include motors, ball screws, and feedback devices.
The document discusses static and dynamic balancing of rotating masses. Static balancing ensures the center of gravity remains stationary during rotation by balancing out centrifugal forces in any radial direction. Dynamic balancing prevents vibration during rotation by statically balancing and also balancing out moments and couples involved in accelerating moving parts. The types of balancing are defined as static, where forces due to gravity are balanced, and dynamic, where inertia forces are balanced in addition to static balance. Benefits include reduced vibration, noise, stresses, and increased quality, bearing life, and efficiency. Balancing is necessary to prevent problems from vibration like noise, abrasion, and shortened machine life.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
