Side Visibility Moon’s Arcturus Auto Rear Light comes with a specially adapted lens and LED system which spreads the light emitted so that not only will you stay visible from the rear but also from the sides. Staying visible from multiple angles is important when cycling through built up urban areas where you’re often find yourself traversing multiple lanes and directions of traffic. Durable Construction Built for multiple types of environment the light comes with a rugged casing construction that is made from heat sinking CNC aluminium. This housing will protect against impacts as well as having an IPX4 certification which will also shield against rain, dust, dirt, road spray, and more. Rechargeable Keep going for longer with a lithium polymer battery which is rechargeable and comes with a water-resistant USB cable which makes charging on the go easier than ever allowing you to charge the light via any standard USB port. The light’s battery comes with up to 17 hours of battery life and takes just two hours to recharge with a useful battery light indicator to tell you when it’s time to charge and when your battery is fully charged. Also, to save your battery life when the light’s not in use the light automatically turns itself on and off due to light sensors. Light Modes The rear light comes with a large selection of light modes including stationary and flashing which are easy to toggle between to find the best possible light mode for your current lighting environment and depleting battery life. The light modes included: Mode One: 10 lumens light output – 3.45 hours battery life Mode Two: 15 lumens light output – 2.20 hours battery life Mode Three: 35 lumens light output – 1.20 hours battery life Flash One: 10 lumens light output – 17 hours battery life Flash Two: 35 lumens light output – 5 hours battery life Flash Three: 35 lumens light output – 8 hours battery life Day Flash: 70 lumens light output – 16.30 hours battery life In the Box Arcturus-Auto Pro rear light RB-22 (Universal bracket) 2 O-rings for mounting (including 20-35/35-52mm) BK-21 (Belt clip) USB-WP (Water resistant USB cable)

Rapid Prototyping is fast becoming one of the essential technologies that allow manufacturers to improve product quality and reduce both times to market and the cost of new lines. RP helps quickly fine tune the designs from concept to functional prototype that can cut product development schedule to weeks or months. A generative process planning system for parts produced by Fused Deposition Modeling is discussed. Process planning for RP involves optimal selection for orientation of model with a proper support structure and it requires an intelligent slicing methodology, direct or adaptive to minimize the built up time by keeping the geometry and cusp height errors in control. Pre and post slicing processes have been used to minimize the sliced data error. The CAPP model involves seven modules and it has been implemented in C language using a unique methodology. A set-up is being designed to fuse and extrude the FDM wire and it is being used in place of the spindle of a CNC milling machine. The proposed work can also be used for metal to be deposited and the whole set-up costs very less as compared to the commercial counterparts.

Nowadays, the application of artificial techniques is present in various fields as well as in the manufacturing industries. This Book offers the applications of Artificial Techniques available for programming of CNC Machine Tools. Offers clear description for different problems of Intelligent CNC machine tools, such as tool path length, tool selection, optimization of machining parameters. Also, in this book are explain the problems for linear, circular and spline interpolation. As another problem, is developed as model for flexible manufacturing system including such as: saw, lathe, boring, milling and grinding CNC machine tools. Except, of main problems in this book are obtained and analyzed some other problem with help of the Artificial Intelligence for investigation of cutting force, surface roughness, measurement of tool wear. Mathematical model is implemented into the Multi-objective Genetic Algorithm to solve the problem as case of study in this book. Discrete machining is applied to solve the problem for turning workpiece where each square present the sequence of machining process, and cutting force is depended from the depth of cut and geometry of workpiece using Matlab.

This book is a study about the critical components of CNC machine. As performance of CNC machine great depends on its main or critical components i.e. spindle and ballscrew, and this performance is interrelated with machine tool and machining process. Initially we take spindle for analysis in this report. For analyzing force we take most common process perform on CNC machine say drilling process and turning, in which torque and thrust force is generated, and this force calculated by mathematical modeling. Using this torque and thrust force we are analyzing in ANSYS 13.0 Workbench software. These software gives the most preciously result in analysis and optimization point of view. As the critical components like spindle and ballscrew is to be analyzed for that stress analysis, total deformation and maximum shear stress is carried out in the software. Using this FEA analysis optimization of spindle is being done. And another critical component of CNC machine i.e. ballscrew is analyzing and further checking their acceptability whether it is working within permissible limits or not. And also selection methodology of ballscrew and service life is to be calculated.

Optimization of a 2.5D milling process is generally considered to be one of the most significant issues for high-speed machining during mass production to amplify productivity and quality of production. Total time spent during 2.5D milling primarily comprises of productive and non-productive time. The productive time, cost and quality of production is highly influenced by machining parameters such as cutting speed, feed rate, width of cut (step over), depth of cut, tool diameter etc. Also selection of optimal machining conditions for better machining process efficiency is one of the key factors for this problem. The objective of the present work is to identify and organize the controllable variables such that there is minimum effect of uncontrollable or noise variables on the process performance. The machining processes which maintain balance between cost and quality of production are presumed to be efficient. The movements of tool are synchronized with the help of automatically generated CNC codes. In the present work an attempt also been made on minimization of non-productive time by synchronizing cutting tool movements for malti pockets job problems.

'Metal cutting is a widely used method of producing manufactured products. The technology of metal cutting has advanced considerably along with new materials, computers, and sensors. This new edition treats the scientific principles of metal cutting and their practical application to manufacturing problems. It begins with metal cutting mechanics, principles of vibration, and experimental modal analysis applied to solving shop floor problems. Notable is the in-depth coverage of chatter vibrations, a problem experienced daily by manufacturing engineers. The essential topics of programming, design, and automation of CNC (computer numerical control) machine tools, NC (numerical control) programming, and CAD/CAM technology are discussed. The text also covers the selection of drive actuators, feedback sensors, modeling and control of feed drives, the design of real time trajectory generation and interpolation algorithms, and CNC-oriented error analysis in detail. Each chapter includes examples drawn from industry, design projects, and homework problems. This book is ideal for advanced undergraduate and graduate students, as well as practicing engineers'--Provided by publisher.
