Machine tools are devices that are used to shape metals and other material. These tools are used for grinding, drilling, boring, cutting and other processes that are used to shape metals. Numerical control involves using control devices that can automate the operations of the machine tools in industrial environments. These machines can be manual or completely automated. Over the last few decades, the trend has been towards the use of Computer Numerical Control (CNC) devices that are fully automated control machines.
Machine Tool Design And Numerical Control covers the subject of designing machine tools and controlling them through different kinds of numerical controllers. The material in this book is divided into nine chapters. The book begins with an Introduction to Machine Tool Drives and Mechanisms. This chapter covers the general principles of machine tool design. The second chapter covers the Regulation of Speed and Feed rates in machine tools. It explains feed boxes, gear box design and kinematics of machine tools.
The third chapter looks at the Design of Machine Tool Structures. This chapter goes into the functions that a tool needs to perform and the design criteria that defines the structure of such tools. It also looks at the various structural elements of the machine tool like ribs and stiffeners. The next chapter focuses on the Design of Guide Ways and Power Screws. It examines the functions and types of guideways and the design of power screws. The fifth chapter is on the Design of Spindles and Spindle Supports.
The sixth chapter covers the Dynamics of Machine Tools. It discusses the machine tool as a closed loop system where the Machine Tool Elastic System and the Cutting Process (MTES & CP) interact with each other. It also goes into various cutting force models and stability analysis. The next chapter begins the coverage of Control Systems in Machine Tools. It examines manual and automatic control systems. The eighth chapter discusses Numerical Control of Machine Tools. It covers manual and computer aided part programming. The final chapter covers the Extensions of Numerical Control. It looks at Computer Numerical Control (CNC) machine tools and Direct Numerical Control (DNC) machine tools, with special focus on CNC systems.
As a design manager, I am acutely aware of how important it is to have the right tools at hand to help complete a project. After all, it is my job to design some of the most powerful and accurate portable machine tools for use in plant maintenance and production processes around the world.
While the powerful and sophisticated CAD software is the bread and butter tool for our trade, good machine designers shouldnt rely on software alone. I could not be without the humble sketchpad, calculator, and pencil. Almost all of our initial designs are hand-drawn before they make it to the 3D CAD system.
In my opinion, the team at SolidWorks really grasps what machine designers need and have packaged it into user-friendly interface. The additional features such as the cost estimate and quoting tools help us deliver projects on budget, while files we export can easily be turned in to stunning 3D animations such as this: 2ff7e9595c
