What Is CNC ?

Computer numerical control (CNC) is the automation of machine tools by means of computers executing pre-programmed sequences of machine control commands. This is in contrast to machines that are manually controlled by hand wheels or levers, or mechanically automated by cams alone.

In modern CNC systems, the design of a mechanical part and its manufacturing program is highly automated. The part's mechanical dimensions are defined using computer-aided design (CAD) software, and then translated into manufacturing directives by computer-aided manufacturing (CAM) software. The resulting directives are transformed (by "post processor" software) into the specific commands necessary for a particular machine to produce the component, and then are loaded into the CNC machine.

Since any particular component might require the use of a number of different tools – drills, saws, etc. – modern machines often combine multiple tools into a single "cell". In other installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD.

Excel Formulas and Functions: Step-By-Step Guide with Examples
Excel Power Query: Excel for Beginners
For many of us, Excel is nothing more than a basic spreadsheet, something we may use on the odd occasion, but for some, it is part of our daily lives. Microsoft Excel is more than just a spreadsheet; it is an essential tool for businesses. In fact, it would be fair to say that it is probably one of the most important tools that a business could have at its disposal. Some of the best uses for Excel include extracting data into charts, using it to identify problems and trends, bringing all the data together from multiple files and other sources so it’s all in one easy-to-use place and much more.

  • Covers both digital and analog signals
  • An indispensable resource for tech writers, marketers, managers, and other nonengineers


The Complete DSP Guide for Businesspeople and Nontechnical Professionals

Digital signal processing (DSP) technology is everywhere–each time you use a smartphone, tablet, or computer; play an MP3; watch a digital TV or DVD; get GPS directions; play a video game; take a digital photo; or even have an MRI, DSP technology is at work.

Now, for the first time, The Essential Guide to Digital Signal Processing offers readers of all levels simple, plain-English explanations of digital and analog signals and modern DSP applications. Whether you sell technology, write about it, manage it, fix it, or invest in it, this is the book for you.


Using everyday examples and simple diagrams, two leading DSP consultants and instructors completely demystify signal processing. You’ll discover what digital signals are, how they’re generated, and how they’re changing your life.


You’ll learn all you need to know about digital signal collection, filtering, analysis, and more, and how DSP works in today’s most exciting devices and applications.


Coverage includes
  • How engineers understand and work with analog signal spectra and frequencies
  • How digital signals are generated and used in modern electronic devices
  • The surprising things that happen when analog signals are converted to digital form
  • How (and why) engineers compute digital signal spectra with Fourier transforms
  • What wavelets are and how they’re used everywhere, from medicine to the camera in your smartphone
  • How digital filters are used in DSP applications
  • Cutting-edge DSP applications, from automatic music-tuning software to medical EKG signal analysis
  • A comprehensive glossary of signal processing terminology and acronyms

  • You’ll gain a clear, conceptual understanding of all key signal processing operations and vocabulary. That means you’ll understand much of the “magic” built into today’s newest devices, and you’ll be ready to succeed in virtually any nontechnical role that requires DSP knowledge.
