CNC Machining

CNC machines are automated motorized machine tools operated by programmed numerical control (NC) commands, as opposed to controlled manual hand-wheels and levers. The first (computer numerical control) CNC machines were produced in 1940, and have rapidly advanced in design and capability along with the engineering technology over the last 70+ years, and now include an end-to-end component design using computer aided design (CAD) and computer aided manufacturing (CAM) programs. Modern CNC machining entails the use of different drills, end mills and other tooling, requiring a combination of customized multiple tooled equipment and machines, and automated and operator workflow processes, in order to produce precision parts that meet the exact requirements of the original CAD design and specifications. CNC machining has the advantage of improved efficiency, productivity and accuracy over other forms of machining. CNC machined parts are more easily produced to tight tolerances in a production process. Family owned and operated, Dynamic Precision Products, Inc. is located in the Village of Wauconda, Illinois, and has been precision machining parts (made in the USA) since 1978. Our state-of-the-art facilities include 25 CNC lathes and CNC mills, including: Kitamura

CNC machining centers, Mori Seiki, Daewoo Puma, Hardinge, and Tsugami CNC Swiss lathes. For a complete equipment listing, click here.

What is CNC?

Computer Numerical Control (CNC) refers to the automation of mac

hine tools that are operated by programmed commands encoded on a computer software program, as opposed to manually controlled via hand wheels or levers, or automated via cams. These servomechanisms were augmented with digital and analog computers and have revolutionized the machining process.

In modern systems, component design is highly automated using computer-aided design (CAD) and computer aided manufacturing (CAM) programs. The programs produce a file that gets has the commands interpreted to a particular machine via a postprocessor (for a

specific controller), and then get loaded into a CNC machine for production. Most modern CNC machines have tool carousels for loaded multiple types of tooling to perform the required machining such as spotting drills, drills, reamers, boring bars, end mills, etc. The complex series of steps required to produce a part are highly auto

mated and produces a part in a fraction of the time required to produce that part manually. Parts produced are all closely repeatable with minor corrections needed due to

tool wear along the way.
