Articles on CNC machining

Here you can find articles with general information on CNC machining, machined parts design, engineering, technology and more!

There is variability in any manufacturing process and, as such, tolerances are used to set permissible limits on this variability.

In this article we’ll go over some of the top tips on how you can improve your designs and decrease cost while optimizing your parts for manufacturing using CNC machining.

The machine tool spindle provides the relative motion between the cutting tool and the workpiece which is necessary to perform a material removal operation.

A tool holder for milling has three main parts: the taper, the flange and the collet pocket. The taper is the conical part that is introduced into the spindle.

The quality of a machined surface is becoming important to satisfy the increasing demands of component performance and reliability.

An engineering perspective on precision manufacture necessarily looks to a continuing refinement of machining and processing techniques for the overall improvement of products.

Milling is a machining operation in which a workpart is fed past a rotating cylindrical tool with multiple cutting edges (occasionally, a tool with one cutting edge, called a fly-cutter, is used). The axis of rotation of the cutting tool is perpendicular to the direction of feed.

Turning is a machining process in which a single-point tool removes material from the surface of a rotating workpiece. The tool is fed linearly in a direction parallel to the axis of rotation to generate a cylindrical geometry.

A machining center is a highly automated machine tool capable of performing multiple machining operations under computer numerical control (CNC) in one setup with minimal human attention.

The wrought alloy designation system consists of four numerical digits, sometimes preceded by a capital letter. The first digit indicates the principal alloying elements, as described next; the second digit is the variation of that alloy; and the last two digits represent the specific alloy designation.
