Electrical Discharge Machining (EDM) | Modern Machine Shop
Jul 10, 2021 · Electrical discharge machining, or EDM, is a non-contact process that can machine parts regardless of their hardness. It involves placing an electrode or wire and an electrically conductive workpiece into a circulating dielectric fluid. The fluid acts as an insulator until a specific spark gap and voltage ionizes it and enables a spark to ...
A New Milling 101: Milling Forces and Formulas
Mar 21, 2011 · MRR = .200 x 1.64 x 19.5 = 6.4 in3/min. For horsepower at the motor (HPm), use formula: HPm = HPC/E. In determining horsepower consumption, “K” factors must be used. The “K” factor is a power constant that represents the number of cubic inches of metal per minute that can be removed by one horsepower.
Workholding | Modern Machine Shop
Aug 29, 2022 · Workholding. Workholding refers to any device that is used to a secure a workpiece against the forces of machining. The most basic workholding device is a simple clamp, but workholding can also involve complex fixtures that are custom-built for particular parts.
Properly Reading Dial Indicators | Modern Machine Shop
May 6, 2021 · Most dial indicators are then used in a comparative mode using a balanced dial, with minus (-) readings on the left of 0 and plus (+) readings to the right of 0. The goal is that the plus and minus tolerances are in the range of the 10 and 2 o’clock positions on the dial. There are also large-approach and over-tolerance ranges to see the work ...
Choosing The Right Grinding Wheel | Modern Machine Shop
Dec 15, 2000 · Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.
Cutting Tools | Modern Machine Shop
Oct 28, 2024 · Cutting Tools. The broad category of “cutting tools” includes all of the consumable tooling involved in milling, drilling, turning and other lathe and machining center operations. Drills, end mills, taps, reamers and inserts are all included here. Consumable tooling used on certain other types of machine tools is included here as well.
Machining 101: What is Grinding? | Modern Machine Shop
Jul 3, 2021 · Evan Doran. Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece’s surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

Grinding | Modern Machine Shop
Aug 12, 2022 · Grinding. Grinding is a machining process that takes a very light “cut” using abrasive media—typically an abrasive grinding wheel. Grinding wheels with different grit sizes achieve rougher or finer grinding passes, according to the needs of the application. When precise accuracy and/or surface finish are required, grinding is often used ...
