2. List of blade materials - Wikipedia

   en.wikipedia.org/wiki/List_of_blade_materials

   A wear-resistant, martensitic stainless tool steel that exhibits better corrosion resistance than 440C stainless steel. 2Cr13, belongs to 420 grade series, very basic. EN 1.4021 / DIN X20Cr13, widely used in economic cutting tools, 50HRC max after heat treatment.

3. Machinability - Wikipedia

   en.wikipedia.org/wiki/Machinability

   Machinability is the ease with which a metal can be cut permitting the removal of the material with a satisfactory finish at low cost. [1] Materials with good machinability (free machining materials) require little power to cut, can be cut quickly, easily obtain a good finish, and do not cause significant wear on the tooling.

4. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

5. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   The average carbon footprint of stainless steel (all grades, all countries) is estimated to be 2.90 kg of CO 2 per kg of stainless steel produced, [97] of which 1.92 kg are emissions from raw materials (Cr, Ni, Mo); 0.54 kg from electricity and steam, and 0.44 kg are direct emissions (i.e., by the stainless steel plant). Note that stainless ...

6. Surface feet per minute - Wikipedia

   en.wikipedia.org/wiki/Surface_feet_per_minute

   SFM is a combination of diameter and the velocity of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 surface meter per second (meter per second, or m/s, is the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.

7. Grinding (abrasive cutting) - Wikipedia

   en.wikipedia.org/wiki/Grinding_(abrasive_cutting)

   Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

8. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   It specifies the form of the cutting edge. 1 means a symmetric cutting edge. If the value is smaller than 1 the form is called a waterfall. If the value is larger than 1 it is called a trumpet. Depending on the material being cut, feed rate and other factors, a cutting tool with the optimum K factor should be used.

9. Rake angle - Wikipedia

   en.wikipedia.org/wiki/Rake_angle

   In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative. Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner side.
