    Technological process route

    The technological process route is also referred to as the production route, in other words, a work plan, a detailed structured description of activities within the technological process. A technological process route describes the sequence of actions necessary to produce a part, machine or device. The full description of the production route includes the individual…

    Hadfield steel cutting speed – milling

    As I wrote in the article Hadfield Steel, prison steel, milling, the aforementioned steel grade is difficult to machine. This is due to the specific austenitic properties of high manganese steels (Hadfield steels). These steels have very high tensile strength (from 350 to 900 MPa), which increases even to 2000 MPa (2 GPa). The increase…

    Milling – basics, division, definitions

    By referring to the literature, we can search for a lot of information about milling as a machining method. This article addresses contemporary aspects of this type of machining. In addition to machining with conventional parameters (conventional and CNC machines) I referred to high-speed machining and machining of difficult-to-cut materials. Currently, milling works as an…

Shaft technology – technological process – operation 20

Shaft technology also means machining holes, mainly axial but also lateral holes. In the case of this operation 20 a short blind hole is made. Often, the axial hole is long, i.e. its length is significantly larger than its diameter. It is assumed that the holes whose length to diameter ratio is greater by 8…

    Shaft technology – technological process – operation 10 5/5 (1)

    Operation 10 as part of each technological process is so-called first operation. The convention of numbering every 10 in the classic technological documentation made it possible to introduce another operation in a relatively easy way. There is no need for a deeper modification of the technological documentation, including the renumbering of all instruction cards, a…

    Turning – selection of machining parameters 5/5 (1)

    Machining parameters, including turning parameters (fig. 1), are a challenge for every technologist. The technological cutting parameters in the turning process include: cutting speed vc [m/min] (1) – D – diameter of the workpiece; n – rotational speed of the workpiece (main drive)    (1) main drive speed n [obr/min]; independent minute machining feed rate f [mm/min]…

    Shaft technology – technological process

    The shaft technology is a very popular subject in the process of technological education. There is an independent class of shafts as a class of parts in the technological context. Parts of this class are very commonly used components. The rollers (shafts) are among the simplest machining objects. The framework technological processes of the parts of…

    Workpiece as a casting in series production

    The blank (workpiece) in the form of a cast is economically justified in the case of series production (from 5,000 pieces). This article presents the basics of casting design in the context of further technological operations using mainly machining. The design of gray cast iron castings in sand molded by machine or by hand is…
