Laser texturing – GF Machining Solutions Laser P

Laser texturing is a laser beam forming technique for imparting specific properties to the surface layer of an workpiece. In the machine industry, laser technology is more associated with cutting, bonding and marking than with precise surface shaping. Illustrations 1 and 2 show examples of the use of laser texturing. As shown in Figure 2,…

    Shaft technology – technological process – operation 30

    Operation 30 is the penultimate operation of shaping the workpiece. The general technological process of the rollers indicates that the shafts technology provides for the machining of splineways before finishing. Looking at the basic general technological process of a stepped shaft without heat treatment, the splineways (on the external surface) are made after shaping. If,…

    Shaft technology – technological process – operation 10 5/5 (2)

    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 – 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

    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…
