    Cast as a blank – a step by step design

    Academic experience led to a return to the topic of developing a blank design as a casting. The selection of the casting mold division plane and the orientation of the casting, determination of the grade of allowance and accuracy class as well as the selection of foundry slopes are the main tasks of developing a…

    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 5/5 (2)

    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…

    Hole machining – drilling and reaming

    Machining holes in the sleeve and disc class parts plays an important role. When we pay attention to the general technological processes of these parts, in the case of classic technological processes, the general technological process of the sleeve class parts with hole-based is used. Selected problems of hole machining are presented below. Information about…

    Determining the machining time – main time

    The main time (tg – main machine time or main manual time) is a component of the standard of technological times. Its definition is one of the key components of the production process schedule. The more efficiently determine the main time, the more accurate estimates of production costs. Scheduling is the basis of any process,…

    Construction drawing and technology. How to read? 5/5 (1)

    During the design classes I noticed that the analysis of the construction drawing in terms of technology is a challenge. I consider this skill to be the key from the point of view of the technological preparation of production. The constructional drawing enables identification of functional and free surfaces. Contemporary design principles, including roughness are…

    Hadfield steel, prison steel, milling

    Hadfield steel is also known as prison steel, which results from one of its applications. Hadfield steel (Table 1) is widely known for its high abrasion resistance and hardenability while maintaining good plastic properties. High manganese steel (manganese), is used in the production of parts for machinery and equipment which requires very high resistance to…

  • 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 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…
