Induction hardening technology is mainly used for processing parts where high hardness, although conventional treatment of tool steels is ordinarily used in industrial practice, engineers continue to seek new procedures to rid tool steels of objectionable primary sharp-edged chromium carbides, wh...

Low-strength substrates and anthropogenic soils are always an issue in civil engineering. Based on the soil layer types, several methods could be used to improve the basic/foundation layer however it would be difficult to make sure if the specified requirements are achieved. Nowada...

Good mechanical properties of steels, in which appropriate heat treatment can produce mixed hardening structures, make them candidates for a broad range of applications, namely in the automotive industry. TRIP steels (in which transformation-induced plasticity operates) with a carbon content of&#...

Induction hardening is mainly used for treating parts in which high hardness, wear-resistance, and ductile core are required, such as spur gears, wind turbine rings, and bearings. Innovative induction hardening processes are also developed for complex automotive components, such as camshafts ...

This paper deals with the innovative Quenching and partitioning (QP) heat treatment of low-alloyed chromium steel, and is especially focused on the higher temperatures of partitioning as well as longer holding times and its influence on mechanical properties of the material. As part...

The study focuses on microstructural evolution in a WC-Co powder mixture during Selective Laser Melting (SLM) and hot isostatic pressing (HIP) processing. This powder mixture contained a 13 plus/minus 0.6 % weight fraction of Co binder and WC particles of mean size of 3.0 ...

The article deals with the use of additive technologies (AM) to produce a fusible model for a casting. AM technologies SLA, FDM, or PolyJet have been used to create models of castings of musical instrument keys from various polymeric materials. The roughness profiles of the&#x...

The article is directly linked to the article called “Geometric Specification of Complex Spatially—Oriented and Compliant Components I”. Manufacturers of complicated and flexible machine parts, particularly in the automotive industry, are finding themselves in almost insoluble problems when designing ...

We are at the beginning of the fourth industrial revolution, which is already fundamentally influencing how goods are produced and distributed. Also, the rapid progress of the digitizing wave is exacerbated by the increasing availability of automated machines. Autonomous machines are no ...

The field of internal logistics is one of the critical areas of a company and has a great potential within the concept of Industry 4.0. The basic premise of smart production is to have a complete overview of all the logistics movements of products, i.e. from entry,&#...

The first part of the paper contains the description of Industry 4.0 concept. The different views on this concept and main principles are mentioned. One of these principles is named Smart Factory. The Smart Factory concept is briefly described afterwards. The second part of th...

The paper deals with a proposal of the methodology for the evaluation of optimization experiments performed on simulation models (discrete event simulation models and Bin Packing Problem) focused on various problems in the industrial engineering. We created the application evaluating simulation&#...

In-situ tensile testing of a 27CrNiMoV alloy which is used for steam turbine rotors was carried out using scanning electron microscope (SEM). Deformation and crack formation and propagation were examined with this test. Small (45 × 10 × 1.5 mm, with gauge length of 20 mm)...

Geocell soil reinforcement method is became one of the common improvement method used in different aspects of geotechnical engineering. The experimental investigation using physical modelling is somehow complicated and needs more financial support especially when using saturated or partially saturated...

Maraging steel is an iron-nickel steel alloy which achieves very good material properties like high toughness, hardness, good weldability, high strength and dimensional stability during heat treatment. In this work, maraging steel 18Ni300 was manufactured by selective laser melting. It is a&...

The paper deals with optimizing of the headstock of the lathe part of the heavy duty CNC machining centre for 70 ton workpieces using topology optimization. The aim was to find a solution that minimizes compliance and reduces weight of the housing of headstock by 5%. ...

According to Industry 4.0 the process of digitization in manufacturing companies has advanced to the virtualization phase. The final state should be a complete virtualization of the production plant. However, virtualization has a high demand for innovation. This article summarizes the findin...
