Laser pulse duration is one of the important parameters that is able to dramatically change ablation efficiency. Shorter laser pulse duration leads to deeper transport of absorbed energy in subsurface material layers. Ultra-fast and non-equilibrium processes are able to remarkably affect res...

The demographic evolution of the population in Europe indicates a trend, which predicts that the number of people over the age of 60 will increase over the next the world will increase by about 2 million per year in the coming decades. This forecast points to a ...

Perforation of lithium-ion battery electrodes has recently become an increasing interest in science and industry. Perforated electrodes have shown improved electrochemical properties compared to conventional, nonperforated electrodes. It has been demonstrated that through perforation, the fast-charging capability&#x...

In today’s unmanned productions systems, it is very important that the manufacturing processes are carried out efficiently and smoothly. Therefore, controlling chip formation becomes an essential issue to be dealt with. It can be said that the material removal from a workpiece using...

The aim of this paper is to present the possibilities of verifying the assumption of a normal distribution of data for further statistical processing, without the need to study an inexhaustible number of methods and hypotheses about statistical data processing. The main idea is...

The current world of industrial production can be defined as a period of growth and significant changes from traditional technologies to new solutions and revolutionary changes. One of these trends is the introduction of collaborative robots into production. The changes associated with ...

Coordinate measuring machines (CMMs) have been a major advance in the field of engineering measurement in recent decades. They were designed to measure complex shaped parts in the automotive and aerospace industries. The rapid development of CMMs is based on the need for increasing...

Grinding is one of the basic finishing operations which can be used for parts made from different materials where high quality and surface accuracy is required. One of these materials is maraging steel 1.2709, which is used for the test samples for tensile testing. In thi...

The paper deals with the very topical issue of evaluating the critical parameter of surface integrity. Nowadays, surface integrity measurement, especially the roughness of the surface, is extremely effective, because top production industries such as the aerospace industry or the automotive ...

Metal additive manufacturing provides an efficient way of processing metallic cellular structures. This relatively novel way of production is based on a powder bed which is melted using a powerful laser. Despite the advantages of this production technology, differences in geometry are o...

Lattice structures are one way to reduce the weight of a component while respecting its strength requirements. These structures are based on cubic cells, therefore, they are not fully applicable to rotating parts which should be lightweight. This article particularly addresses this issu...

Topological optimization is the process of reducing part weight while respecting strength requirements. This paper focuses on its possible positive consequences for the machining process. The main aim is to carry out a survey to obtain knowledge that will be applied during the topo...

This paper deals with 3D printing of metal parts. There are many principles of 3D printing, for example, DMLS, SLS, CLADDING, etc. This paper is limited to 3D printing using DMLS (Direct Metal Laser Sintering). 3D printing using DMLS can create complex geometries that cannot&#...

The aim of this paper is to evaluate and compare the corrosion resistance of Hastelloy C-276 coating with Stellite 6 and Cr3C2%-25% NiCr coatings. The coatings were deposited usingHP/HVOF(High Pressure/High Velocity Oxygen Fuel) thermal spraying technology. The corrosion test was conduc...

Machinability is a technological characteristic expressing the aggregate influence of the physical, mechanical and chemical properties of the machined material on the course and on the economic or respectively, qualitative results of the cutting process. It can be evaluated as a qualitative,...

In recent years, the 3D printing attracted an extraordinary interest thanks to its ability to create complex shapes and structures virtually unattainable using classical production processes. Additive technologies have succeeded in penetrating into a number of industry branches, which use them&#x...
