When we think about technological innovation, our imagination usually conjures up images of sleek devices, touchscreens, or sophisticated software. Rarely do we consider what is happening “inside” – the tiny metal components that may measure no more than a few millimeters, yet determine whether a device works at all. It is precisely there, in the world of micron-level tolerances, that a quiet industrial revolution is taking place – one that is rarely discussed, even though it affects almost every one of us. A world that runs on millimeters Consider an…

Physics of Laser Beam Interaction with Metal in Thermal Cutting
Laser cutting of metals is one of the most advanced thermal processing methods used in modern industry. It combines optical, thermodynamic, hydrodynamic, and metallurgical phenomena occurring over very short timescales and at a microscopic scale. Understanding the physics of the process enables optimization of technological parameters, improvement of edge quality, and increased production efficiency and stability. 1. Laser Beam Interaction with the Metal Surface Absorption and Reflection of Radiation When a laser beam strikes a metal surface, part of the energy is reflected and part is absorbed by the material….
Read MoreMachining in Space – How CNC Machines Are Entering the Vacuum
Until recently, the idea of a machine tool operating in zero gravity seemed like pure science fiction. Today, however, it is becoming reality—advanced machining is making its way into space. In microgravity conditions, the first devices are being tested to manufacture mechanical parts directly in orbit. This is a technological breakthrough that could change the way crewed missions are conducted and, in the future, enable the construction of space infrastructure on distant planets. Why machining in space? Transporting every gram of cargo into orbit costs thousands of dollars. In emergency…
