Physics of Laser Beam Interaction with Metal in Thermal Cutting

December 22, 2025February 22, 2026

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….

Machining in Space – How CNC Machines Are Entering the Vacuum

June 23, 2025July 23, 2025

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…

CNC Turning – Modern Machining Technology

May 27, 2025June 27, 2025

What is CNC Turning? CNC Turning (Computer Numerical Control) is an advanced machining method that uses computer-controlled lathes to precisely shape materials. CNC turning technology revolutionizes industrial production, offering unparalleled accuracy, repeatability, and efficiency in manufacturing components with complex geometries. In the CNC turning process, the workpiece material is rotated around its own axis while the cutting tool moves in a manner controlled by a computer program. This method allows for the production of cylindrical, conical, and more complex-shaped elements while maintaining very high dimensional precision. History and Development of…
