This article presents analysis of inverse dynamics of a serial manipulator in milling process. With the exception of positioning accuracy issue, machining by robots have more advantages than by conventional CNC milling machines, due to higher flexible kinematics (many links and degrees of freedom) and larger working space. Therefore, motion of the robot links is more complicated. Process forces and complicated motion involve to difficulties in solving dynamic problems of robots. This affects the robot control to match machining requirements.

Inventions in steam engines, cotton mills, and iron works converged in the eighteenth century to propel the First Industrial Revolution. Inventions in internal combustion engines, electrification, and steelmaking in the nineteenth century ushered in the Second Industrial Revolution. Today, twentieth-century inventions in digital technology are being conjoined with twenty-first-century innovations in software, materials and advanced manufacturing processes, robotics, and web-based services to inaugurate the Third Industrial Revolution.

An electric drive is the electromechanical system that converts electrical energy to mechanical motion. Being a part of automatic equipment, it acts together with the driven object, such as a machine tool, metallurgical, chemical, or flying apparatus, domestic or medical device. Electric drives area includes applications in computers and peripherals, motor starters, transportation (electric and hybrid electric vehicles, subway, etc.
