Establish of efficient machining parameters has been a problem that has confronted manufacturing industries for nearly a century, and is still the subject of many studies. Optimum machining parameters are of great concern in manufacturing environments, where economy of machining operation plays a key role in competitiveness in the market. The aim of this paper is to present a method to integrate advanced technology issues into a simple and intuitive application for machining parameters calculus. The goal is the development of a program easy to use in industry for CAM engineers and machine operators, that optimize the cutting parameters (in ways that diminish the defects – vibrations, cutting tool wear, machine tools wear – and reduce the power consumption) depending on a number of parameters determined by experimental and analytical calculation. The program will integrate calculus algorithms based on experimental data and analytical results with a simple and friendly user interface.

The aim of our study was to identify if the AutoCAD application may be useful for evaluation during active movements of the body segments (lower limb), and how an orthopedic problem influence the normal pathway. The assement of range of motion is still problematic, especially when the body components is moving. Determining changes in the angles of motion dynamic is important in guiding the intervention plan. The evaluation methods are not enough objective all the time and many details could be not observed during different ADL (activities daily living). The AutoCAD (Auto Computer Aid Design) application was a valid instrument in order to realise the biomechanical analyse in case of knee arthritis. The analyze of moving components is possible using video frames and AutoCAD processing.
