The use of CAM system to create tool s trajectories in outline of simple geometry depends directly of knowledge and ability from user in how to maintain the information and make use of available riches from these systems. The parametric program requires a solid knowledge in CN programming and the results referring to CNC machine s performance are directly connect to the way of programming to obtain these results. The aim of this study was to develop a practice s analysis between parametric program and a CAM system in a specific CNC machine, based on acting time and speed of tool s progress to each programming method. The counting of time was accomplished through CNC controller, which shows the execution time of each program from its beginning until receiving or reading the stop command. The comparison between these programming methods created results that depend of the programming way, but who receive interference of controller s technologies recourses to put in action the CNC axis machine. With these testing, it was possible to demonstrate, by means of parametric programs, an increase of 65% in performance, when compared to other programming methods.
