Ferramenta computacional para acionamento de motores de passo aplicados ao projeto de equipamentos CNC

Abstract

The high competitiveness between companies, the projects complexity, the machinery modernization, the production flexibility and the costs reduction, lead small and medium companies to aim new diversification of equipments and products to maintain themselves in a worldwide market. One way of seeking a better mechanic production concerning these aspects is using the equipments of the Computerized Numeric Command (CNC). This paper has the objective of creating a computerized tool (a software) that works as a Computerized Numeric Command unit. The system has the function of controlling the communication with the machine devices, and it also works to make possible the creation or usage of a text file with a CNC programming, to interpret, analyze, simulate and execute the information of a preprogrammed sequence of operations (CNC programming). The implementation of the control functions, of the equipment operation resources, of the software CNC simulation on a graphic screen and of the techniques of linear and circle interpolation showed the viability of the personal computers (PCs) application as a command unit developing the CNC machines with stepping motor starting.
