Development of a Tool for Programming the Machining Instructions in a CAM Environment
The objective of this paper is the develeppement a tool for programming the machining instructions in a CAM environment. To help the NC programming of all addresses, it was developed a module contributing to the adaptation of CN addresses for different languages FANUC, FAGOR, NUM, SINUMERIK and EIA, turning and milling. This module serves several functions. The first function is to seek designation of preparatory functions after selecting the command "/ operation" and "G-code" and the auxiliary functions. The second function allows the identification of all NC addresses with writing syntax desired codes. The third function is to automate the calculation of various parameters of cutting. The fourth function is devoted to the simulation programs.
VIBRATION STUDY OF A CUTTING TOOL BY THE FINITE ELEMENT METHOD
The problem of vibration cutting tools for machining has an important influence on the state of surface and manufacturing tolerances. In this paper, we presented a model of the dynamic behavior of a cutting tool; the goal is to be determined by the finite element method hierarchical trigonometric frequencies own a tool from the kinetic energy and energy deformation. A programme has been developed in FOLTRAN 77 can generate automatically calculate the frequencies.
