13. Evaluation of cutting forces and prediction of chatter vibrations in milling
The prediction of chatter vibrations between the cutter and workpiece is important as a guidance to the machine tool user for an optimal selection of depth of cut and spindle rotation, resulting in maximum chip removal rate without this undesirable vibration. This can be done by some approaches. In this work, an analytical method is applied in which the time

14. Estudo e monitoramento do processo de fresamento frontal com fresas de insertos intercambiaveis
This work presents an experimental research about the tool lives of face milling carbide tools when machining AISI 1045 steel bars. Milling experiments were carried out using several different relative position between tool and workpiece, varying the cutting speed and feed velocity simultaneously in order to keep constant the feed per tooth. The cutting spee

15. Desenvolvimento e implementação do controle digital de posição de um eixo para uma maquina fresadora
The general airn of this work is to present the developrnent of a digital control in one axis of a milling machine. This thesis is devided into four parts: rnodelling of the milling machine, continuous controller design, discrete controller aproximation and experimentaIs results. The software created to perf orm the discrete controller was developed in C lan
