This dissertation presents a critical analysis regarding the use of some statistical methods applied to Quality in cases in which the collected data are not normally distributed. The general problem refers to the ...

The high degree of competitiveness demanded by market, the growing necessity of cost reduction and the constant search for better levels of quality have led the companies which produce dies and molds to optimize their ...

The study on the end milling of duplex stainless steel has been gaining prominence due to the challenges encountered in its low machinability. This occurs, therefore, these materials have low thermal conductivity, high ...

Prediction of tool life is important to ensure conformity of the product and to avoid damage to the product itself and to the machine. Surface roughness is an essential requirement for machined products. The main figure ...
