The machining processes are widely used in the industrial environment and aim to change the dimensions of a piece. At present, any improvements made to the machine, material, tool or process can lead to a reduction in manufacturing cost. The surface finish of each manufactured piece must be adequate according to the function that it will exert, thus, the surface roughness is of high importance when the requirements of the project grow. This work aims to analyze and model the surface roughness of ABNT 1045 steel under different metallurgical conditions. For the accomplishment of the experiments the steel was machined with tools of hard metal class P with covering. A factorial design 22 was used in the development of the experiments. As influencing variables, the feed, and nose radius of the tool were analyzed; the response variables were the surface roughness parameters Ra and RT. A commercial software was used for the development of mathematical models through the design of experime...

Measurement systems receive a continuous increase in its implementation and research in control systems area. These systems are responsible mostly for the acquisition, supervision and data control, resulting from the automation action in industrial processes. Microcontrolled systems are extremely importance, therefore optimize processes in various industrial areas daily, may have several other applicability due to small size and versatility. This work aims to present the study, design and development of a non-contact measurement system applied to a conveyor, for inspection of workpiece diameter transported continuously, using automated measurement techniques in manufacturing processes. The microcontroller PIC 18F4520 is used to actuate the system developed, responsible for the acquisition, processing, and display the results in the measurement, as well as being responsible for the capture of pulses emitted by encoder, at the time that occurs the interruption of the light beam, that ...
