Experimental Design and Data collection of a finishing end milling operation of AISI 1045 steel

In this Data in Brief paper, a central composite experimental design was planned to collect the surface roughness of an end milling operation of AISI 1045 steel. The surface roughness values are supposed to suffer some kind of variation due to the action of several factors. The main objective here was to present a multivariate experimental design and data collection including control factors, noise factors, and two correlated responses, capable of achieving a reduced surface roughness with minimal variance. Lopes et al. (2016) [1], for example, explores the influence of noise factors on the process performance.

Pereira *1 *1 Academic Unit of Engineering of Itabira, Federal University of Itajubá, Brazil Abstract: The steel turning AISI 52100 has been gaining prominence in industry in recent years, as it allows machined parts to have better quality without the need for furthers processes. However, to ensure the final product quality, it is important that the turning for machining procedure is well planned and prepared, so that the cutting tools have their wear minimized in the process, while putting good productivity rates and zero occurrences of reworked parts. Thus, this article will study the quality of the machined surface in the turning process using interchangeable PCBN inserts. The aim is to identify the optimal combination of the input parameters that are cutting speed (Vc), feed (f) and machining depth (ap). The response measured is the roughness parameter Ra, under the influence of cutting fluid and tool wear.

Conception of an Electric Vehicle’s Robotic Platform Developed for Applications on CTS

Significant efforts have been made in last decades concerning intelligent systems, particularly in vehicular applications. Despite several solutions proposed for intelligent systems on the electrical vehicle platform, this work aims to demonstrate a novel approach for hardware and software interaction that allows the development of different modes of operation. Some capabilities include cooperative mode to fully autonomous mode and vice versa. Furthermore, this proposed embedded system provides the basis for higher module integration from different levels of application. The proposed work reports real experiments carried out in a local urban environment using a medium electric vehicle platform which includes an embedded system with some embedded sensors to illustrate the validity of such platform in the context of the Cybernetic Transportation System (CTS).
