“…To control the forces that might deflect and deform parts causing defects, studies using finite element analysis and tool orientation optimization have been performed with favorable results [6]. In addition to reducing defects, research is also being undertaken to find more efficient tool path methodologies by determining the ideal tool path layers and flow line arraignment in order to reduce machining waste [7].…”

The implementation and effective utilization of advanced computer controlled machines and processes depends on a concerted effort by industry, machine and software vendors, and educators. Specialized and multipurpose machines such as 5-axis mills, turn-mill, and Swiss style lathes are becoming more popular and affordable. Furthermore, their controllers are becoming more versatile and integrated with sensors, probing capabilities, data collection and enterprise level software. Although trade schools do a good job at training operators and CAD/CAM technicians, there is a growing need for mechanical, manufacturing, and aerospace engineering graduates to have experience and a working knowledge of all aspects of component design, process planning, CNC programming, and process improvement so that companies realize a competitive edge from their investments. This is especially true in the aerospace industry, where factors such as part geometry complexity, difficult to machine materials, single setup fixture design, computer simulations, and reduced cycle times through optimization determine the difference between potential and realized gains in capability and efficiency. In this paper, the authors present a set of course modules that address some of the challenges mentioned above and propose a low-cost platform (hardware/software/tutorials) for other educators to get started. As Industry 4.0, the IIoT, Human Machine Interfaces (HMI's), and Machine Control Units (MCU's) become more sophisticated, the need for skilled personnel and good pedagogical tools will grow as well. Finally, the authors developed some tools to evaluate the effectiveness of the modules and gather feedback from students for future improvements.

Impellers are the most crucial components of pumps, as they directly determine the velocity profile of the fluid flowing through the pump and its efficiency. Given that the impellers have a complex geometry, they pose an important challenge to the manufacturer in order to construct them with the best possible dimensional accuracy and surface quality, and also achieve short machining times. In the present paper, the machining operations for the manufacture of a radial impeller were designed and implemented for the case of a single-entry semi-closed radial flow impeller. At first, the best milling strategies, optimum cutting conditions, and appropriate cutting tools were selected for each of the three machining phases, namely, roughing, semi-finishing, and finishing. Then, an experimental investigation was conducted, especially for the optimum process conditions during finishing of impeller blades, using Taguchi L16 orthogonal array. After the analysis of surface roughness was conducted for the 16 experiments, it was found that the most important parameters were spindle speed and feed. Furthermore, the optimum settings were determined as the maximum spindle speed and the lowest feed per tooth value and a regression model correlating process parameters with surface roughness was established with a high degree of accuracy.
