“…The previously developed machine simulation [5] must be adjusted for modular machine tools. Looking at the current solution in more detail, the adjustments can be divided in the two main parts of virtual machine model and simulation of the CNC.…”

“…Other solutions might derive from one of these kinds and include additional functions of the other versions. Because the previously developed solution [5] used the real CNC SINUMERIK 840D from Siemens, now a rough comparison was drawn between the SINUMERIK 840D, the Virtual NC Controller Kernel (VNCK) and a simple NC program parser (Table 1). Comparing the degree of simulation and effort to setup the simulations for the first time, the results turn out as expected.…”

“…This paper describes a machine simulation which not only handles complex machines but also works for refitting machines or during the first planning phases, using the wide range of module based machine tools. This simulation combines a highly accurate hardware-in-the-loop machine simulation [5] with the methods of modular-based production. The adjustments of the simulation are not only needed for the virtual models but also have a high impact on the interface and the CNC used in this kind of simulation.…”

One of the most recognized trends in production today is the increasing demand of complex and personalized products. This leads to an increasing demand for machine tools. As a consequence machine tools are required to be adaptable and modifiable for different products or different conditions. To fulfill this precondition while keeping up or increasing productivity, the concept of modular systems is used nowadays to design and manufacture machine tools. However, during the first steps of planning new production processes neither the customer nor the manufacturer of a new machine tool knows the resulting effectiveness of the composed machine tool configuration. Currently assumptions on the effectiveness are made based on experience or comparative processes. This paper presents a method for a hardware-in-the-loop machine simulation, which can be used to optimize the design process of machine tools based on modular systems. This machine simulation should automatically adjusts the virtual model according to the current machine tool configuration, taking into account 3D geometry, kinematic structure and its performance characteristics, e.g. acceleration and velocity. The specific configuration of the machine not only affects the virtual model but also the necessary configuration of the real CNC, which also influences the hardware-in-the-loop coupling needed for the simulation. Using a machine simulation with the developed methods will increase the quality of estimations during the first planning phases, thus improving the decision making process. Additionally, the communication between the manufacturer and the customer will be optimized by applying this method for sales and distribution. This paper describes first steps to create such a machine simulation, by combining and adapting numerous methods.

Background: Training workers in machine tool operations is indispensable. Because training course at school with real machine tools is costly and dangerous, most researchers have concentrated on developing and adopting virtual reality (VR)-based applications. However, to improve students' learning performance levels, teaching design is imperative.Purpose: This study hopes to investigate the performance differences between sequence-(traditional) and context-based teaching designs along with a selfdeveloped VR computer numerical control (VRCNC) training environment. Method: Experimental design, sequence-and context-based teaching designs were developed for this study. Forty male senior students were recruited from the department of mechanical engineering at an industrial high school. Then, corresponding pretests, teaching activities and posttests were implemented based on the proposed teaching and experimental designs. Finally, experiment-, questionnaire-, and interview-based performance evaluations were utilized to conduct the final comparison and conclusion.Results: Averagely, the context-based teaching design exhibited superior results for mostly the learning performances. The survey results also revealed that the students obtain more satisfaction and self-confidence after the context-based teaching.Conclusions: According to the results, the context-based teaching design has obvious improvement on the performance of machine tool operation training. Three types of evaluation results provides a comprehensive support for the proposed context-based teaching design along with the VRCNC in machine tool education.
