“…Consequently, high accuracy leads to a reduced machining time as only few sweeps are needed to cover large portions of the surface [21]. Another research category closely related to our research deals with barrel tools [1,22,23]. Barrel tools are shown to fit well free-form surfaces, especially in concave regions where the principal curvatures of the tool match their counterparts of the surface.…”

“…In our implementation, a ruled surface is realized as a B-spline patch of bi-degree (1,3), that is linear along the rulings (sdirection) and cubical in the t-direction, see Fig. 10.…”

“…Manufacturing of free-form surfaces is a substantial part in automobile and aircraft industries. Components like turbine blades, rotors, or gears are smooth, yet curvature-varying objects and their efficient manufacturing introduces several challenging problems in geometric modeling and computing because the very complex shape of these objects prevents them to be manufactured using simple straight cutting tools [1].…”

“…To rapidly produce the copies or scale models of such physical prototypes, these models are first sampled using either contact or non-contact scanning devices, and then the gained data points are transformed to CAD representations on which the tool paths are subsequently generated for CNC milling [1]. At present, with the rapid development of 3D scanning devices, the dense and accurate cloud of point, which can represent more exactly the geometry of the physical parts than before, has been readily available for various industrial applications such as reverse engineering (RE), rapid prototyping (RP), and computer numerical control (CNC) milling [2,3]. However, the CAD representation for the cloud of point is still the bottleneck of the whole producing procedure though many works have been done for the solution of CAD model reconstruction.…”

This paper presents a gouge-free tool path generation method for direct ball-end cutter CNC milling of cloud of point. In this method, a base surface with simple geometry, which can approximately reflect the features and the changes of surface shape, is first constructed, and the guide curves with different patterns of the cutter motion are then planned on it. After the cloud of point is offset by a distance of the ball-end cutter radius, the guide curves are deformed onto the offset of cloud of point by point projection operation along the computed direction instead of the traditional z-axis direction, thereby forming the desired tool paths directly on the cloud of point. In projecting guide curves, the computation of the projecting direction and construction of the weight function are discussed in detail to eliminate the projection error as much as possible. The technique of adjusting the path points is also presented to eliminate the unfavorable undercuts and overcuts. Since the cloud of point is offset a distance of the cutter radius, the gouge between the cutter and the point set surface can be automatically avoided. Also, various patterns of the cutter motion can be conveniently planned on the simple base surface, such that the cloud of point can be milled along the generated tool paths with the most suitable topology. Finally, several examples are given to validate the proposed method.

“…Depending on the specific application, medium or finishing operations and on the engaged length of the cutter, these high-performance tools are divided into different groups (Figure 1). They are preferred due to smoother cutting forces [15,23,25], better surface finish [27] and reduced cutting times. To improve tool life and surface quality [17], key parameters for machinists are cutting forces and surface roughness [10].…”

Currently, there is a big gap between industry and the instructions provided by engineers at the University. Manufacturing companies need engineers with specific profiles and skills in machining. Teachers, who face both worlds, must play an active role in shortening the transition times of students. Recently, barrel‐end mills have been the focus of attention of toolmakers and manufacturers due to their excellent production times and surface accuracies. They are outstanding competitors to more traditional ball‐end mills in some applications. This study raises the challenge of translating the developed work for this kind of tool from the research domain into the classroom at the University. For this, a software tool proBARR© was developed and used for learning of the subject of manufacturing. This educational software is capable of predicting cutting forces and surface topography in milling with barrel‐end mills and was successfully introduced as part of the students' learning process. A software tool was created for the analysis and prediction of cutting forces and surface quality in milling processes with barrel‐end mills. This specific problem was addressed from past experience in research projects but was then adapted for academic use. The teachers believe that, if suitably presented to students, the tool provides an excellent opportunity to approach real problems in industry, thus boosting instructions for future engineers. In this way, a pragmatic methodology to computational thinking is presented that transforms traditional difficulties associated with process modeling into more comprehensive tasks, more oriented toward solving specific problems.
