A number of approaches have been proposed to achieve separation of concerns. Although all these approaches form suitable candidates for separating cross-cutting concerns in a system, one approach can be more suitable for implementing certain types of concerns as compared to the others. This paper proposes a hybrid approach to separation of concerns. The approach is based on using the most suita...

Existing corn harvester cutting blades have problems associated with large cutting resistance, high energy consumption, and poor cut quality. Using bionics principles, a bionic blade was designed by extracting the cutting tooth profile curve of the B. horsfieldi palate. Using a double-blade cutting device testing system, a single stalk cutting performance contrast test for corn stalks obtained ...

Tool wear condition monitoring has the potential to play a critical role in ensuring the dimensional accuracy of the workpiece and prevention of damage to cutting equipment. It could also help in automating cutting processes. In this paper, the feed cutting force estimated with the aid of an inexpensive current sensor installed on the ac servomotor of a computerized numerical control turning ce...

In this work, a novel hybrid cutting method combining non-progressive cutting with progressive cutting is proposed, where progressive cutting is applied on the outer hull while non-progressive cutting is applied in the inner core. Therefore it keeps the visual reality while significantly increases the efficiency and stability for consequent soft-tissue simulation. In addition, we combined the n...

& This paper presents a methodology for practical estimation of cutting force and cutting power. Based on a previously proposed definition, the power spent in metal cutting is the summation of four components: the power spent on the plastic deformation of the layer being removed by both major and minor cutting edges, the power spent on the tool-chip interface, the power spent on the tool-workpi...

In this paper, we compare the strength of the semantic and syntactic version of the cutting planes proof system. First, we show that the lower bound technique of [22] applies also to semantic cutting planes: the proof system has feasible interpolation via monotone real circuits, which gives an exponential lower bound on lengths of semantic cutting planes refutations. Second, we show that semant...

To solve the problem of water pressure fluctuation caused by the traditional double-acting intensifier, the paper has designed abrasive water-jet cutting machine based on phased intensifier as well as open numerical control system. The structure of cutting machine as well as the hardware structure and working principle of phased intensifier are introduced. The phased intensifier employs a const...

This work deals with problems of tool axis inclination angles in ball-end milling. Tool axis inclination angle contributes to improvement of functional surface properties (surface integrity surface roughness, residual stress, micro hardness, etc.), decreasing cutting forces and improving production. By milling with ball-end milling tool, using standard way of cutting, when work piece and cuttin...

The drilling is well known as one of the most common hole making processes in the industry.Due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. In the current work, an onlinedimensional controlling system was developed for drilling process. Doing this, drilling processwas executed in different ...

This paper discusses cake-cutting protocols when the cake is a heterogeneous good, represented by an interval on the real line. We propose a new desirable property, the meta-envy-freeness of cake-cutting, which has not been formally considered before. Meta-envy-free means there is no envy on role assignments, that is, no party wants to exchange his/her role in the protocol with the one of any o...
