High-density polyethylene (HDPE) waste was successfully feedstock recycled, and the obtained chemicals were utilized for synthesis of plasticizers for polylactide (PLA). First, an effective route to r...
In this thesis, Artificial Neural Network (ANN) technique is used to model and simulate the Turning Process. Significant machining parameters (i.e. spindle speed, feed rate, and, depths of cut) and pr...
This study concerns the influence of turning and fermentation method on quality of raw cocoa. Fermentation trials were conducted in wooden box, plastic box and in heaps with or not turning. Cocoa fer...
The tuned mass damper(TMD) has been successfully applied to the vibration control in machining, while the most widely adopted tuning is equal peaks, which splits the magnitude of the frequency respons...
Due to the extensive use of highly automated machine tools in the industry, manufacturing requires reliable models for the prediction of output performance of machining processes. The prediction of su...
Purpose: of this paper is investigation of dynamic impacts on cutting edge during machining of locally hardened steel. Alteration of hardness on a single work piece is a source of impact on tool, whic...
Purpose: The paper presents a new hybrid multi-objective optimization technique, based on ant colony optimization algorithm (ACO), to optimize the machining parameters in turning processes. Design/me...
Purpose: Purpose of this research was to demonstrate tool wear by hard turning of martensitic stainless steel and this material is pronounced as difficult to machine material. The evaluation was done...
This paper presents machining parameters (turning process) optimization based on the use of artificial intelligence. To obtain greater efficiency and productivity of the machine tool, optimal cutting ...
Among the most important data produced and stored is product data. CAD data forms one of many contributors to product data. Although in most circumstances CAD data can be processed within the CIM env...
Surface roughness, an indicator of surface quality, is one of the most specified customer requirements in machining of parts. In this study, the experimental results corresponding to the effects of di...
分析了最小量润滑(MQL)切削中供液方位、供液距离等因素对切削液渗透能力的影响。在SB-CNC超精密数控机床上进行了MQL车削45号钢试验,通过对切削力、表面粗糙度和切屑形态的研究表明:喷嘴位于主后刀面且距刀尖20mm处供应较大量的切削液能达到良好的切削效果。
为了扩大全射流喷头压力适用范围,提出在喷管处加转折角增加喷头固有驱动力矩。转折角喷管的重要结构因素包括转折角角度和转折角力臂长度,理论分析推导出全射流喷头步进旋转时所受总驱动力矩和旋转角方程。对不同转折角角度或转折角力臂组成的7种不同喷管进行了试验,测量性能指标包括步进角度、步进频率、射程和均匀系数。结果表明:试验值与理论分析具有较好的一致性;工作压力影响射程、均匀系数和步进频率,对步进角度影响不...
In order to clarify availability of the so-called cross-flow model, some model experiments on longitudinal distribution of lateral force on a ship hull were carried out with the segmented model. Later...
