摘要

在工业中,切削参数通常是由机器操作员选择的。机器操作员在生产高质量产品方面的经验和效率经常被用来决定参数的选择——低生产率是由于参数选择不当、加工效率低下和技术问题造成的。当今机械加工行业的关键问题集中在提高表面粗糙度的加工性能,同时尽量减少冷却剂的使用。该研究的目的是通过应用车削参数(如切削速度、进给速率和切削深度)来提高铝合金319工件(Al319)车削过程中喷嘴润滑系统的性能,以产生良好的表面粗糙度。采用响应面法(RSM)建立了本研究的实验方法,使用两轴向运动的数控车床和尺寸为1.0 mm的湿式冷却喷嘴进行实验。采用合成可溶性润滑剂、al2o3涂层硬质合金刀片和319铝合金作为切削刀具和工件材料。为了研究切削参数对表面粗糙度的影响,采用方差分析(ANOVA)方法,并采用响应面法实现最佳加工性能(RSM)。当比较干式和湿式冷却系统时,1.0 mm喷嘴的尺寸显示出合适的表面粗糙度。方差分析表明,在润滑技术实验中,影响表面粗糙度和加工性能的关键因素是1.0 mm喷嘴尺寸的利用率。结果表明,切削速度为270 m/min,切削深度为0.60 mm,进给速度为0.08 mm/min时的组合加工参数效果最佳,表面粗糙度Ra为0.94µm。采用冷却液尺寸1.0 mm的喷嘴技术,结合使用正确的加工参数,可以提高加工的切削量。在当前的研究中,1.0 mm喷嘴的新尺寸对于降低和提高加工业务的生产率以及减少对加工操作员经验和能力的依赖也很有价值。

Optimisation of variation coolant system techniques in machining aluminium alloy Al319
Cutting parameters are often chosen for machining by machine operators in the industry. The experience and efficiency of the machine operator in producing a quality product are frequently used to decide parameter selection—low productivity results from improper parameter selection, inefficient machining, and technological issues. Today's key issues in the machining industry are focusing on increasing machining performance on surface roughness while minimising coolant usage. The study's objective is to enhance the performance of the nozzle lubrication system during the turning operation of an aluminium alloy 319 workpieces (Al319) to generate good surface roughness by applying turning parameters such as cutting speed, feed rate, and the depth of cut. Response Surface Method (RSM) was used to create the experimental method for this investigation, carried out using a CNC lathe machine with two axial movements and a wet cooling nozzle with a size of 1.0 mm. Synthetic soluble lubricants, Al2O3-coated cemented carbide inserts, and Aluminium alloy 319 were utilised as cutting tools and workpiece materials. To study the influence of cutting parameters on surface roughness, the Analysis of Variance (ANOVA) approach was utilised while the response surface method was performed to achieve an optimum machining performance (RSM). When comparing dry and wet cooling systems, the size of 1.0 mm nozzle shows appropriate surface roughness. According to the ANOVA analysis, the key factor impacting the surface roughness as machining performance in lubrication technique experiments was the utilisation of 1.0 mm nozzle size. The findings of combination machining parameters at a cutting speed of 270 m/min and a cutting depth of 0.60 mm at a feed rate of 0.08 mm/min offered the best results, achieving a surface roughness, Ra of 0.94 µm. The use of coolant size nozzle 1.0 mm technology combined with the use of correct machining parameters can improve machining cuts. The novel size of 1.0 mm nozzle in this current research is also valuable for reducing and increasing productivity in the machining business, as well as reducing dependency on machining operators' experience and abilities.
