The use of self-moulding resins in industry makes it necessary to specify minimum values for the surface roughness parameters in order to avoid fluid leaks between the sealing planes. To meet this requirement, new tool classes, machining parameters, and methodologies are being used. Thus, this work applies a new methodology for plane milling, with the objective of increasing the tightness of the union with adhesive. The investigation was based on experimental planning techniques for the behaviour of the surface roughness in machining of AlSi₉Cu₃ alloy by frontal milling with refrigeration, carried out in a transmission union support, in high-speed cutting (HSC) machining centres. The evaluated parameters were the cutting speed (V_c) between 1250 m/min and 2250 m/min, and the feed per tooth (f_z) between 0.050 mm/tooth and 0.100 mm/tooth. Two cutters with ten polycrystalline diamond (PCD) inserts were used to mill the sealing surface, with one of the cutters having eight cutting inserts and two scratching inserts. The cutoff considered was 2.5 mm and the statistical technique of design of experiment (DOE) was used to evaluate the experimental results. The optimum roughness values, achieved with the cutter with scratching inserts, were a V_c of 1250 m/min and f_z of 0.05 mm/tooth.

用PCD工具加工的AlSi9Cu3（Fe）合金密封面的新铣削方法

在工业上使用自模制树脂使得必须指定表面粗糙度参数的最小值，以避免流体在密封平面之间泄漏。为了满足这一要求，正在使用新的刀具类别，加工参数和方法。因此，这项工作采用了一种新的平面铣削方法，目的是提高粘合剂结合的紧密度。这项研究基于实验计划技术，用于在高速切削（HSC）加工中心的变速箱联轴器支架中进行的通过正面铣削与制冷进行正面铣削加工AlSi ₉ Cu ₃合金时的表面粗糙度行为。评估参数为切削速度（V _c）介于1250 m / min和2250 m / min之间，每齿进给量（f _z）在0.050 mm /齿和0.100 mm /齿之间。使用具有十个多晶金刚石（PCD）刀片的两个刀具来铣削密封表面，其中一个刀具具有八个切削刀片和两个刮擦刀片。考虑的截止值为2.5 mm，并使用实验设计统计技术（DOE）评估实验结果。使用带有刮擦刀片的刀具可获得的最佳粗糙度值为V _c为1250 m / min，f _z为0.05 mm /齿。
