摘要

众所周知,塑料加工和注塑行业的未来成型零件包含各种几何形状,在某些情况下,自由表面。为了生产这些形状,需要CAM系统的知识,使程序员能够选择必要的铣削策略,以实现最佳的质量和尺寸精度。然而,同样有必要理解和欣赏每种策略的效果,以及哪种策略最适合给定类型的表面。通过对加工表面形貌的评价,对精加工策略进行了比较。材料为AlCu4Mg铝合金,生产工艺选择Constant-Z和螺旋策略-圆型精加工策略。根据刀具与加工表面接触的不同高度,对所生产零件的表面形貌分析进行了评估和比较,这表明了刀具路径的变化,因此也表明了加工质量的变化。表面形貌结果表明,恒定Z策略更适合于生产异形表面,该策略在零件的整个高度上实现了均匀的刀具轨迹。

COMPARISON OF FINISHING MILLING STRATEGIES USING TOPOGRAPHY OF THE MACHINED SURFACE
The plastics processing and injection molding industry is known for the fact that the future molded part contains a variety of geometric shapes and, in some cases, free surfaces. To produce these shapes, knowledge of CAM systems is required to enable the programmer to select the necessary milling strategies designed to achieve the best possible quality and dimensional accuracy. However, it is equally necessary to understand and appreciate the effect of each strategy and which strategy is best suited for a given type of surface. The paper compares finishing milling strategies by evaluating the topography of the machined surface. The material was AlCu4Mg aluminium alloy, where Constant-Z and Spiral strategy – circle-type finishing strategies were selected for the production process. Surface topography analysis was evaluated and compared at three different heights of the produced part with respect to the tool contact with the machined surface, which showed a variation in toolpaths and therefore also in the quality of machining. The surface topography results demonstrated the Constant Z strategy to be the more suitable strategy for producing the shaped surface, which achieved uniform toolpaths over the whole height of the part.
