This work investigates the milling of the surface of glass and carbon fiber-reinforced plastics using tools with a polycrystalline diamond insert. The milling process was conducted under three different conditions, namely without the use of a cooling liquid, with oil mist cooling, and with emulsion cooling. The milling process of composites was conducted with variable technological parameters. The variable milling parameters were feed per tooth and cutting speed. The novelty of this work is the use of recurrence methods based on the cutting force signal to analyze the milling of composites with three types of cooling. The primary aim of the study was to determine the effect of variable technological milling parameters on cutting force and to select recurrence quantifications that would be sensitive to the cooling method. It has been shown that recurrence quantifications such as determinism (DET), laminarity (LAM), averaged diagonal length (L), trapping time (TT), recurrence time of the second type (T), and entropy (ENTR) are sensitive to the cooling methods applied for the tested composite materials. The results have shown that it is possible to determine common ranges of changes in sensitive recurrence quantifications for the two tested variables parameters of milling: 0.63-0.94 (DET), 0.69-0.97 (LAM), 7.30-13.48 (L), 2.92-4.98 (TT), 17.01-38.25 (T), 2.02-3.16 (ENTR). The ANOVA analysis results have confirmed that the studied variables have a significant impact on the recurrence quantifications.
本研究使用带有聚晶金刚石刀片的刀具对玻璃和碳纤维增强塑料的表面进行铣削加工。铣削过程在三种不同条件下进行,即不使用冷却液、采用油雾冷却以及采用乳化液冷却。复合材料的铣削过程采用可变工艺参数进行。可变铣削参数为每齿进给量和切削速度。本研究的新颖之处在于使用基于切削力信号的递归方法来分析三种冷却方式下复合材料的铣削加工。该研究的主要目的是确定可变工艺铣削参数对切削力的影响,并选择对冷却方法敏感的递归量化指标。结果表明,诸如确定性(DET)、层流性(LAM)、平均对角线长度(L)、捕获时间(TT)、第二类递归时间(T)和熵(ENTR)等递归量化指标对所测试复合材料应用的冷却方法敏感。结果表明,对于铣削的两个测试可变参数,可以确定敏感递归量化指标的共同变化范围:0.63 - 0.94(DET)、0.69 - 0.97(LAM)、7.30 - 13.48(L)、2.92 - 4.98(TT)、17.01 - 38.25(T)、2.02 - 3.16(ENTR)。方差分析结果证实,所研究的变量对递归量化指标有显著影响。
