Temperature measurement of cutting tool and machined surface layer in milling of CFRP

Cutting Forces in Milling of Carbon Fibre Reinforced Plastics

“…Yashiro et al [19] confirmed that the measurement of the cutting temperature is important when dealing with CFRP: temperatures higher than the glass-transition temperature of the matrix resin are not favourable as they damage the laminate. In Liu et al [20] a heat transfer model is developed to investigate the temperature distribution of CFRP workpiece in helical milling process.…”

Drill-exit temperature characteristics in drilling of UD and MD CFRP composites based on infrared thermography

“…15, have been studied to further elucidate the damage mechanisms within the large angle region of UD and MD [24][25][26][27][28][29][30][31][32][33][34][35][36][37] CFRPs. Fig.…”

“…Contact measurement methods commonly include the use of thermocouples, optical fiber sensors, etc. [18,19,31], whereas infrared thermography [32,33] has been explored for non-contact measurement of temperatures with the infrared camera. In the drilling of CFRP, researchers have employed embedded thermal sensors on the flank faces of drills to monitor the temperature with varying processing parameters [3,6,34,35].…”

“…In comparison, infrared thermography is capable of acquiring complete temperature data within a large detection area, which enables offline data processing/analysis [19]. The reliability of such technology has been verified in several studies with simultaneous thermocouple measurements during the CFRP machining processes [31,36,37].…”

Measurement and Analysis of Cutting Force, Temperature and Cutting-induced Top-layer Damage in Edge Trimming of CFRPs

“…It suggests that reducing the single cutting thickness and controlling the cutting temperature in the reasonable range are the effective approach to improve machining quality. 基于 Lekhnitskii 的各向异性弹性理论以及 Puck 失效 准则，计算分析了刀齿旋转瞬间的面下损伤深度。 陈燕等 [10] 基于 Hintze 模型，进一步分析了每齿切削 长度对毛刺产生的影响。上述理论模型都是从力学 角度，对加工过程进行了准静态分析，结果表明， 切削力是影响 CFRP 复合材料加工损伤产生的主要 因素之一。 在仿真研究方面，SOLDANI 等 [11][12] 采用宏观 等效均质建模方法同时考虑材料的各向异性，分析 了面下损伤深度、切削力随着纤维方向、刀具几何 以及切深的变化规律。RAO 等 [13][14] 采用细观多相建 模方法，建立了包含纤维、树脂及界面的细观模型， 利用该仿真模型，分析发现切削过程中纤维失效以 压溃和弯曲断裂为主。殷俊伟等 [15] 首次建立了可以 模拟复合材料连续切削过程的二维宏观仿真模型， 分析了直角切削不同纤维方向 CFRP 单向板时的面 下损伤深度变化规律。然而，上述仿真模型均未考 虑切削热对加工过程的影响， 造成模型的普适性差。 通过试验， YASHIRO 等 [16] 系统地分析了 CFRP 复合材料铣削温度随铣削参数的变化规律，结果表 明当铣削速度超过 300 m/min 以后，最高铣削温度 出现了饱和现象，即随着铣削速度的继续增加， 最高铣削温度的增速显著放缓。BRINKSMEIER 等 [17][18] 发现纤维的弯曲变形程度与加工过程中的热 影响区深度有关。 PECAT 等 [19] …”
