“…Thus, the machined surface temperature is an important indicator of the cutting performance. There existed several experimental approaches in the literature to measure the process temperature in turning of hard-to-machine materials, including radiation thermometry [29], tool-workpiece thermocouples [30], and embedded thermocouples [31].…”

Titanium alloys have been widely used as an aerospace material owing to their excellent mechanical properties. However, ordinary tools can suffer from severe chip adhesion and surface abrasion when turning titanium alloys. To address these problems, micro-textured cutting tools have become a topic of significant research. Here, to improve the preparation process of textured tools, a novel tool prepared by an integrated molding process was proposed. The performance of this novel textured tool in terms of turning Ti-6Al-4V was investigated under dry conditions and minimal quantities of lubricant (MQL). Textured surfaces with four types of patterns and dimensions were used in the turning experiment to draw a comparison with traditional cutting tools. The results showed that the textured surface exhibited a uniform and smooth appearance with no obvious defects, indicating that the integrity of the textured surface was maintained. The combination of a micro-textured surface and the MQL method decreased the process temperature and cutting force. The narrower parallel type of textured tool exhibited the best performance. The process temperature reduced to 124 ℃ for the narrower parallel textured tool under MQL, decreasing by ~ 14.5% compared with the traditional tool; the lowest main cutting force and feed force were obtained for the narrower parallel textured tool, approximately 212 N and 171 N, respectively. Significant improvements in chip adhesion and tool wear were observed for the textured tool. Application of textured surface and MQL method are both decreased the adhesive scale layer area on the rake face of tools compared with ordinary tools.

“…Bono and Ni [20] and Fleischer et al [19] presented a mathematical model describing heat input as a function of the cutting parameters and tool geometry. Battaglia et al [21] used an inverse analytical approach to achieve this aim. They made stationary and linearity assumptions to break down the original three-dimensional problem into a bidimensional problem.…”

“…Basically, there are two main techniques to measure workpiece temperature: thermocouples [3,10,11,15,[17][18][19][20][21][22] and infrared methods [13,26,27]. Thermocouples are cheap and easy to handle, and by placing them in the workpiece, internal temperatures can be measured.…”

One of the current trends in machining is the reduction or elimination of the use of cutting fluids to reduce economic and ecological costs. As a consequence, heating of the workpieces is increased, leading to greater thermal distortion. This distortion can be predicted using the finite-element method (FEM), provided heat input to the workpiece for the machining operation is known. The aim of this research is to determine the quantity and ratio of heat generated in drilling operations and to quantify the heat transferred to the workpiece based on cutting speed and feed rate. Thus, a detailed study of workpiece heating during the drilling process with minimum quantity of lubricant was conducted, and a combination of experimental and numerical data was used to obtain these parameters. The experiments were carried out on aluminium (Al2017) samples. Drilling torque and temperature of the workpiece were measured. The cutting procedure involved drilling a Ø10 9 15 mm blind hole using uncoated cemented carbide tools. Temperature was measured by infrared methods, and cutting torque was obtained using a piezoelectric dynamometer. The FEM model was developed using the general-purpose software ABAQUS/ StandardÓ v6.5 and the inverse simulation technique was used to calculate heat input to the workpiece for each machining condition. As a general conclusion, an increase in cutting speed and feed rate leads to a decrease in heat input and temperature in the workpiece and thus, thermal distortion of the part.

“…In addition, local data measurements enables to enhance/validate numerical models that could better predict the thermomechanical load at local scale [9]. Numerical simulation results are mostly compared with the experimental ones at macroscopic level [10][11][12][13] through: i) force components measurement, ii) chip morphology and microstructure analysis and iii) temperature measurement at the tool tip [14][15][16][17]. These quantities remain global quantities and limit the understanding of local phenomena such as strain localization [18][19][20].…”

In-situ visualization of the material flow during orthogonal cutting is achieved using new high-speed optical system. Difficulties arise from the submillimetric size of the cutting zone. Therefore, a dedicated optical system was designed allowing for local scale analysis of chip formation. The Digital Image Correlation (DIC) technique is applied on recorded images from the cutting zone to measure the kinematic fields. Then, the effect of the cutting conditions on chip formation is presented with local scale analysis.
