“…This allowed to increase the tool durability. The problem with the tool wear is also mentioned in the study [5], in which the authors investigated the impact of the microstructure of cutters made of sintered carbides on the durability while milling the titanium-based Ti6Al4V alloy. It was proven that the tools having the ultra-fine-grained structure show the highest durability, especially crash wear resistance.…”

The pursuit to achieve a broadly defined optimisation of the manufacturing processes imposes the use of the increasingly innovative machining methods. The increase of the machining efficiency, assuring a high surface quality as well as precision of dimensions and shapes, necessitates the search for new methods to meet the demanding requirements, apart from the development of materials used for the working parts of tools, wear-resistant coatings or improvement of the cutting tool point geometry. One of the methods to improve forming by machining is the optimisation of the machining strategy during the manufacture of the components having complex shapes. The progress in this field is particularly noticeable along with development of the software for machining on multi-axis machines. This article presents the results of tests for the impact of machining strategy on passive force, cutting torque, material removal rate, topography of the obtained surface and the shape of chip resulting from the aluminium alloy milling. The tests were performed by comparison of the classic strategy available in the NXCAM system to the iMachining technology.

“…Beranoagirre et al discussed the machinability of gamma TiAl in EDM [18] and in drilling processes [19], where a mechanistic model was proposed for cutting force and torque prediction. Regarding soft titanium alloys, Kuczmaszewski et al [20] demonstrated that ultra-fine-grain SC milling cutters are the tools most resistant to chipping while leaving a good surface finish. Jozwik et al analyzed the tribological properties of Ti6Al4V [21] and the effects of the technological parameters of the selective laser melting (SLM) process on the morphological properties of the manufactured surfaces [22].…”

In the aerospace industry, a large number of holes need to be drilled to mechanically connect the components of aircraft engines. The working conditions for such components demand a good response of their mechanical properties at high temperatures. The new gamma TiAl are in the transition between the 2nd and 3rd generation, and several applications are proposed for that sector. Thus, NASA is proposing the use of the alloys in the Revolutionary Turbine Accelerator/Turbine-Based Combined Cycle (RTA/TBCC) Program for the next-generation launch vehicle, with gamma TiAl as a potential compressor and structural material. However, the information and datasets available regarding cutting performance in titanium aluminides are relatively scarce. So, a considerable part of the current research efforts in this field is dedicated to process optimization of cutting parameters and tool geometries. The present work is framed in the study of wear when machining holes in these difficult-to-cut alloys. In particular, the work presents the results from drilling tests on three types of gamma TiAl alloys, extruded MoCuSi, ingot MoCuSi, and TNB type, to define an optimal set of cutting parameters. Maintaining uniform, gradual wear is key to avoiding tool breakage and enabling good hole dimensional accuracy. So, this paper proposes a model based on ANOVA analysis to identify the relationships between cutting conditions and resulting wear and estimate tool life. The best cutting parameters were found at vc = 10–15 m/min and fn = 0.025 mm/rev.

“…Several types of wear exist: abrasive, chemical, adhesive, thermal, and mechanical. During stainless steel machining, the following wear phenomena occur very often: focused cutting edge wear, VB N ; cutting edge plastic deformation; and relatively soon accelerated chase widening [20][21][22][23].…”

The paper presents an assessment of the wear rate of turning tool blades during machining of steels applied in medical industry. The subjects of the research were stainless steels X20Cr13 (1.4021) and X8CrNiS18-9 (1.4305) used in production of surgical instruments. An experiment was carried out to assess the wear of multi-edge turning inserts with CVD coatings (Pafana CNMG 12 04 08 ZSZ and Sandvik CNMA 12 04 12-KR 3205), and an uncoated turning insert (Sandvik CNGA 12 04 08 T0102 WG 650). The wear was measured by the direct wear indicator VB C. On the basis of the results obtained for both X20Cr13 and X8CrNiS18-9, it was found that the Pafana CNMG 12 04 08 ZSZ turning insert had the best wear resistance during machining. The cutting path of Pafana CNMG 12 04 08 ZSZ was about 25 % longer than Sandvik CNMA 12 04 12-KR 3205 and about 300 % longer than Sandvik CNGA 12 04 08 T0102 WG 650. It was also found that each turning insert revealed a linear wear.
