“…Based on the recorded values of the cutting force components (F f , F p , F c ) it was noticed, the largest growth is for the passive force component F p . In this situation there is a clear different distribution tendency of the cutting force components than for the classical difficult-to-cut material turning (for instance, titanium alloy turning), where the largest values of the cutting forces have been measured for the feed force F f [3][4][5][6][7][8][9]. The largest values of the passive force F p is probably caused by the large hardness of the work piece material (85.4 HRA) or by a special material structure (shaft made of WC and Co grains).…”

“…Environmental considerations during technological processes [1,2] and development of new tool materials [3][4][5][6] cause a rapid increase in the use and development of the machining technology of super hard/difficult-to-cut materials. These types of materials have hardness above 60 HRC (for instance: sintered carbides with different content of cobalt as a binder material) or materials based on titanium alloy [7][8][9][10][11][12][13].…”

“…PCD has a low resistance to fracture toughness. Therefore, in the case of the WC-Co turning by PCD tools a proper selection of the cutting data values is required in order to prevent a rapid wear of the tool edge (especially, avoid the critical tool wear) or a damage of the work piece surface [6][7][8][9][10][15][16]21].…”

The paper presents the results of the cutting forces research (F f , F p , F c ) when machining of sintered carbides WC-Co (25 % Co) with tools made of polycrystalline diamond PCD. Inserts with three different nose radii r ε were used during the study. Each cutting test was carried out on the distance 54 mm at the constant depth of cut 0.2 mm. The biggest increase of passive cutting force component F p was indicated. In addition, the mathematical models for cutting force value prediction as the cutting path increases are presented. The paper presents also the algorithm of optimization and control of the super hard materials turning process.

“…The position of the tool in relation to the machined surface (inclination angle) has a strong impact on the cutting forces [1][2][3]. In [4] is an influence of up and down-copying on tool wear and [5] on the surface roughness. Tian et al [6] studied effect of cutting force to wear mechanisms for down and up copying.…”

The article deals with the tool life of ball nose end mills and surface roughness of steel C45 depending on contouring and copy milling. The aim was to determine and compare the wear of ball nose end mill and surface roughness parameter for different types of ball end milling strategies, as well as to specify particular steps of the measurement process. For tool life test, DMG DMU 85 monoBLOCK 5-axis CNC milling machine was used. In the experiment, the cutting speeds, feed rates, axial and radial depth of cut were constant. The coated cemented carbide was used as tool material. The cutting tool wear was measured on Zoller Genius 3s and laser Blum Micro Compact NT . Surtronic 3+ (Taylor Hobson) was used for surface roughness measurement. The results show different achieved surface roughness parameter of machined material C45 and tool life of ball nose end mills depending on milling strategy.

“…Experimental study on the high speed machining of hardened steel was performed by Begic-Hajdarevic et al 12 The results indicated that the better surface quality could be achieved in high speed machining of examined steel but at the cost of rapid tool wear. The experimental studies were carried out by Durakbasa et al, 13 on the optimization of end milling parameters and the determination of the effects of edge profile for high surface quality of AISI H13steel using precise and fast measurements.…”

Milling of hardened steel components provides considerable benefits in terms of reduced manufacturing cost and time compared to traditional machining. Temperature variation in milling is an important factor affecting the wear of cutting tools. The poor selection of milling parameters may cause excessive tool wear and increased work surface roughness. Hence, there is a need to study the machinability aspects during milling of hardened steel components. In the present work, influence of cutting speed, feed rate and radial depth of cut on milling temperature, surface roughness and cutting force during milling of AISI D2 steel has been investigated using response surface methodology (RSM) based models. From the parametric analysis, it is revealed that temperature increases linearly, whereas surface roughness increases non-linearly with cutting speed. However, for higher values of feed rate, an increased cutting speed considerably reduces the cutting force for specified depth of cut range. The present work also reveals that the selection of best cutting conditions is useful at the CAPP stage in the milling process particularly with tight tolerances.
