Special Issue Information

Dear Colleagues,

The machining of modern engineering materials presents an increasing array of challenges. One of the key objectives of mechanical processing is achieving high surface quality as well as precision in shape and dimensional accuracy. This is particularly critical in precision machining. Another essential aspect is efficiency. High-quality outcomes must be coupled with high production efficiency, directly influencing manufacturing costs. A third critical factor is tool durability. Tool wear affects the quality parameters of the manufactured components. Simultaneously, tool life impacts productivity and production costs. Therefore, continuous improvement of precision machining processes is of paramount importance.

This Special Issue is dedicated to advancements in precision machining, particularly focusing on modern and difficult-to-machine materials. The scope of this Special Issue encompasses all aspects related to enhancing machining processes, with an emphasis on optimizing cutting strategies and parameters, innovative tool materials and tool coatings, modifications in tool edge geometry, investigations into tool wear processes (both cutting and abrasive), the diagnostics and monitoring of machining processes, as well as the modeling and simulation of machining operations. Additionally, topics related to product quality, such as surface roughness, surface waviness, dimensional accuracy, and shape precision, are also explored.

The aim of this study is to investigate the impact of machining parameters on the deflection of a cutting tool (i.e., end mill) in the milling of a surface with a curvilinear profile. Test samples were made of aluminium alloy EN AW-7075 T651. Experiments were conducted using the Gocator 2530 laser line profile sensor for real-time measurement of dynamic tool displacement with an inspection speed up to 10 kHz at resolution ranging from 0.028 to 0.054 mm. Response surface methodology was used. Five main technological factors were analysed: cutting speed, feed per tooth (cutting parameters), amplitude, term (curvilinear profile parameters), and the number of flutes (end mill parameter). Obtained data were filtered and visualised as 3D plots. The results showed that cutting speed and amplitude had the greatest impact on tool deflection, while feed per tooth also played a significant role in process stability. In particular, the use of tools with a higher number of flutes led to a considerable reduction in tool deflection, confirming their positive effect on the stability of the machining process. These findings may serve as a basis for the optimisation of machining parameters by taking into account the dynamic deformation of cutting tools. Full article

Powder metallurgy tool steels, such as Vanadis 4 Extra (1.2210), are increasingly used in cold-work applications due to their superior hardness, wear resistance, and microstructural uniformity. Despite their growing popularity, there is limited data regarding their machinability, especially in milling processes. In this study, experimental milling tests were performed on Vanadis 4 Extra steel using AlCrN-coated carbide tools. A full factorial experimental design (34) was applied to investigate the effects of cutting speed, depth of cut, width of cut, and feed per tooth on cutting forces (Fx, Fy, Fz, Fc), surface roughness parameters (Ra, Rz), and tool wear. Cutting forces were measured using a Kistler dynamometer, and surface roughness was evaluated using a contact profilometer. Regression models were developed and statistically validated. The results indicate that depth of cut had the most significant influence on cutting force, while cutting speed had the greatest impact on surface roughness. Moderate correlation between cutting forces and roughness was observed, particularly under low-load conditions. SEM analysis revealed abrasive wear and chipping of the coating layer. The findings provide insights into the machinability of Vanadis 4 Extra and offer guidelines for optimizing milling parameters to enhance tool life and surface integrity. Full article
