Requirements for flexible manufacturing have been increasing in the last years. In order to insure effective operation of expansive manufacturing equipment, which has to run automatically and unattended, tool monitoring is important. Therefore, the essential problem to be overcome to achieve the full potential of unmanned machining is the development of effective and reliably sensors systems to monitoring...
The paper presents the comparison of measured and simulated values of cutting force component during milling of a hot-work tool steel (applied for dies and moulds). Workpiece was made in the form of plate, screwed to the piezo-electric dynamometer. The cutting mill with solid carbide insert was used during tests. The results of experiments and calculations were compared.
This article presents the results of the identification of cutting forces for end milling using two mechanical models: linear and non-linear. In these models material factors were estimated on the basis of plots of cutting forces measured with a dynamometer. This paper presents factors determined in the domain of frequency and time. We also compare the adequacy of both models, and analyze forces and...
The article deals with the mathematical model of the primary contact of a milling tool in face milling. When designing the mathematical model, there were taken into consideration positive and negative geometry of the cutting wedge with different angle of taking instrument. Mathematical model is the input for experimental verification of the primary contact of milling tool and is aimed at improving...
The paper presents example of hard turning application, comparison with grinding technology and results of hard turning researches on cold work tool steel with cubic boron nitride tools. The influence of cutting conditions and material hardness on cutting forces and surface roughness are presented.
This article presents the state of knowledge on cutting forces during the milling of light alloys. Research results presented in the paper concern cutting forces and their amplitudes depending on the technological parameters (vc, fz, ap) with the use of two carbide milling cutters having a different cutting edge geometry (γ=5º and γ=30º). Research and analysis of cutting forces appear to be a significant...
The paper investigates the influence of cutting parameters (vc, f, m) on the main cutting force Fc and the feed force Ff during finish plunge hard turning of hardened 18CrMo4 steel with the use of Cubical Boron Nitride (CBN) inserts. The experimental research was conducted according to the Taguchi methodology. On the basis of the research results obtained, optimal values of cutting parameters were...
The finite element method has been extensively used for the simulation of manufacturing processes and especially machining. In this paper, finite element models of high speed machining are presented. More specifically, orthogonal and oblique cutting models are presented, where the geometrical and material properties of the cutting tool are investigated. Orthogonal models pertain to the simulation...
