Tematy:: face milling
cutting forces
Opis:: Cutting forces during face milling are investigated intensively analytically and experimentally. Some of previous approaches to cutting forces determination consider only main (tangential) cutting force component, and according to this define cutting power. The experimental investigations were performed during face milling with a goal to determine models of cutting force versus cutter revolution. Different models were determined according to the cutter approach to the workpiece during cutting angle of revolution.

Opis:: Cutting forces during drilling and selected physical and mechanical properties of the finish coating based on epoxy resin. Paper presents selected tests of epoxy resin coating applied to American walnut wood (Juglans nigra L.). The aim of the study was to assess the machinability of wood flooded with resin during drilling. The axial forces and torque values were adopted for the machinability criteria. The idea of the research was the thesis questioning the possibility of processing epoxy resin coatings with the application of tools and parameters used during wood processing. In addition, the influence of UV light on the obtained coating was examined and abrasion tests were carried out. It was found the resin changes its colour under the influence of UV radiation, but the change is imperceptible to an average observer. Epoxy resin is characterized by low abrasion resistance compared to commonly used paint and varnish coatings. Although solid resin is characterized by high cutting resistance while drilling, the force values do not exceed the commonly cut wood-based materials.

W pracy przedstawiono wybrane badania powłoki z żywicy epoksydowej naniesionej na drewno orzecha amerykańskiego (Juglans nigra L.) Celem pracy była ocena skrawalności żywicy epoksydowej oraz drewna pokrytego żywicą epoksydową podczas wiercenia. Za kryterium skrawalności przyjęto wartości siły osiowej oraz momentu obrotowego. Genezą badań była teza stawiająca pod znakiem zapytania możliwość obróbki powłok z żywicy epoksydowej przy pomocy narzędzi i parametrów stosowanych podczas obróbki drewna. Ponadto zbadano wpływ światła UV na uzyskaną powłokę oraz przeprowadzono badania ścieralności. W wyniku badań stwierdzono, że pod wpływem promieniowania UV żywica zmienia swoją barwę, jednak zmiana jest niezauważalna dla przeciętnego obserwatora. Żywica epoksydowa charakteryzuje się niską odpornością na ścieranie w odniesieniu do powszechnie stosowanych powłok malarsko lakierniczych. Mimo iż lita żywica epoksydowa charakteryzuje się wysokimi wartościami siły osiowej i momentu obrotowego podczas wiercenia, jednak wartości sił nie wykraczają poza powszechnie skrawane materiały drewnopochodne.

Opis:: The paper presents a method for measuring and recording the forces involved in the coal cutting process. Moreover, a method for visualization of all forces involved in the cutting process was described. In the following part, the construction and principle of operation of a device for determination of forces involved in the cutting process (coal mining), referred to by the author as POU-BW/01-WAP, are presented. Resistance extensometry was used to measure the forces. This is the only device in the world that determines two of three force components that take part in the cutting process. For this purpose, two independent measuring blocks were used, which are strain gauges of force: cutting (Fs) and knife pressure (Fd). In order to register these forces, a real mining knife used in longwall shearer drums was applied – i.e. tangential-rotary. The equipment has the ATEX certificate allowing for operation in real conditions as a device intended for use in potentially explosive atmospheres – in accordance with the directive 94/9/EC. It has received many awards at world fairs for inventions and innovative solutions.

Opis:: Carbon fiber reinforced polymeric (CFRP) composite materials are widely used in aerospace, automobile and biomedical industries due to their high strength to weight ratio, corrosion resistance and durability. High speed machining (HSM) of CFRP material is needed to study the impact of cutting parameters on cutting forces and chip microstructure which offer vital inputs to the machinability and deformation characteristics of the material. In this work, the orthogonal machining of CFRP was conducted by varying the cutting parameters such as cutting speed and feed rate at high cutting speed/feed rate ranges up to 346 m/min/ 0.446 mm/rev. The impact of the cutting parameters on cutting forces (principal cutting, feed and thrust forces) and chip microstructure were analyzed. A significant impact on thrust forces and chip segmentation pattern was seen at higher feed rates and low cutting speeds.

Opis:: The present research employs the statistical tool of response surface methodology (RSM) to evaluate the machining characteristics of carbon nanotubes (CNTs) coated high-speed steel (HSS) tools. The methodology used for depositing carbon nanotubes was Plasma-Enhanced Chemical Vapor Deposition (PECVD). Cutting speed, thickness of cut, and feed rate were chosen as machining factors, and cutting forces, cutting tooltip temperature, tool wear, and surface roughness were included as machining responses. Three-level of cutting conditions were followed. The face-centered, Central Composite Design (CCD) was followed to conduct twenty number of experiments. The speed of cutting and rate of feed have been identified as the most influential variables over the responses considered, followed by the thickness of cut. The model reveals the optimized level of cutting parameters to achieve the required objectives. The confirmation experiments were also carried out to validate the acceptable degree of variations between the experimental results and the predicted one.

Opis:: The purpose of this article was to evaluate the significance of the influence of five- axis orientation parameters of a toroidal cutter axis and the geometrical parameters of the machined sculptured surface on the intersection of the cut layer in a 5-axis machining. An impact assessment was performed by simulating concave-convex and convex-concave surfaces using a discrete method of direct transformation in a CAD environment. It was shown that only the radius of curvature of the surface in the feed direction and the angle of the tool axis affected the change in the intersection of the cutting layer. Subsequently, experimental tests were conducted that aimed at determining the mathematical models of the influence of these important parameters on the components of the cutting force. The object of the experimental studies was a convex and concave surface of a turbine blade of Inconel 718 alloy. The R300-016B20L-08L Sandvik Coromant toroid cutter was used for the tests. Based on the results of the study it was found that the lead angle in the machining of the convex surface and concave turbine blade should be continuously varied with the change of radius of curvature in the direction of the machined surface profile.

Opis:: Band sawing is one of the most efficient methods for which in general it is known that uneven tool wear, chatter and cutting blade defects can affect cutting performance significantly. A data acquisition system was arranged on an industrial band saw machine in order to characterize the band sawing process based on measurements of forces. In this paper, the cutting force signals are analyzed in order to demonstrate important relations to workpiece and cutting blade properties. It is shown that cutting forces contain information about in homogeneity of a cut workpiece. Signals of cutting forces also reveal important properties of blade geometry that is related to uneven blade wear. Discontinuities such as blade welding are clearly evident in force signals and it is shown that unevenness of blade backing geometry can cause a significant variation in forces due to wedging between the workpiece and a blade support. An original method for blade shape extraction from force signals is presented in detail. Paper also reports on chatter phenomena observed at specific cutting conditions. Possible solutions to the addressed problems and phenomena are discussed in the conclusion.

Opis:: In modern production, milling is considered the widespread cutting process in the formatting field. It remains important to study this manufacturing process as it can be subject to some parasitic phenomena that can degrade surface roughness of the machined part, increase tool wear and reduce spindle life span. In fact, the best quality work piece is obtained with a suitable choice of parameters and cutting conditions. In another hand, the study of tool vibrations and the cutting force attitude is related to the study of bearings as they present an essential part in the spindle system. In this work, a modeling of a High Speed Milling (HSM) spindle supported by two pair of Active Magnetic Bearings (AMB) is presented. The spindle is modeled by Timoshenko beam finite elements where six degrees of freedom are taken into account. The rigid displacements are also introduced in the modeling. Gyroscopic and centrifugal terms are included in the general equation. The bearings reaction forces are modeled as linear functions of journal displacement and velocity in the bearing clearance. A cutting force model for peripheral milling is proposed to estimate the tool-tip dynamic responses as well as dynamic cutting forces which are also numerically investigated. The time history of response, orbit, FFT diagram at the tool-tip center and the bearings dynamic coefficients are plotted to analyze dynamic behavior of the spindle.
