Opis:: In traditional industries, manual grinding and polishing technologies are still used predominantly. However, these procedures have the following limitations: excessive processing time, labor consumption, and product quality not guaranteed. To address the aforementioned limitations, this study utilizes the good adaptability of a robotic arm to develop a tool-holding grinding and polishing system with force control mechanisms. Specifically, off-the-shelf handheld grinder is selected and attached to the robotic arm by considering the size, weight, and processing cost of the stainless steel parts. In addition, for contact machining, the robotic arm is equipped with a force/torque sensor to ensure that the system is active compliant. According to the experimental results, the developed system can reduce the surface roughness of 304 stainless steel to 0.47 µm for flat surface and 0.76 µm for circular surface. Moreover, the processing trajectory is programmed in the CAD/CAM software simulation environment, which can lead to good results in collision detection and arm posture establishment.

Opis:: The article presents comparative research on the effects of milling of concave corners of elements made of aluminum alloy 7075. The work focuses on the study of the impact of changes in technological parameters and types of machining on the obtained geometrical state of the machined samples. Correct milling of the corners requires selection of the appropriate feed rate and the proper engagement angle of the milling cutter. At the corners, tool engagement angle increases, which significantly hinders the execution of stable machining and adversely affects the geometric and qualitative characteristics of the surface in the corners. Study with application of various strategies and technological parameters of milling corners with variable opening angles were carried out. The main parameters of surface roughness of the machined elements were examined. When analyzing the results obtained, conclusions were formulated indicating the relationship between the change of selected technological parameters, with the assumed type of treatment, and the obtained quality parameters of the samples made.

Tematy:: lapping

Opis:: The finishing processes are an important perspective to be considered today to meet the goals like parallelism, tolerances, flatness and smooth surface of workpieces. These processes are high-precision abrasive processes. A leading importance in this perspective has the lapping process. It leads to a surface with low roughness and high precision. This paper reports the results of surface analysis of sealing elements made of oxide ceramic Al2O3. Because of elements, application as sealing parts in water valves, high surface quality and flatness is required. To meet those requirements grinding and lapping were execute. The first was realized by elements manufacturer, the second – during experiments. Research was carried out on a plate-lapping machine ABRALAP 380 with a grooved cast-iron lapping plate and three conditioning rings. As abrasive material boron carbide was use. Surface quality was investigated firstly after grinding and then, after lapping. A Hommeltester T8000-R60 profilometer with a resolution of 0.01 μm was used. The surface roughness parameters Ra and Rk were studied in the light of varying lapping parameters, like grains size, lapping pressure, velocity and time. According to literature, those are the most extensively used parameters for describing the surface roughness after finishing processes. Additionally the Abbot Firestone curves were analysed.

Opis:: The use of artificial neural networks for modelling and inference about surface parameters is a more and more often undertaken research topic. Based on the analysis of the ranges of suitability of surface topography parameters, a variety of different parameters can be observed to identify surfaces with different features and different conditions of use. The issues of surface topography analysis and determination of surface condition after abrasive machining are of fundamental importance. Currently, when assessing the surface intended for interaction with the other surface, it is possible to use many surface evaluation parameters. Assigning the machined surface to the appropriate assessment group, especially in automated quality control systems, requires a preliminary surface classification. In this article Hamming's network was used for the surface classification along with modification of Hamming distance.

Opis:: Analysis of the geometric features and determination of the condition of the surfaces machined during an abrasive process is of crucial importance for evaluation of their wear properties. Numerous parameters can be used for assessing topography of technical surfaces. Many of them contain information that is general or poorly correlated with the wear features. The group of parameters used for such purpose should include those that do not cause information redundancy and provide distinct information. Evaluation of the surface geometric structure after precision machining is a difficult process due to the limited scope of unevenness heights that fit within the range of a few micrometers to a few nanometers. In this paper the synthetic indexes of the evaluation of extra smooth surfaces were created, taking into consideration numerous elementary parameters. The value of the synthetic index was determined as the geometric average of the partial indexes which, when compared to the arithmetic average, is more dependent on the data believed to be disadvantageous.

Opis:: The article presents a review of research methods for the cutting process using the abrasive waterjet machining. The focus was on assessing the possibility of monitoring the cutting process based on the parameters available for direct or indirect measurement. An attempt was made to evaluate their influence on the machined surface after treatment with the abrasive cutting method. These parameters include, inter alia, vibrations of the cutting head, force effects on the head support structure and the material to be cut, dynamic properties of the machine support structure and high pressure pumps. As part of the own research, correlation was sought for the registered selected signal characteristics with the cutting parameters responsible for the process course and the parameters related to the obtained machined surface. For this purpose, a model of the deflection angle of the abrasive waterjet was proposed, which qualitatively determines the condition of the surface after cutting. The angle of inclination of the abrasive waterjet is determined on the basis of the registration of the feed force during the cutting process. The research on surface topography was extended by an attempt to determine the surface roughness by measuring vibrations and looking for correlation between the displacements of the cutter head tip and the measured roughness height profile. These tests also allowed the identification of selected frequencies that clearly result from the set parameters of the cutting process. The last stage of the research was to monitor the cutter head behaviour using a deformation sensor as another concept for recording the forces during the cutting process. Finally, the proposed methodology was characterized in the context of its usefulness in the on-line process monitoring and supervision system.

Opis:: High precise measurement techniques and surface structure analysis are required in advanced fields of interchangeable manufacturing and precision engineering. This study presents the characterization of the surface roughness of the machined milling cutters by experimental precision measurements and the image processing tool. The data obtained are compared to assess the surface characterization parameters and computational data in terms of precision, accuracy, sensitivity, repeatability and resolution. In the experimental measurement phase, the roughness measurements and surface topography characterization were performed in the nanotechnology laboratory using the stylus profilometry and digital microscopy. The computational phase was performed using an image processing toolbox with precise evaluation of the roughness for the machined metal surfaces of the end mill cutting tool. The surface parameter database is established exhibiting an advantage over the traditional method. This study reveals a comparison methodology of the end mill surface parameters using both stylus readings and image processing software for widely used end mill cutting tools that have considerable effect on characterization of sensitive manufacturing surface of millings.
