Opis:: Single-pass honing is used as a finishing process to meet high demands regarding form and dimensional accuracy of drilled holes. The disadvantages of single-pass honing compared to the conventional long-stroke honing are high process forces and torques as well as an increased risk of chip space clogging of the abrasive stones. Following this, the oscillation-superimposed single-pass honing without cutting fluid has been conducted in this work, which is promising when it comes to the environmentally friendly improvement of machining processes. It was shown that the omitted lubrication and flushing effect of the contact zone between the tool and the workpiece could be compensated with the aid of the superimposed oscillations. The process forces of the dry honing process are up to 37% lower compared to the conventional process, the height of the surface profile Rz decreases by 33% and the form deviations decrease up to 47%. Hence, the new method allows the saving of resources, while improving the work results.

Opis:: This paper presents the practical application of a power measurement system based on computer processing of signals generated by current and voltage sensors connected with spindle and axis driving electric motors. By using LabView data acquisition system, the total power and its components were recorded during machining operations. The experimental study concerns the power consumption and surface roughness produced in a sequential machining process consisting of hard turning and ball burnishing operations under variable machining parameters. In particular, some machining routines including finish hard machining and both single and multi-pass ball burnishing of hard surfaces were performed and compared. Finally, the optimization procedure based on these technological criteria was proposed.

Opis:: Quality of Surface Finish on Furniture Doors of MDF Board. The paper deals with the assessment of the quality of furniture door surface. The properties were tested on the following types of the surface finish on MDF doors: PVC foil (glossy and matt), acrylic foil, and PUR pigmented coating material. The following physical and mechanical properties of the surfaces were assessed: the film hardness, the impact resistance, and the resistance against scuffing. The polyurethane surface finish and the glossy PVC foil achieved the same film hardness. The impact resistance of the polyurethane finish was significantly lower than the impact resistance of the PVC foils and the acrylic foil. The resistance against scuffing was lower for the polyurethane finish if compared to the foiled surfaces.
Jakość wykończenia powierzchni drzwi meblowych z płyty MDF. W ramch artykułu zbadano właściwości powierzchni drzwi z płyty MDF o trzech rodzajach wykończenia: folia PVC (błyszcząca i matowa), folia akrylowa i pigmentowany materiał PUR. Określono następujące właściwości fizyczne i mechaniczne powierzchni: twardość folii, odporność na uderzenia i odporność na ścieranie. Powierzchnie wykończone PUR i błyszczącą folią PCV charakteryzowały się zbliżoną twardością. Odporność na uderzenia powierzchni wykończonej poliuretanem była znacznie niższa niż odporność powierzchni wykończonych folią PVC i folią akrylową. Powierzchnia wykończona PUR charakteryzowała się niższą odpornością na ścieranie w porównaniu z pozostałymi badanymi wykończniami.

Tytuł:: The influence of cutting parameters on surface topography during turning marine pump shafts

Opis:: One of the greatest problems of modern production techniques is the achievement of an appropriate quality at minimal costs and accompanied by the production efficiency increase. Therefore, while designing the production process. The technology used should have a considerable influence on the durability and reliability of machine parts to be produced. During finish treatment, the final dimensions as well as functional properties are imparted to a given element by application of proper treatment type. The engineer has a range of production techniques to choose for the proper surface layer formation. Conventional turning machines belong to the basic equipment of ships, because in sea conditions, they enable the execution of a spare part or carrying out the necessary operations in the process of their regeneration. The use of modern cutting tools makes it possible to obtain a surface with low values of surface roughness parameters. The use of new generation cutting inserts on conventional lathes can cause problems for operators. The lack of the ability to ensure proper of treatment condition and setting errors of cutting tools contribute to the damage of the cutting insert or the surface of the workpiece. The article presents the results of influence of different cutting parameters on surface topography during turning process of stainless steel. A shaft made of 304L stainless steel was used for the research. The cutting process was carried out on a universal TUM 25B x 500 centre lathes. During the turning the following machining parameters were used: cutting speed Vc [m/min], feed f [mm/rev] and depth of cut ap [mm].The turning process was conducted by a cutting tool with CCGT 09T302 UM, CCGT 09T304 UM and CCGT 09T308 UM inserts. Measurement of surface topography was carried out by T8000 profilometer.

Opis:: In this paper, the analysis of vibrations on surface roughness generated during boring with the application of the conventional boring tool and one with the damper is presented. The experiments included the measurement of vibration accelerations carried out with the piezoelectric sensor, as well as the evaluation of surface roughness parameters after each machining pass. The obtained results reveal that in the investigated range, no stability loss was found. Furthermore, the growth of the rotational speed induces the increase of vibration level, as well as the growth of the differences between the vibration values generated during boring with the conventional tool and one equipped with damper. Vibrations have also the direct influence on the machined surface roughness. In case of the tool equipped with the damper, the tool’s overhang L had more intense influence than rotational speed n. However, for the conventional boring tool this dependency was unequivocal.

Opis:: This paper describes findings in the surface topography of Ti6Al4V alloy after finish turning process under dry and MQL (minimum quantity lubrication) machining. The research was fulfilled in the range of variable feeds per revolution of 0.005-0.25 mm/rev and cutting speeds of 40-100 m/min using the depth of cut of 0.25 mm that fits finish processing conditions. The test plan was developed on the way to use the Parameter Space Investigation (PSI) method. The topography features were measured by a Sensofar S Neox optical profilometer using the Imaging Confocal Microscopy technique. Ra parameters and surface roughness profiles as well as 2D images and contour maps were analyzed. Under the studied machining conditions, lower Ra roughness parameters are obtained in the feed rate of 0.005-0.1 mm/rev and cutting speeds of 40-60 m/min. In comparison with dry machining, up to 17% reduction in Ra parameter values was obtained using the MQL method and vc = 70 m/min and f = 0.127 mm/rev as well as vc = 47.5 m/min and f = 0.22 mm/rev. Depending on the machining conditions, peaks and pits as well as feed marks typical for the turning process are observed on the machined surfaces.
