Abrasive blasting modifies the surface state of pre-treated materials in terms of surface irregularities. Bearing in mind that the roughness characteristics affect the components functionality, it is essential to study and evaluation the surface state of pre-treated materials. The paper deals with evaluation of relation between individual parameters of roughness of the blasted surfaces by the correlation analysis. Based on the measured values on the surfaces which were blasted by various types of blasting devices, the correlation matrix was set and the standard of statistic importance of correlation between the monitored parameters was determined from it. The correlation coefficient was also set. There were found regression models using ANOVA (ANalysis Of Variance). Based on the analysis of the results were also proposed sets of roughness parameters, which can be used in the assessment of the blasted surfaces.

“…Some relevant research results were presented by authors previously in [ 1 ] about burnishing of rotary components. Moreover, the elimination of surface profile generated after turning brake disks was also analyzed by authors applying abrasive brushes [ 2 ]. Turning operation always induces a kinematically defined pattern, with spirals on part surfaces or thread-like profiles.…”

Roller burnishing technique to achieve isotropic surface topography on cylindrical components made of austempered ductile iron (ADI) casting is presented in this paper. In the last years, ADI casting components are used in many mechanical applications, due to their enhanced mechanical properties. ADI castings are difficult-to-cut materials; therefore, advanced techniques to improve manufacturing productivity are necessary and under research. On the other hand, spiral roughness pattern produced by turning operation is a common source of unconformities in several applications. Turning produces a defined kinematic pattern, similar to a thread. This work presents a theoretical and experimental validation using different burnishing conditions. Roughness and surface topography and surface integrity were checked. Results show that the technique greatly improves surface roughness, and eliminates the kinematic-driven roughness pattern of turning, leading to a more isotropic finishing. A comparison between roller burnishing and ball burnishing is also presented in this paper.

Measurements of Forces and Selected Surface Layer Properties of AW-7075 Aluminum Alloy Used in the Aviation Industry after Abrasive Machining

Measurements of forces during machining, especially thin-walled structures typical of the aviation industry, are important in the aspect of instability caused by vibration. One of the last stages of manufacturing by machining is the finishing treatment and deburring of the product’s edges. Brushes with ceramic fibres are often employed in deburring, especially for large-sized elements specific to the aviation industry due to the possibility of automatic machining directly on machining centres. This study set out to analyse the effect of variable brushing conditions on axial forces and the selected surface layer properties of AW-7075 aluminium alloy. Experimental studies have examined factors such as surface roughness and topography, axial cutting force in ceramic brush treatment and surface free energy in the aspect of adhesive joints. The tested variable process parameters were the fibre material and the adjustment sleeve spring stiffness. Based on the tests, it was found that the axial force applied by the brush was more strongly connected with the spring stiffness rather than the type of bristle. For most cases, an increase in the value of free surface energy after brushing was observed compared to the initial machining which was milling.
