“…If b is positive, the direction of the patterns is counterclockwise, but clockwise vise versa. The best surface quality can be obtained, when the phase shift, which is the fractional part of the frequency ratio, is 0.5 [47,48]. Further, Zhou and Cheng [49] introduced an integrated simulation-based approach to bridge the gap between the cutting process and the surface topography/texture generation.…”

“…28 It is difficult to obtain an optimal balance between the flexibility and rigidity of the bonnet polishing tool. 29 Magneto-rheological jet finishing (MJF) was invented by QED Technologies (NY USA) to break through the limitations of the MRF process. 30 In the MRF process, interference between the large curvature polishing tool and steep concaved surfaces with small curvature always exists.…”

Components with super-smooth freeform surfaces are being applied more and more extensively in various fields. Among the valuable non-traditional finishing processes for generating super-smooth freeform surfaces that have been developed, the two-axis vibration assisted polishing process has attracted great attention from some scholars in recent years. However, in the existing two-axis vibration assisted polishing process, vibrational coupling occurs between the traverse and axial directions in the vibrating body and causes the actuating polishing tool to rotate, which limits the polishing effect. To solve the above-mentioned vibration coupling problem, herein we develop a novel two-dimensional ultrasonically actuated polishing process using two mutually perpendicular Lange in vibrators. Through theoretical analysis and experimental tests, the influences of the contact pressure, feed rate, and vibrational parameters on the material removal rate of the proposed polishing process were revealed. The experiments demonstrated that the polishing removal rate was greatly improved.

“…Advantages of a 6-degree of freedom (DOF) robot, compared with other machines used for polishing process, are mainly related to the low investment that robot purchase supposes in comparison with milling machines, 6 turning machines or special machines. 7 Recently, some intends to develop an automated polishing system based on robotics. There are two main concepts that can be used.…”

Polishing process is one of the most critical manufacturing processes during a metal part production because it determines the final quality of the product. Free-form surface polishing is a handmade process with lots of rejected parts, scrap generation and time and energy consumption. Two different research lines are being developed: prediction models of the final surface quality parameters and an analysis of the amount of material removed depending on the polishing parameters to predict the tool footprint during the polishing task. This research lays the foundations for a future automatic conformal polishing system. It is based on rotational and translational tool with dry abrasive in the front mounted at the end of a robot. A tool to part concept is used, useful for large or heavy workpieces. Results are applied on different curved parts typically used in tooling industry, aeronautics or automotive. A mathematical model has been developed to predict the amount of material removed in function of polishing parameters. Model has been fitted for different abrasives and raw materials. Results have shown deviations under 20% that implies a reliable and controllable process. Smaller amount of material can be removed in controlled areas of a three-dimensional workpiece.
