“…Much work about the material removal depth has been done. Zhao et al (1995) proposed the experimental expression of the material removal depth. The material removal depth is directly proportional to the relative velocity at polishing point, mean pressure and number of polishing times and inversely proportional to feed rate and workpiece hardness.…”

“…A more detailed schematic of the polishing spindle is shown in Figure 3(b). As indicated by Zhao et al, 19 the normal force plays an important role on the material removal during the polishing. For the deterministic polishing process, the normal force should be under control during the polishing process.…”

“…16–18 For the polishing process with a spherical tool, a small normal force corresponds to a small size of the contact region, which would result in low efficiency. 19 On the other hand, although the large normal force would enlarge the size of contact, the pressure in the contact region also increases, which would damage the surface easily and lead to severe tool wear. For the part surface of medium size, it is not very stable to polish by a spherical tool.…”

The high-precision part surfaces are usually finished by the corrective polishing to improve the surface form accuracy. This article proposes a new method to model and optimize the material removal in the polishing process. This method assumes that the material removal rate in polishing follows the Preston’s equation, and the material removal profile is obtained by integrating the material removal index along the tool path at each unit area of the tool/workpiece contact. The focus is on the effect of the sliding velocity on the material removal profile. Results indicate that the shape of the removal profile is affected by the angular spindle velocity, angular feed velocity and tool path radius. A series of simulation and practical polishing experiments were conducted to verify the proposed model. The tending gene of the removal profile is defined and derived. By using the principle of maximum tending gene, the material removal profile is optimized, which is helpful to plan the process parameter properly in polishing.

Freeform surfaces are being used in a multiplicity of applications in different kinds of industries related to Bio-medical (Bio-implants), micro channels in micro fluidics, automotives, turbine blades, impellers of artificial heart pumps, automobiles etc. Different parts in these industries need nano-level surface finish as their functional inevitability. It is very difficult and challenging to achieve high level of surface finish, especially on the components having freeform (or sculptured) surfaces, complex shapes, and 3-D features. Surface finish is a significant factor, which affects life and functionality of a product. Many traditional and advanced finishing processes have been developed for finishing of freeform/sculptured surfaces but still it has not been possible to achieve uniform nano level surface finish specially in case of freeform surfaces. To overcome the limitations of the existing nanofinishing processes, researchers are developing new processes for uniform nanofinishing of freeform surfaces. In this article, an attempt has been made to review different nanofinishing processes employed for freeform surfaces useful in different types of applications. In addition, experimental work, theoretical analysis and existing challenges of the finishing processes have been identified to fill the research gap.
