Effects of Flap Wheel Grinding Parameters on Surface Roughness for Stainless Steel

Abstract

The polishing process plays an important role in the stainless steel cookware since an appearance is one of the prime quality criterions of the product. Typically, there are three sequential steps in the polishing process using abrasive flap wheel, sisal and cloth respectively. The abrasive flap wheel is the first step in the process which aims to rapidly create fine surface finish on the product. Thus, the selection of appropriate flap wheel as well as operating conditions in order to achieve surface finish within the required cycle time i.e. 12 seconds are the key success factor. Therefore, the experimental design is conducted and analyzed. It is found that there are four factors which influence the surface roughness: grits size of flap wheel, polishing time, velocity, and force. It can also be concluded from the analysis that the roughness is directly proportional to grit size and force but it is inversely proportional to velocity. In addition, the optimal condition for the case study can also be obtained.

Özel Kesit Profil Flap Diskinin Üretim Performansının Belirlenmesi

“…Ancak özel tasarım flap diskler üzerine herhangi bir çalışma bulunmamaktadır. Sornqurnnerd J. ve arkadaşları, 2014 yılında yaptıkları çalışmada paslanmaz çelik malzemeden iş parçasının flap disk ile çapak alma ve talaş kaldırmada taşlama parametrelerinin yüzey pürüzlülüğü üzerine etkilerini incelemişler ve grit ve flap disklerin boyutlarının, taşlama zamanının, hızın ve kuvvetin önemli olduğunu vurgulamışlardır [4].Bir diğer çalışmada, yüzey pürüzlülüğünü etkileyen önemli faktörler arasında kesicinin tasarımı, geometrisi, kesme derinliği ve kapasitesinin debulunduğu belirtilmiştir [10][11].…”

Effect of polishing disc compliance on the pressure distribution and material removal

“…There are different varieties of flap wheels, where foambased flaps, non-woven type flaps, etc. are available [16,17] . Belt type finishing is one of the common polishing used in industries, robot or CNC assisted to polish complex 3D parts [18,19].…”

“…There are only a few studies that used experiments to study the contact pressure distribution, that makes this topic more explorable. 17 The experimental contact pressure was obtained by stacking the pressure films of various pressure ranges together.…”

“…17 shows the different tool positions (I, M, R). The dynamometer helps to confirm that on a constant force was maintained for the 3 seconds of machining time.…”
