The Investigation of Prediction Surface Roughness from Machining Forces in End Milling Processes

Abstract

Surface roughness is one of the most significant parameters to determine quality of machined parts. Surface roughness is defined as a group of irregular waves in the surface, measured in micrometers (μm). Many investigations have been performed to verify the relationship between surface roughness and cutting parameters such as cutting speed, feed rate and depth of cut. To predict the surface produced by end milling, surface roughness models have been developed in this paper using the machining forces by assuming the end mill cutter as a cantilever beam rigidly or semi- rigidly supported by tool holder. An Aluminium workpiece and solid carbide end mill tools are used in this work. Model to predict surface roughness has been developed. Close relationship between machined surface roughness and roughness predicted using the measured forces signals.

On-Line surface roughness classification for multiple CNC milling conditions based on transfer learning and neural network

“…Though the off-line prediction models of surface roughness lay foundations for designing the machining parameters, they do not consider the effects of uncertain factors in the machining process on the surface roughness, such as the vibration, chip residue and so on. Therefore, many researchers have focused on constructing the on-line prediction models of the surface roughness with the aids of measured dynamic information such as milling force signals and acceleration signals [15][16][17][18]. García et al [19] proposed two methods for enhancing the surface roughness monitoring, including the individual analysis of principal components and the grouping analysis of correlated principal components, and the grouping analysis of correlated principal components proved to be a more efficient method.…”

The Study of Surface Finish in Face Milling of Stainless Steel: AISI 304

“…Then, choosing cutting tools and based on condition of feed, speed, and of cut to machine material could be affected to quality of product especially in this case is surface roughness [2]. Cutting tool as carbide tool is of many tools used for cutting material to have a good quality of surface roughness because it provides better solution for this [3]. Therefore, based on these conditions to have better surface roughness for milling material especially stainless steel, the objectives of this study were to study the factors, which were speed, feed, and coolant affected to surface roughness of milling stainless steel (AISI/SUS 304).…”

“…Previous study reported that effect of milling parameters in various process on surface roughness. Such as, the milling operation and factors affected to finished surface of medium carbon steel [2], aluminum [3], cobalt-based alloy [4], titanium alloy [5,6], mold steel [7] and polymer [8].…”

The Effects of Milling Factors on Surface Finish of Chromium-Molybdenum Steel

“…The previous studies for surface finish of steel such as stainless steel [1], medium carbon steel [2][3] were studied. The others material has been studied such as titanium alloy [4][5], nickel alloy [5][6], aluminum alloy [7] and polymer [8]. They conclude that conditions of milling parameters based on feed rate, cutting speed, and depth of cut could be affecting to surface finish especially in case of steel.…”
