Research on Modeling and Simulation of Surface Topography Obtained by Trochoidal Milling Mode with Ball End Milling Cutter

Surface roughness prediction and roughness reliability evaluation of CNC milling based on surface topography simulation

“…( 29), and a total of 2n+1 sample points are obtained by combining the center points 𝑋 (𝑘) . where the center point of the first iteration 𝑋 (1) = 𝜇 𝑥 = (𝜇 1 , ⋯ , 𝜇 𝑖 , ⋯ 𝜇 𝑛 ), 𝜇 𝑥 is the mean point of the fundamental random variable.…”

“…With the rapid development of manufacturing technology, the surface integrity of parts has received great attention in related fields. The formation mechanism of surface geometries and the modeling process are important components of surface integrity studies, which mainly includes irregular micro-geometries such as surface roughness, waviness, and shape error [1] . The formation of surface topography of the part is a complex process, it is through the relative motion of the tool on the surface of the workpiece to remove the material to form different shapes and sizes of bumps and valleys.…”
