WITHDRAWN: Measurement of Micro Burr and Slot Widths through Image Processing: Comparison of Manual and Automated Measurements

Abstract

In this study, the burr and slot widths formed after micro-milling process are investigated using a rapid and accurate image processing method. The measurements are obtained by processing the images and results were compared with a manual measurement method. In the cutting experiment stage, Inconel 718 alloy was chosen as the workpiece and cutting tools with various specific properties were used. The images of the burr and slots were captured using scanning electron microscope (SEM). Different tool geometries and cutting parameters were considered for choosing the SEM images. Captured images were processed with a computer vision software which was written in C + + programming language and open-sourced computer library (Open CV). The demonstrated approach was successfully measured the slot and burr widths in plain and complex conditions where slot and burr are nested. According to the close findings of manual and automated measurements, it was observed that burr widths increased especially at the down milling sides and slot widths decreased due to the increased cutting length. Specific tool properties such as number of cutting edge, helix angle and cutting length affected the slot and burr widths. It was determined that there is a good correlation between automated and manual measurements of slot and burr widths. The accuracy of the proposed method is above 91%, 98%, and 99% for up milling, down milling, and slot measurements, respectively.

“…Bu nedenle çapakların minimize edilmesi için kesici takım test edilerek belirli periyotlarla izlenmesi gerekmektedir. Böylece parça yüzeyinde istenilen toleranslar sağlandığında uygulanan kesme parametresi kabul görecektir [23][24].…”

THE EFFECT OF MACHINING PROCESSES ON THE PHYSICAL AND SURFACE MORPHOLOGY OF Ti6Al4V SPECIMENS PRODUCED THROUGH POWDER BED FUSION ADDITIVE MANUFACTURING

“…Metals are converted into products by adding value through manufacturing methods such as machining, welding, powder metallurgy, casting, plastic forming, and unconventional manufacturing methods [1][2][3]. Machining is the general name of removing parts in the form of chips with cutting tools from the surface of the material to bring raw material to the desired final shape and size in a controlled manner [1,2,4].…”
