Abstract
Measurement of surface roughness is one of the quality control processes, usually carried out off line. Contact type surface roughness measurement method is commonly used in quality control. The processes consume lot of time with human interaction. In order to reduce or to eliminate non value added time, effective quality inspection tool and automation of the processes has to be utilized. An attempt has been made to automate the process with integration of vision camera in capturing the image of the component surface. The image process technique has the advantage of analyzing the single captured image for multiple area measurement. Hence, the in-line quality control of each component surface roughness measurement is ensured. The automation process involves component movement, image capturing, image processing, and decision making, using sensors, actuators and microcontroller. The proposed in-line quality control of surface roughness with vision system has been successfully developed. The designed automated system has fulfilled the objectives in respect of the scope of the present work.
Highlights
Over the past decades, the need of the mankind has demanded increase in productivity with the improved quality of the products
Surface roughness value is picked corresponding to intensity factor value
The design intention is achieved successfully and below shows the developed Graphical User Interface (GUI) window for acceptance and rejection process, time taken for the test are shown in table 1 and the red box shown in GUI can be moved to any point within the sample snapshot boundary
Summary
The need of the mankind has demanded increase in productivity with the improved quality of the products. This has led to innovations, and these innovations have transformed the traditional manufacturing to advanced manufacturing. There are several methods of quality checking One such activity in the manufacturing process is the quality inspection of components’ flat surface roughness. Some of the contact type surface roughness measurement methods are Stylus Profilometry, Atomic Force Microscopy etc. The disadvantage with laser technique is limited working distance [2]. All these surface roughness quality checking methods require an atmosphere free from vibrations, dust, and heat
