Combined Drilling and Reaming Operation in Robot and CNC

Abstract

Abstract The drilling and reaming operation are two separate machining processes. In our project drilling and reaming operation are combined by using combined drilling and reaming bit. The industrial robot with agile motion is possible to machine a component. The Industrial robots with high precision and six Degree of freedom are considered as better, for manufacturing processes. This work is to significantly compare the performance of robot drilling over CNC drilling. The manipulator used is ABB - IRB1410 with work volume of 2.6 meters, handling capacity of 5Kg and controlled by IRC5 Controller. Drilling machine utilized is specified with maximum speed of 2800 RPM and power of 600W. The speed of the drilling machine can be varied by using voltage regulator. Speed and feed are the two parameter that are varied and circularity, surface roughness are the parameter checked for. The drilling operation is also done in CNC machine. The parameters such as surface roughness, circularity are checked. Finally, comparisons between robot operation and CNC operation are performed, optimized values are found by using Taguchi method.
