Study on Drilling Characteristics of Supper Alloy GH3039

Abstract:

This paper explores the drilling characteristics of GH3039 supper alloy. The machining of GH3039 is a difficulty which is commonly used in aircraft and engineer components of the aerospace industry. The spindle speed and feed per tooth are the major influence factors which are studied to gain large removal rate and predict the drilling characteristics. So the single factor test is carried out about spindle speed and feed per tooth. The results of the experiment show that the drilling force of GH3039 decreased with the increasing of spindle speed up to 900r/min which is larger than other metal drilling process. The small feed per tooth may obtain small drilling force. So too low spindle speed and large feed per tooth are not adopted in the GH3039 drilling process. The analysis of the chip formation also verifies the above characteristics. At the same time, the serious serrated chip is occurred which is adverse for the drilling. It has significant for other supper alloy real drilling process.
