Titanium Alloy Deep Hole Jacking Processing Mechanics Characteristic Experimental Research

Taking TA1 titanium alloy deep hole trepanning mechanical properties as the research object, in view of the titanium alloy material physical and mechanical processing properties, this paper develop of a outside chip discharge trepanning drill of a diameter 117mm, choose different cutting parameters to conduct trepanning processing, separately measure the axial force and torque on the drill pipe. Through the analysis of test data, we can obtain that when the spindle rotational speed is constant, the axial force and torque with the feed rate increases, and when the feed rate is constant, the axial force and torque will increase with the feed rate, while the feed rate is constant, the axial force still increase with the spindle speed increase, but the torque decrease with the spindle speed increase and tool wear and tear aggravate with the increase of cutting parameters.
