Abstract
t is well known that slender rod machining operation is a very difficult problem due to its low stiffness. During slender rod machining process, the deflection, vibration, cutting heat and cutting force of the machined part are the main reasons affecting the product quality. Based on the analysis of current research status of slender rod milling technology, process scheme, milling strategy, clamping fixture and tool designing is carried out in this work. In a roughing milling stage, we create a new strategy of square rod milling, called equilateral milling strategy to eliminating deflection. In finish-milling top waveform stage, a way using semicircle profile cutter to finish was applied. Complex interpolated movement is transform into simple two-dimension curved movement to shorten machine time and increase of efficiency in the way. In addition, machined surface with burnishing effect, high precision and high surface quality is obtained.
