整形过程的重要性及其对磨削过程和最终工件表面光洁度的影响已得到广泛证明。之前的工作表明，单点金刚石修整优先用于精加工操作，而金刚石转盘修整仅适用于粗加工操作和使用氧化铝砂轮磨削时单道次去除大量坯料。本研究的目的是检验之前的研究结果对热压CBN砂轮的适用性，并确定金刚石转盘修整过程中最有影响的修整参数。

THE IMPORTANCE OF THE TRUING PROCESS AND ITS EFFECT ON THE GRINDING PROCESS AND FINAL WORKPIECE SURFACE FINISH HAS BEEN WIDELY DEMONSTRATED. PREVIOUS WORK DEMONSTRATED SINGLE POINT DIAMOND TRUING IS PREFERRED FOR FINISHING OPERATIONS, AND DIAMOND ROTARY DISC TRUING IS SUITABLE ONLY FOR ROUGHING OPERATIONS AND LARGE STOCK REMOVAL DURING A SINGLE PASS, WHEN GRINDING WITH ALUMINUM OXIDE WHEELS. THE PURPOSE OF THIS RESEARCH IS TO TEST THE PREVIOUS FINDINGS FOR THEIR APPLICABILITY TO HOT-PRESSED CBN GRINDING WHEELS, AND TO IDENTIFY THE MOST INFLUENTIAL TRUING PARAMETERS IN THE DIAMOND ROTARY DISC TRUING PROCESS.
