“…The index is affected by the integrated operations of various factors namely CAD/CAM, CNC controller, servo control, feed drive system, and mechanical bodies [12]. Another possible effector which often neglected is probe hysteresis [17] and the subsequent deformation [18]. Improving machining precision has been a widely known challenge in industry as the CNC machine is composed of various moving and rotating shafts that makes machining motion complicated [19].…”

“…Bu doğrultuda palelerin mekanik pimli fikstürlere sabitlenmesi ve/veya sonrasında işlenmesi sırasında ortaya çıkan kuvvetlerin parçada oluşturduğu deformasyon seviyeleri araştırılmaktadır. Bunlar araştırılırken malzemelerin mekanik (elastik ve/veya plastik) özelliklerine ihtiyaç duyulmaktadır [9], [13], [14]. Malzeme özelliklerine ek olarak dikkat edilmesi gereken diğer hususlar arasında sınır koşulları (İng.…”

“…Blade, as one of the most used functional part in aero-engine, is the key part for the realization and improvement of aero-engine performance. Near-net-shaped blade, such as precision-forged blades without margins, precision-cast blades without margins, will be the future development trend due to the complex curved surface of near-net-shaped blade is directly formed by the forming process without the material removal link on the blade surface, which can improve the blade body anti-fatigue performance under the high temperature, high pressure and high speed conditions [1]. Figure 1 is a typical near-net-shaped blade formed by the precision forging forming process, the contour error of the blade body is in the range of 0.008mm to 0.05mm, which meets the accuracy requirements of the blade body and does not require subsequent CNC machining process.…”
