Abstract

Abstrak Dalam makalah ini, kesalahan radial dari spindle mesin gerinda CNC presisi tinggi yang diakibatkan oleh pengaruh gaya unbalance telah diamati. Poros spindle dianggap sebagai rotor fleksibel yang didukung oleh dua buah angular contact ball bearing. Metode elemen hingga (FEM) telah diadopsi untuk mendapatkan persamaan gerak spindle. Dalam studi ini, pertama, frekuensi natural, kecepatan kritis dan amplitudo respon unbalance ditentukan terlebih dahulu agar dapat diketahui bagaimana bentuk dari perilaku dinamiknya. Kemudian, teknik optimasi desain digunakan untuk meminimalkan perpindahan radial pada spindle yang melibatkan parameter seperti diameter poros, karakteristik dinamik bearing, kecepatan kritis dan amplitudo respon unbalance, selain itu juga untuk mendapatkan diameter poros, kekakuan serta redaman bearing yang seoptimal mungkin. Hasil simulasi numerik telah menunjukkan bahwa dengan mengoptimumkan diameter poros, kekakuan bearing dan redaman bearing, kesalahan  radial dari spindle dapat dikurangi. Spindle dengan kesalahan radial sekitar 4µm dapat dikompensasi dengan kepresisian menjadi 2 µm.   Kata kunci: kesalahan radial, metode elemen hingga, optimum desain, spindle gerinda presisi tinggi.   Abstract In this paper, radial displacement error of a high precision spindle grinding caused by unbalance force was studied. The spindle shaft is considered as a flexible rotor supported by two pairs of angular contact ball bearing. The finite element method (FEM) have been adopted for obtaining the spindle equation motion. In this study, firstly, natural frequencies, critical frequencies and amplitude of unbalance response caused by residual unbalance are determined in order to investigate the spindle behaviors. Further more, an optimization design technique is conducted to minimize radial displacement of the spindle which considers shaft diameters, dynamic characteristics of the bearings, critical frequencies and amplitude of the unbalance response, and computes optimum spindle diameter and stiffness and damping of the bearings. Numerical simulation results show that by optimizing the shaft diameters, and stiffness and damping in the bearings, radial displacement of the spindle can be reduced. A spindle about 4 µm radial displacement error, can be compensated with 2 µm accuracy.   Keywords: finite element method, high precision spindle grinding, optimization, radial displacement error.
