Abstract
Penentuan posisi spindle merupakan hal yang penting dalam penggunaan mesin Computerized Numerical Control (CNC). Hal ini disebabkan karena pada spindle terdapat mata bor yang merupakan komponen utama dalam pembentukan benda kerja. Penentuan posisi spindle memerlukan kecepatan, kestabilan dan keakuratan yang tinggi. Namun, kemampuan CNC untuk memenuhi kebutuhan tersebut dipengaruhi oleh beberapa faktor yang dapat mengurangi kualitas dari hasil mesin CNC. Faktor-faktor tersebut antara lain pembebanan akibat benda kerja, keausan mata bor, dan rancangan mekanik dari mesin CNC. Tugas akhir ini bertujuan untuk meningkatkan kualitas mesin CNC. Hal tersebut dilakukan dengan meningkatkan keakuratan dan kecepatan respon servo motor pada CNC, karena servo motor memiliki peran untuk mengatur posisi dari mata bor yang sangat vital terhadap hasil dari mesin CNC. Metode yang digunakan adalah Fuzzy-PD. Kontroler Fuzzy-PDmemiliki fleksibilitas dalam mengahadapi kondisi mesin CNC yang dinamis.Hasil simulasi menunjukkan bahwa kontroler Fuzzy-PDmemiliki kemampuan untuk beradaptasi dengan kesalahan yang terjadidan tahan terhadap gangguan. Kontroler Fuzzy-PD terbukti dapat mengurangi overshoothingga nol serta meningkatkan kecepatan respon hingga 8,27 detik. ========== Spindle positioning is substansial in machine Computerized Numerical Control (CNC). This is because of the drill on spindle is a major component in the shaping of the workpiece. Spindle positioning requires speed , stability and high accuracy. However , the ability to fulfill the needs of CNC is influenced by several factors that can reduce the quality of the results of the CNC machine. These factors are due to the imposition of the workpiece, the worn-out drill, and mechanical design of the CNC machine. This final project aims to improve the quality of the CNC machine. This is done by increasing the accuracy and speed of response in the CNC servo motors, because it has a role to adjust the position of the drill that is vital to the product of CNC machine. Fuzzy–PD controller is chosen as method to meet the objective. This controller has the flexibility in facing dynamic changing of CNC machining conditions. Based on simulation result, Fuzzy-PD controller has the ability to adapt and also resistant to interference. Fuzzy-PD controller is able to reduce the overshoot into zero and increase the response speed up to 8.27 seconds.
