Abstract

The motion of work piece that has relative slow characteristic on procces of feeding 3 axis CNC Milling machine affect the synchronization of X and Y axis. The out of sync between the two axis cause contour error. The materials of manufacturing that has solid form cause the contour error cannot be fixed. This research propose Predictive control with Modified Cross-Coupled Control to predict the contour error.The Predictive Modified Cross-Coupled Control (PMCCC) method can reduce linear contour error that’s compared with PI Modified Cross-Coupled Control method. However, for circular contour error, the result of proposed method cause contour error worse. =========== Pergerakan meja kerja (work piece) yang relatif lambat pada proses feeding mesin CNC Milling 3 aksis mempengaruhi sinkronisasi aksis X dan Y. Tidak sinkron antara dua aksis ini menyebabkan terjadinya kesalahan kontur. Material manufaktur berbentuk zat padat mengakibatkan kesalahan kontur tidak dapat diulang lagi. Penelitian ini mendesain kontrol Predictive dengan kombinasi Modified Cross-Coupled Control untuk memprediksi kesalahan kontur. Metode Predictive Modified Cross-Coupled Control (PMCCC) mampu mereduksi kesalahan kontur linear dibandingkan dengan menggunakan metode PI Modified Cross-Coupled Control. Namun, untuk kesalahan kontur circular metode Predictive Modified Cross-Coupled menghasilkan kesalahan kontur yang lebih besar.
