Experimental study on energy consumption of computer numerical control machine tools

Machining processes are responsible for substantial environmental impacts due to their great energy consumption. Accurately characterizing the energy consumption of machining processes is a starting point to increase manufacturing energy efficiency and reduce their associated environmental impacts. The energy calculation of machining processes depends on the availability of energy supply data of machine tools. However, the energy supply can vary greatly among different types of machine tools so that it is difficult to obtain the energy data theoretically. The aim of this research was to investigate the energy characteristics and obtain the power models of computer numerical control (CNC) machine tools through an experimental study. Four CNC lathes, two CNC milling machines and one machining center were selected for experiments. Power consumption of non-cutting motions and material removal was measured and compared for the selected machine tools. Here, non-cutting motions include standby, cutting fluid spraying, spindle rotation and feeding operations of machine tools. Material removal includes turning and milling. Results show that the power consumption of non-cutting motions and milling is dependent on machine tools while the power consumption of turning is almost independent from the machine tools. The results imply that the energy saving potential of machining processes is tremendous

Peningkatan Kemampuan Sistem Operasi Mesin Milling Cnc Trainer Dengan Mengadaptasi Luaran Perangkat Lunak Mastercam

Kebutuhan operator semakin meningkat dengan semakin meningkatnya persaingan antar Perusahaan. Namun, hal ini masih menjadi persoalan. SMK tidak dapat menghasilkan operator yang berkompeten dikarenakan SMK belum bisa menyediakan mesin CNC (Computer Numerical Controlled) sebagai fasilitas pembelajaran untuk para siswanya. Laboratorium Proses Produksi Jurusan Teknik Mesin mencoba menyelesaikan masalah ini dengan membuat mesin milling CNC trainer. Namun, mesin ini tidak dapat beradaptasi dengan perangkat lunak CAD/CAM. Tugas akhir ini bertujuan agar mesin milling CNC trainer dapat beradaptasi dengan luaran perangkat lunak Mastercam. Operator hanya perlu menggambar benda kerja dan membuat simulasi pada perangkat lunak Mastercam. Pembuatan gambar dapat menggunakan perangkat lunak CAD ataupun CAM. Proses penelitian ini menggunakan perangkat lunak Delphi dengan menambahkan tombol START, DO IT, DONE dan INC. Masing-masing tombol mempunyai fungsi yang berbeda. Tombol-tombol dibuat dengan memilih tombol bitbtn pada menu yang tersedia. Program dibuat dengan menggunakan pernyataan kondisional (if-then-else) dan Perulangan (for dan while). Penulisan program selalu memperhatikan tipe data, contohnya : integer, real, boolean, arrayofstring dan string. Luaran perangkat lunak Mastercam mempunyai standar penulisan yang berbeda dengan standar penulisan mesin milling CNC trainer. Standar penulisan mesin milling CNC trainer adalah N ... G ... X ... Y ... Z ... F ... untuk selain kode G00. Untuk kode G00 yaitu N ... G ... X ... Y ... Z .... Hasil penelitian ini adalah luaran perangkat lunak Mastercam dapat beradaptasi dengan standar penulisan mesin milling CNC trainer
