The use of CNC machines is increasing rapidly, along with factory automation. Therefore, the need for skilled CNC machine design experts is increasing. The development of a CNC lathe that is strong and easy to move from one place to another is a necessity for educational institutions with limited space to practice CNC lathes for their students. In this research, the design and manufacture of a strong and self-produced 2 axis mini-lathe machine prototype were carried out. The method used in designing the structure of the machine, and selecting the electric motor to drive the spindle, and the stepper motor to drive the chisel. The results of this study obtained a 2 axis mini-lathe CNC machine with predetermined electronic components, so that it has a design torque of the spindle motor of 4.7454 Nm and a speed of 1,500 rpm, with a stepper motor power of 36 W, with a cutting speed of 90 m min. This CNC machine can work on aluminum material in the experimental process of the infeed depth used is 0.5 mm/rotation with a maximum cutting speed (feed-rate) of 0.75 m/minute. It is recommended to use a low feed rate in machining. The axial force on the stepper motor is 1,368 N with a tool pressure when machining of 912 MPa so that it can cut the A6061 type aluminum material with a yield point of 145 MPa. In the future research can be developed using a material that is tougher than aluminum in order to measure the maximum capabilities of the machine.Penggunaan mesin bubut yang dikendalikan oleh computer numerical controlled (CNC) dengan kecepatan tinggi dan akurasi dimesi yang bagus, sehingga penggunakan tenaga kerja yang lebih sedikit.

Abstract

Sungai Itik Village is located in Sungai Kakap District, Kubu Raya Regency, directly visiting Pontianak City. However, the people in Itik Village have not yet enjoyed clean water from the local water company. So that the surrounding community uses clean water sourced from rainwater or drilled wells. However, the condition of the well water is not yet suitable for use. At the As-Siddiqiyah Islamic Boarding School, it has drilled wells with a flow rate of 30 liters/minute and does not need to be sucked up with a water pump in flat, level conditions. However, the condition of the water still contains a lot of Fe2+ ions, has a metallic smell and color. This drilled well water is very possible as raw water to be processed and used as drinking water that can be consumed by the community around the Islamic boarding school. The Student Creativity Program Team of the Faculty of Engineering provides air purification solutions with the Aeration, Sedimentation and Filtration methods contributing to the local community, especially for students at Islamic Boarding Schools. The results of laboratory tests on drilled well water at the As-Siddiqiyah Islamic Boarding School show that raw water that has been treated through water treatment equipment is suitable for daily activities and does not cause health problems. The provision and management of clean water is left entirely to the students in Islamic boarding schools to maintain the continuity and maintenance of the availability of clean water.
