One of the technologies that can be used to support the efficiency process and guarantee of good product quality is to use CNC machines. CNC machines are production machines whose controls use computers and numerical programming. CNC machines can work faster and flexible with a very high level of precision. To operate the CNC engine, operaotor is needed that is able to create a numeric program used to control the movement and coordinates of the spindle on the CNC machine.

SMK N 1 Losarang, as a vocational high school that prepares graduates to meet the criteria needed by employment, both in the business world/ industry, government agencies, entrepreneurs independently, and continue to tertiary institutions also require skills related to NC Programming for this CNC-Milling machine. Seeing this, the Telkom University Industrial Engineering S1 Community Service Team consisting of Denny Sukma Eka Atmaja, ST, MT (Chair), Rino Andias Anugraha, ST, MM (Members), and Ayudita Oktafiani, ST, M.Sc (Members), see the need to share knowledge sharing related to NC Programming for CNC-Milling Machines through CNC-Milling Machines through CNC-Milling activities. This community service activity was held on October 24, 2020 online which was attended by 14 teachers of SMK N 1 Losarang. The material provided in this training includes manufacturing, computer aided design (CAD), computer Aided Manufacturing (CAM), Cam Milling, and Cam Turning. The following is the documentation of the implementation of community service activities carried out:
