About our project

By
This project aims at designing and producing a CNC laser engraving machine. Three different alternative designs have been done and the best one was chosen. The calculations for building a CNC laser engraving machine are based on an effective working area of 300x300 mm2. Detail drawings and assembly drawing were done for the chosen design. The project was manufactured and tested to engrave on wood, plastics, leather and metals. A web blog containing project activities have been created. The project cost was 2630 S.R.

Design modification

By
In the first five weeks of the semester the design team worked on scouting the local market for the required materials and parts which were selected in the ME491 final design. Unfortunately, not all the parts were found so the design team ordered those part from international market. Some of the raw materials were found in the local market but with a different specification where the design was based on using plywood thicknesses of 20 and 25 millimeters but the only available thickness in the market was 18 millimeters so the design was modified to use those raw materials. Based on the recommendation of the advisors and the examiners the design team added a cover to the design to increase its safety and storage flexibility.
