| Summary, etc. |
This thesis focused on the development of a microcontroller-based bar feeder system for a<br/>power hacksaw, aiming to automate metal feeding and improve efficiency over traditional<br/>manual methods. The system was designed to deliver consistent feed lengths while<br/>reducing human error. The prototype underwent two tests: the accuracy of feed length and<br/>the reliability of bar feeding speed. Across all tested lengths, minor discrepancies in feed<br/>accuracy were observed, influenced by factors such as mechanical play, vibration, and<br/>sensor placement. For the 50 mm target, the mean feed was 49.8 mm (SD = 0.75), while<br/>100 mm trials averaged 99.67 mm (SD = 2.08). At 150 mm, feeds ranged from 148.5 to<br/>152 mm (mean = 149.83 mm, SD = 1.89), and 200 mm trials showed overfeeding with a<br/>mean of 213.33 mm (SD = 2.40), suggesting alignment or calibration issues. The 500 mm<br/>trials showed minimal deviation (mean = 500.67 mm, range = ±3 mm). Feeding speed tests<br/>showed that the time required for feeding increased proportionally with the feed length.<br/>The system was consistent, and there was little variance in feeding times across the<br/>different tested lengths, e.g., at 150 mm it had a standard deviation of only 0.08 seconds.<br/>Although it had some inaccuracies, it was rated at 4.24 out of 5, which is a very satisfactory<br/>rating given by both the users and the experts. Such a grade was a measure of the simplicity<br/>of use and the possibility of streamlining the working routines within the workshop<br/>scenario. Additional work is yet to be done to ensure the highest performance at long<br/>lengths. |
