The Invention of Semi-automatic Lathe Wood

บทคัดย่อ

This research aims to study the condition of semi-automatic lathe wood and to develop a semi-automatic lathe wood to be effective in processing wood products. It is an experimental research in which a semi-automatic lathe wood was experimented with eucalyptus, mango, acacia, tamarind and teak wood and their components. The dependent variable and performance level testing are independent variable. From the experimenting of the wood suitability in both the X-axis and Z-axis directions, it was found that duration, length and depth are related to the blade size. The ideal wood for turning is a trial with a 35 mm X-axis blade size. The smallest wood that can be turned is a teak of 22mm. within the specified working time of 4 minutes in the Z-axis coordinate of 40 mm. While the shortest wood turned within the same time is also a teak of 32 mm. In conclusion, a teak is the most suitable wood for turning work; the wear of the wood turning knife in the X-axis, was related to the hardness of the wood which shows that wear varies with the wood hardness; while in the Z-axis, hardwoods as teak and tamarind do more damage to the blade than eucalyptus, acacia, and mango woods. The semi-automatic lathe wood developed by researchers can be used more effectively, faster, and better in production applications for a suitable wood as teak that can provide the smallest and shortest wood. Therefore, this semi-automatic lathe machine can be used in the process of producing sawn timber efficiently and rapidly as a product of the Nasom Village Community.
