This paper reports a statistical analysis of the laser wood cutting process. The laser cutting of wood is a multi-factor process and correct combination of the parameters involved is needed to achieve high quality and optimum process efficiency. In this paper a design of experiments and statistical modelling approach is used to investigate the significant process parameters by consideration of ...

Pressure techniques were used to remove 83 blades from a preformed obsidian core weighing 820 grams, yielding 17.32 meters of acute cutting edge. The blades represented 91 percent of the original weight (2.1 centimeters of acute cutting edge per gram of original material), thus demonstrating the efficiency of the pressure-blade techniques for the production of acute cutting edges.

Turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. In order to obtain desired surface quality by machining, pr...

the objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (dm yield) and 5 quality traits such as dry matter digestibility (dmd%), water soluble carbohydrates (wsc%), crude protein (cp%), acid detergent fibre (adf%) and total ash in tall wheatgrass (agropyron elongatum). in th...
