Abstract: A study was conducted to test the effects of three different speeds of 1830, 2066 and 2440 rpm of a mower knife with serrated edges and two different feeding angles of 45 ° and 90° on the pulverization of sweet potato vines. The results indicated that all the treatments were significant at 99% significance level for the pulverized percentage of sweet potato vines remaining on the sieve. The best result was for the 45° feeding angle with lowest vine pulverized percentage of 47.20%. The second speed of 2066 rpm had the finest vine pulverized percentage of 57.47%. The best performance for overlapping effect between feeding angle and speed of mower was achieved by the 45° feeding angle and a mower speed of 1830 rpm resulting in an average percentage of 44.45 % of pulverized vines.

Abstract: The effects of a rotary slasher with two different shapes of knives (L and Y-shaped) at three cutting speeds (1830, 2066 and 2044 rpm) were studied on percentage of pulverization of sweet potato vine passing through the sieve ( 28 mm 2 ). The results showed that all the treatments were significant at p 0.05 and p 0.01 significance level. The best result was by Y-shaped knife with highest vine pulverized percentage of 82.76 % and a mower speed of 2440 rpm had the finest vine pulverized percentage of 90.48 %. The best performance for interaction effects between knife shapes and speeds of mower was achieved by the Y-shaped knife and a mower speed of 2440 rpm resulting in an average percentage of 92.62 % of pulverized vine.

Abstract: Two different shapes of knives (L and Y-shaped) for the rotary slasher with 300 knife cutting angle at three cutting speeds (1830, 2066 and 2044 rpm) were used to indicate their effects on the power consumption for pulverizing sweet potato vine which passed through the sieve ( 28 mm 2 ). The results indicated that all the treatments were significant at p 0.01 significance level for the power consumption on sweet potato vine pulverizing. The best result was recorded from L-shaped knife with a power consumption of 52.12 Watts for sweet potato vine pulverization. Meanwhile, the best result was for the mower speed at 1830 rpm with the lowest power consumption of 61.23 Watts. The best performance for interaction between knife shapes and the cutting speeds was achieved by the L-shaped knife at 1830 rpm with lowest power consumption of 50.23 Watts at p 0.01.

Abstract: The development and application of Titanium Aluminium Nitrate (TiAlN) coatings for cutting tools has led to dramatic tool life extension and the realisation of high speed machining for hardened materials. This results in longer tool life and makes it possible to employ higher cutting speeds and feed rates. In this study, a series of different TiAlN based coatings on micro grains solid carbides were tested on H13 Tool Steel. These advanced coatings are commercially available by coating manufacturer which are trade marks of Balzers UK. The aim of this experiment was to investigate the performance of micro tools coated with these coatings and compare with uncoated tools. The results will be used to determine whether coatings for micro tools will have any impact on the performance of the tools such as reducing cutting forces or improving machining quality. This will be achieved by means of analysing the cutting force data and 3-D surface roughness respectively. Result obtained shows that different coating had different performance, hence can be applied to specifically targeted machining operation. The results also highlight some of the differences in wear mechanism of micro tools.

Abstract: In this study, solidification analysis of metal matrix composite, aluminium-11.8% silicon alloy matrix reinforced with titanium carbide particulates is performed. Sand casting method is used as the manufacturing method to produce the specimens. Thermal measurements during the casting process are captured and solidification graphs are plotted to represent the solidification characteristic. Solidification analysis is performed by interpreting the solidification graphs. Parameters such as the nucleation of primary alpha phase temperature, liquidus arrest temperature, liquidus undercooling, eutectic growth temperature and solidification time are presented. The results show that introduction of second phase particulates into a matrix alloy have affected the various time and temperature parameters of its solidification properties.
