Machining:  Sintered parts do have some porosity and it is, therefore, necessary to differentiate their machining behaviour from those of fully dense wrought products. The major differences are, as follows: (i) when a porous metal is machined, the depth of work hardening is more important than for the wrought metal, as in case of former, pores create stress concentration. (ii) The temperature at the tool end causes oxidation of the ...

DESIGN OF MELON DE-HUSKING AND SEPARATION MACHINE

 INTRODUCTION Nigeria is an agricultural nation. Melon (Citrullus Vulgaris) is widely cultivated in Nigeria, among other seedlings during the planting season yearly. Several tones of the melon seeds are gathered each harvesting period but only very low percentage of the total harvest are dried by atmospheric draught and bagged for storage. High percentage waste is encored due to lack of good processing and storage facilities.Melon when properly processed yields a lot of by-products, whic...
