this year one of my subject is Amalan Kejuruteraan Mekanikal III...but is very special tis year...we are given 4 choices to choose for...CADCAM/CNC , Loji , Bahan , Textile...CADCAM/CNC which is more to programming, Loji is study about aircon n piping system, Bahan is abt moulding and for Textile is cloth(not sure)..
so i choose CADCAM/CNC...tis subject is about prepare program or type our own program then install d program we typed into machine..then d machine will run the program n cut d workpiece...is separated into 3parts: Milling , Turning(Lathe) n CADCAM(i not sure about tis coz i not yet take it)....Basically, tis subject is to reduce d burden of man...if u a regular visitor of my blog since last year, u sure read one of my post about my Amalan Kejuruteraan Mekanikal I(AKM I)...if not, then im briefly explain about it bah....
in AKM I, Lathe n Milling were done by manual...we hv to cut the workpiece by our own hands and it take many time(if not wrong i think is about 3weeks..each week about 3hours...so u can calculate it)....n d project we made if not so nice...n we juz hv one chance only,if wrong cut then habis lah...d project contains many defects, surface not smooth,not shinny or even broken...through d process, oil(lubricant) will split everywhere n mostly kena ur clothes...very dirty,disgusting n sweating....one word to describe=>dirty....
but now since d technology getting better, machining is d most effective way to overcome these problems....we juz need to type a program according our drawing...type in the numbers n others to form a program...after tat,we juz use pendrive to transfer d program into machine...n press button....THATS ALL ! ! !
tis post will talk about Turning only...next time only talk abt Milling....
Alright...Lathe is a technique to produce a solid cylinder object by cutting...the workpiece is in solid cylinder shape which is mostly made my iron or aluminium or others aso hv....d machine will clamp d workpiece at the left hand side and turn itself at tat position...then d cutting tools will move at x-axis and y-axis only during cutting...through lathe,u can produce many n many n many cylinder shape of projects....about Lathe deeper detail information can check from internet since is convenient...haha....
we hv three weeks for do a turning(lathe) project tis time...1st week is lecture class only...teach us how we use use the program n wat we should type...then during 2nd week,we are given a drawing which hv our project drawing n reading in it...we follow the readings n type our program...then we take it to machine to process it...it only take us 7minutes n 47seconds....is amazing....! ! ! Clean n Tidy @.@
and FINALLY ! ! !
TaDaa~~~! ! !

this is the raw material....before it process...

After being processed....Its smooth n shinny....Feel proud of it...Still got Good Design Reward....haha....
