NC milling using Mazak Vertical Machining Center AJV 25/405

CNC milling using Mazak Vertical Machining Center AJV 25/405

the project is to visit a manufacturing facility and analyze making 3 different parts using three different processes

one of these part is Peerless pumps used in Commercial Fire suppression systems and it is made using CNC Milling machine(Mazak Vertical Machining Center AJV 25/405)

I want 750 words comprehensive narrative describing the manufacturing process (Milling) observed during the transformation of raw materials to finish state of the part, discussing
vertical mill,
the milling process,
what to consider while milling,
why cutting fluid is used while milling,
and try to connect these points to making the part using the vertical mill including the pictures

the part raw material is (Pre-treated SAE 4140 ) and it was finished in two phases :
phase one: the front edge was milled with a curve in it and it took 15 min to finish this process
phase two: without changing the orientation of the part the middle part was milled using different milling cutter and it took 15 min to finish this phase

I will include a file that has all the pictures you need to explain making the part using vertical milling process
please refer to the figures in the discussion

if you have any question let me know
