which statement below is the correct way of leaving the milling machine after an operation
Leave everything where it is as it may be useful for the next job.
Clean all tooling, measuring equipment, and work holding devices then return them to their designated stores. Remove swarf from the bed of the machine and the surrounding area and dispose into the appropriate bin.
Clean all tooling, measuring equipment, and work holding devices then return them to their designated stores. Immediately start the set-up of the next job without cleaning the mill.
Take everything back to the store the way it is as it is the store persons job to ensure its clean and safe to use.
to work out the appropriate feeds and speeds for the milling machine, the correct formula is
RPM=π×ϕ(cutting speed×1000)
RPM=π×2d(cutting speed ×50)
RPM =a2+c2b2
RPM= −b±2ab2−4ac
this type of fit is
skin tight
transition
interference
clearance

which type of cutter would best suit milling a large plane surface with minimal vibration
opposing helical slab mill
end mill
slot drill
bull nose tungsten carbide tip tool
when using a dividing head you need to rotate the component 30 deg. calculate the number of full turns and holes needed to create the angle (40:1 ratio with a plate that has 21, 23, 27, 29, 31 & 33 hole rings)
3 turns 5 holes in a 23 hole plate
3 turn only
3 turns 7 holes in a 21 hole plate
3 turns 31 holes in a 33 hole plate
