● Step 2
After wearing a ppe, I went to our lathe which is in side of a room
...
After turning on the machine, we have to check the emergency stop that it is
working or not

Task 4 M1
To manufacture a correct workpiece, it is important to carry out checks for accuracy of feature
on components during and after manufacture because if we didn’t check regularly we might end
up making the wrong ones with wrong measurement
...
They are:
To check for accuracy using measuring equipment:
All the secondary machine that we are talking turning, milling and drilling need the
component that they produce to be checked for accuracy
...

Micrometer:
Micrometer(Reference: hornady
...
They have
good accuracy of 0
...
Some types have an accuracy of 0
...
Lots of practice and
skills needed to use micrometer to get a correct accuracy
