Actually, there are 2 classifications of turning operations...
It can be classified as External operations and internal operations.
In external operations are:
1. Turning-(including steps, tapers, contours, and chamfers)
2. Facing
3.Grooving
4. Cut-off-(also called parting)
5. Thread cutting-(also called screw cutting)
while in Internal operations are:
1. internal drilling
2. Boring
3.Reaming
4.Tapping-(internal thread cutting)

EzraTurning between centers on a lathe entails turning a workpiece between centers located in both the spindle and tail stock. This operation eliminates any inaccuracy from the effect of a possible inaccurate or worn chuck.
To achieve this, the chuck is removed and a backing plate with a drive pin is installed in its place. A dead center is set into the spindle and a live center into the tail stock. A lathe dog or carrier is clamped around the workpiece towards the end nearest to the spindle. The workpiece is then set between the centers with the carrier resting against the drive pin.
Drive centers for metal working have almost eliminated the use of the carrier/pin method. Instead of the backing plate, carrier and dead center, a drive center is set into the spindle. It drives the workpiece by setting its crown into its face and allows machining over the entire length of the workpiece in single cuts. Using a drive center is also considered "turning between centers".
Centering a work piece usually refers to when the piece is put into the chuck and the end faced off and then centre drilled to provide small tapered hole which can then accommodate and be supported by a running centre in the tailstock. In the case of a work piece being held in a four jaw chuck, centering would refer to adjusting each jaw to get the work piece running in the desired axis.

What is the meaning of operation in lathe machining?
An "operation" is one step in a manufacturing process. Typically, there are a number of operations required to manufacture any given part, and you try to do as many of them in a single machine setup as possible to save time and cost. Considering lathework, you might have a part that requires this set of steps to make: 1. Rough turn stock / 2. Final turn outside diameter. / 3. Turn snap ring groove / 4. Turn thread undercut / 5. Cut thread / 6. Knurl / 7. Face / 8. Cutoff Each of these steps would probably use a different cutting tool in the lathe, and would be an operation. Depending on the sophistication of the lathe, all the required tools might be loaded into a turret in the sequence they are required. That would be the setup.
Which conditions are used in step up transformer?
Transformers, step up or step down, use mutual induction in their operation.
What is the programming language that is one step above the machine language?
we can say c,c++ also.. but not sure..
What Programming language is one step above machine language?
I guess you're trying to refer to Assembly language.
When will There be a time machine invented?
there was already time michines invented but we can remake them bye things step one:GET THE THING STEP TWO: PUT IT IN THE DIRT STEP THREE: WAIT A COUPLE DAYS IF THIS DOENST WORK I HAVE MORE BUT I WONT BE TODAY I HAVE OTHER ANSWERS TO OTHER QUESTIONS TO CATCH YA LATER PC OUT HATERS ok
