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)
Turning 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.
A quote from the related link is "Most lathe centers have a tapered point with a 60° included angle to fit workpiece holes with the same angle. ". I am a Mechanical Engineer and I have never seen an angle other than 60 degrees for the lathe center.
Step turning is an operation performed on lathe machine where the excess material is removed from the workpiece to obtain various steps of different diameters.
step turning is basically an operation performed on lathe machine to reduce diameter of a cylindrical work piece
Moving parallel to the longitudinal axis of the workpiece the tool is called the x-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
Your lathe is not cutting correct screw pitch?
1 - You can control the angle of the screw cutting tools. 2 - setting screw cutting lathe control. 3 - reduce the depth at every step. 4 - Adjust the speed milling machine. 5 - Barry screws to release the lever, do not screw cutting lathe.
How does one use a woodturning lathe?
(Please note - the folllowing explanation is for wood latt NOT lathe) A piece of wood, fairly flexible, usually about two inches wide and about a 1/4 to 1/2 inch thick and as long as necessary. It is used for lattice work and is often found as a base for plaster walls in older homes.Wooden table legs are turned ona wood lathe - the wood lathe is used to make a square pole of wood round.How a wood lathe worksWood Lathe Basically, a small engine, usually electric, turns a set of gears. These gears are connected to more gears via a V belt (a loop of rubber, tightly on the two gears).The turning of the gears turns the lathe.Depending on what you are lathing, the actual setup of the cutting instruments varies. The best way to find out how to use a lathe is to go and take a course at TAFE.A lathe , as you most likely know, is a machine that spins a peice of wood at a high (or low ,depending on what you are carving) velocity. It consists a motor, tool rest, and peices of metal to hold the wood in place. The peices of metal used to lock the wood into place vary, depending on how it needs to be held. You use a chisle, (once again, different variaties of chisles) to carve the wood while it is spinning.
How can you produce a multi-threaded screw using a lathe machine?
If you want to screw with a track with two step 2 millimeters must build orderly winding Berry lathe on 4 millimeters step and then you made the turn 4 with step without States' the orderly winding change or turn lever Berry free Upper slide as much as 2 millimeters to move on the front and back screw Berry.

What steps tomake acustomer's nolonger working machine to work again?
Step 1: Receive non-working machine from customer. Step 2: Charge customer a diagnostic fee. Step 3: Examine machine to determine why it doesn't work. Step 4: Go out and buy parts to fix the machine, if parts are called for. Step 5: Repair the machine. Step 6: Call the customer and have her pick the machine up. Step 7: Collect the repair fees from the customer and deliver the machine to her. I can't be more specific than that because it depends on what the machine is and why it's not working. The steps to cure "dryer won't heat up" are radically different from "bulldozer will not start."
