How do you measure lathe speed?
lathe speed is numerically measured by cutting speed vdn/1000.
What is high speed machining?
It is the process of using high speed spindle rates and lighter passes to achieve rapid material removal.
How you calculate rated power of lathe machine?
It will be often desirable to know the power which is being consumed in operating a lathe on certain work for which data is required. For most purposes this can be sufficiently approximated by calculating the power of the lathe from the width of the belt and its speed in feet per minute. For such purposes it is usual among mechanical engineers to consider that a one-inch belt traveling a thousand feet per minute will transmit one horse-power. This will give us a key to the entire calculation.
When you are optimizing program operation which action provides the greatest speed increase?
Analysis.
Where does vibration occur most in a lathe machine?
Some major sources of lathe vibration are as follows: 1.) The stock you are turning is not centered properly, or has a lopsided mass. This has the same effect of to much clothes on one side of your wash machine during spin cycle. You can cure this by slowing down the speed you turn at until the roughed stock is more centered. 2.) Take a look at the head stock on your lathe, if it has worn bearings, if the pulleys are out of line or your belt is worn, you will most likely get vibration. 3.) Look at the floor your lathe is on. Is it solid? Cement is the best surface, an flex in your floor will result in lathe vibration. 4.) Look at the stand your lathe is on, is it solid, is it true. A level will let you know if youre base is sagging under the weight of your lathe. Make sure your lathe base is solid and not attached to surrounding walls. The common fixes: Bring your head stock and tailstock together until they touch. Do they line up perfectly, if not you may have a lathe base or floor that is sagging under the weight. Spin the lathe by hand. Is it smooth? If its rough or bumpy chances are you have worn bearings that need to be replaced. Use a straight edge to make sure all belts and pulleys are in line. Being off center will cause vibration or can cause un-even wear of the belts which in turn will cause vibration. If the belt is worn replace it. Add some weight to your base. The lathe is heavy so any vibration is sent right through your base and magnified. Add weight makes it harder for the lathe to move around and will decrease vibration of an out of round piece of stock.
