DIAGRAM OF LATHE MACHINE. Explanation of the standard components of most lathes: • Bed: Usually made of cast iron. Provides a heavy rigid frame on which all the main components are mounted. • Ways: Inner and outer guide rails that are precision machined parallel to assure accuracy of movement.
Mar 18, 2017· Construction of Dynamometer Type Wattmeter: Following figure shows the dynamometer wattmeter for measuring the power. If two coils are connected such that, current proportional to the load voltage, flows through one coil and current proportional to the load current, flows through other coil, the meter can be calibrated directly in watts.
Repeat Drilling. With G81 drilling cycle drilling operation can be repeated multiple times. The drilling is repeated K times when that parameter is given with G81 drilling cycle. Repeat drilling is normally used with G91 Incremental mode, and a good example of repeated drilling is Gridplate drilling. the example for repeat drilling is given below.
Boring On a Lathe Single Point Thread Turning External threads can be cut with a die and internal threads can be cut with a tap. But for some diameters, no die or tap is available. In these cases, threads can be cut on a lathe. A special cutting tool should be used, typically witha 60 degree nose angle.
Mar 18, 2016· Sketch tip: How boolean operations work. Union: Merges two shapes into one. Subtract: Removes one shape from another. Intersect: Just shows the part where the shapes overlap. Difference: The area where the shapes don't meet is retained. The ones you will need the most are Union and Subtract, while the other two are not that common.
Carriage. The carriage holds the cutting tool and moves it longitudinally to the workpiece for turning operations or perpendicularly for facing operations. The carriage is composed of two castings: the top, or saddle, and the side, or apron.
Explain gang milling, straddle milling and string milling. Explain different operations carried out on a drilling machine. Differentiate clearly three jaw chuck with four jaw chuck. With neat sketch explain the importance of drilling, boring and reaming operation. Explain the procedure to prepare sand mould.
V (a) 1. Describe any two work holding device used in a turret lathe. 2. List any five differences between capstan and turret lathe. 3. state the differences between Jigs and fixtures. (b) 1. Explain the principles parts of capstan lathe with neat sketch. 2. Explain with neat sketches .
4. Draw neat figures wherever required. Attempt any TWO: a) State the different methods of taper turning used in lathe and explain anv with neat sketches. b) Explain ing lathe operations with neat sketches Eccentric Turning Knurling c) Classify the drilling machines and draw the neat sketch of Sensitive Drilling Machine. Attempt any TWO: a) b) c)
Q1 (a) With the help of neat sketch explain principal parts of lathe machine. [5] (b) Explain back gear arrangements with diagram for lathe machine. [5] Q2 (a) Enlist the different operation performed on drilling machine. [5] (b) Explain quick return mechanism of shaper machine with neat sketch. [5] OR
How is feed related to speed in the machining operations called turning? in turning, feed rate is the speed of the cutting tool along the work piece in the longitudinal (axial) direction. If the lathe carriage is driven independently of the spindle, there is no necessary relation between feed and cutting speed.
CNC G81 Drilling Cycle Program Example Fanuc G81 drilling cycle is used for simple drilling operations, so here is a cnc program example which demonstrates how G81 drilling cycle can .
b) Explain ing lathe operations with neat sketches Eccentric Turning Knurling c) Classify the drilling machines and draw the neat sketch of Sensitive Drilling Machine. Attempt any TWO: a) b) c) Draw the neat sketch of following tools and label them properly Twist Drill Reamer Differentiate between the Capstan Lathe and Turret Lathe and draw the block diagrams of each.
A lathe machine is generally used in metalworking, metal spinning, woodturning, and glassworking. The various operations that it can perform include the following: sanding, cutting, knurling, drilling, and deforming of tools that are employed in creating objects which have symmetry about the axis of rotation.
This may be done on a lathe or a milling machine. Boring is a machine operation in which the work is in contact with a single point tool. Get Price; sketch drawing milling machine . Sketch Drawing Milling Machine magentoadminsketch drawing milling machine sketch drawing milling machine. This is modeled by me with help from another project ...
Depth of cut is the distance that the tool bit moves into the work. usually measured in thouhs of an inch or in millimeters. General machine practice is to use a depth of cut up to five times the rate of feed, such as rough cutting stainless steel using a feed of inch per revolution and a depth of cut of inch. which would reduce the diameter by inch.
A canned cycle is a way of conveniently performing repetitive CNC machine operations. Canned cycles automate certain machining functions such as drilling, boring, threading, pocketing, etc... Canned cycles are so called because they allow a concise way to program a machine to produce a feature of a part. A canned cycle is also known as a fixed cycle. A canned cycle is usually permanently stored as a pre .
LATHE SPEEDS, FEEDS, AND DEPTH OF CUTS. General operations on the lathe include straight and shoulder turning, facing, grooving, parting, turning tapers, and cutting various screw threads. Before these operations can be done, a thorough knowledge of the variable factors of lathe speeds, feeds, and depth of cut must be understood.
Neat diagrams are the diagrams that are neatly made either on computer such as pie charts, histogram etc. or drawn with hands. These are easy to interpret and understand.
