A lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, or deformation. Lathes are used in woodturning, metalworking, metal spinning, and glassworking. Lathes can be manually operated or CNC (computer numerical control) operated.
In a lathe machine lab report, the goal is to document the results of using the lathe to perform various machining operations. The report should include a brief introduction to the lathe and its parts, a description of the workpiece and the machining operations performed, and a discussion of the results.
The introduction should provide some background information on the lathe and its parts, including the headstock, tailstock, bed, and carriage. The headstock is the stationary part of the lathe that houses the motor and drive system. The tailstock is a movable support that can be positioned along the bed to hold the workpiece in place. The bed is the base of the lathe that supports the headstock and tailstock, and the carriage is a movable platform that carries the cutting tool.
Next, the report should describe the workpiece and the machining operations performed. This might include information on the material, size, and shape of the workpiece, as well as the specific cutting tools and techniques used. For example, the report might detail the use of a lathe to turn a cylindrical piece of metal, or to drill a hole in a wooden dowel.
Finally, the report should include a discussion of the results of the machining operations. This might include a description of the surface finish achieved, the accuracy of the cuts, and any problems or challenges encountered during the process. The discussion should also include any modifications or adjustments made to the lathe or the machining process in order to improve the results.
Overall, a lathe machine lab report is a detailed documentation of the machining operations performed using a lathe, including a description of the lathe and its parts, the workpiece and the machining operations, and the results of the machining. By carefully documenting the process, the report can serve as a valuable reference for future machining projects and help identify areas for improvement.
The basic lathe that was designed to cut cylindrical metal stock has been developed further to produce screw threads, tapered work, drilled holes, knurled surfaces and crackshafts. My four year academic curriculum in Mechanical Engineering at Pune University has offered me the perfect blend Bucknell University Personal Statement from material property characterization, flow loop, and performance testing of vacuum cleaners. Always wears appropriate and suitable clothes during a workshop practical work. BoringBoring is enlarging an existing hole. Cutting tool touch the edges 0.
The program may be modified and displayed at the machine, along with a simulated view of the process. The heavy duty lathe machine has dimensional accuracy due to which it ensures high tensile strength and longer service life. Moreover, heavy duty lathe machines are quite easy to install and operate. Cutting fluid may also be pumped to the cutting site to provide cooling, lubrication and clearing of swarf from the workpiece. In this variety of turning machines, the main components that enable the work piece to be rotated and the cutting tool to be fed into the work piece remain the same. Now, I am able to operate the lathe machine with more proficient and confident. Lathe Machine Parts Bed — mainly support the whole machine.
This operation is called facing. Lathes can be used to shape pottery, the most well known design being the potter's wheel. Used to hold long workpiece in place or mount a drill chuck for drilling operation. The Romans improved the Egyptian design with the addition of a turning bow. The denture is not initially made out of acrylic. Adjusting knurling tool to workpiece.
Independent Chuck - 4 Jaw This is independent chuck generally has four jaws, which are adjusted individually on the chuck face by means of adjusting screws. This type of lathe machine is designed for performing many tasks efficiently like screw cutting, sliding and surfacing operations. The measurement of the workpiece must be taken from time to time to ensure that the dimension of the project is precise and accurate. Do not wander around the workshop, or distract and interfere with other students work. Since the front end of the work piece is also uneven, it needs to be leveled by facing cut the end of the workpiece. Make sure all of the machines in the workshop have a good grounding before start using them.
Shape of workpiece after finished turning the front part. Drilling operation requires a higher speed while knurling operation requires a slower rotation speed. Listen and follow carefully to the instructions from the lecturer. Level the end and reduce overall length of workpiece 9The diameter of the front part of the project is then reduced to 25 mm with the length of 30 mm. Last but not least, the lecturers have explained and demonstrated to us the operations that can be done with a lathe machine such as facing, turning, taper turning, drilling and knurling. Halfnut lever a lever to engage the carriagewith leadscrew to move the carriage under power.
Hot and sharp fragments of workpiece may be directly sent flying over to your eyes. Im able to apply all the safety procedures while operating lathe and grinding machine to avoids accidents from happening. Ornamental lathes can produce three-dimensional solids of incredible complexity. The lathe machines are made of the gearbox, headstock, carriage, toll stock, and the bed. Metal Spinning Lathe Metal spinning, also known asspin formingorspinningormetal turningmost commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetricpart. In addition, I trained new graduate lab assistants; developed two new lab modules addressing industrial safety for operating lathes, drill presses, and milling machines; and developed a presentation on the technical writing skills required for the content and format of the lab reports. Know all the operations using lathe machine and how to execute them.

Given the advent of high speed, high pressure, industrial die forming, metal spinning is less common now than it once was. The work piece is placed in the lathe chuck and will be spinning while the boring tool is slowly driven into the opening. Lathe Introduction In woodturning, metalworking, metal spinning, and glassworking, a lathe is a machine tool which spins a block of material so that when abrasive, cutting, or deformation tools are applied to the block, it can be shaped to produce an object which has symmetry about an axis of rotation. FacingFacing is when you remove wood or metal from a cylindrical work piece. The carriage need to be push to the left slowly. When a workpiece is supported at both ends, it is more stable, and more force may be applied to the workpiece, via tools, at a right angle to the axis of rotation, without fear that the workpiece may break loose. With this set-up, machining is done more efficiently.
The machine is controlled electronically via a computer menu style interface. . The lecturer also explained about the safety precautions that have to be followed when taking a measurement so that the reading of an object will be precise and accurate. Other designs have been used, e. For 20mm diameter cut,we need to repeat 4 times because to follow the safe operation procedure. A cylindrical metal with the diameter of 40 mm and 83 mm long is cut out from the originally long cylindrical metal by using the horizontal band saw machine. In some modern lathes this power source is an integral electric motor, often either in the headstock, to the left of the headstock, or beneath the headstock, concealed in the stand.
Hole on the centre of workpiece 13 Adjust the ball bearing live center to fit in the hole and hold the front part of workpiece for knurling operation. However, if you use a chuck you can face rectangular, square or other unusual-shaped pieces. The work piece is then clamped to the faceplate, typically using t-nuts in slots in the faceplate, or less commonly threaded holes in the faceplate itself. The turning process requires a turning machine or lathe, work piece, fixture, and cutting tool. A string is passed through the two pulleys on either side of middle section and the pulley at Personal Statement For My Masters In Mechanical Engineering of mechanical engineering those are applicable to most of the machines, tools and processes which naturally widens my scope of learning and research. Knurling the centre part of workpiece 6. Glassworking lathes Glassworking lathes are similar in design to other lathes, but differ markedly in how the workpiece is modified.
