WRITE A PART PROGRAM FOR LATHE OPERATION (Circular Interpolation).

Read the passage and answer the following questions WITH NO MORE THAN THREE WORDS OR A NUMBER.HOW TO USE A LATHE MACHINE?Basically, a lathe machine is a tool used to shape metals. The material is rotated in the cylindrical motion and then touches a cutting tool to it which cuts the material. The metal sheet is fixed on the chuck of the lathe machine and then the chuck rotates in the vertical direction as well as right and left direction and touching byte’s tip to the material to cut the metal. The original lathe machine when invented used to complete tasks like cutting cylindrical metal sheets and then it was further developed to produce screw threads, tapered work, drilled holes, knurled surfaces, and crankshafts. The modern lathe machines available nowadays, offer the facility of rotating speeds as well as adjusting manually and automatically the cutting tool. There are different types available like light duty, medium duty, heavy duty, extra heavy duty, all geared, imported, CNC, roll turning and many more. No matter what type it is, you need to follow the below given basic instructions while using it.You need to ensure that it should not be started cold. First of all, warm up the lathe machine for 10 minutes, setting its speed up to 1000 rpm. It should also be well lubricated and you need to check all the tools and ensure that they are tight.Now, the tool holder should be located and tool block should be inserted in it. The spot is supposed to be located in the tool block where you can insert a cutter. Also for safety reasons, you need to tighter the tool block as tighter as you can. The cutters allow the users to cut from left to right, which is also known as cutting on a Z axis.The tail stock is to be located where drill chuck can be inserted. The tail stock is very useful as it helps in drilling holes in the metal. The crank at the end of the measuring device helps in performing precision depths to the cuts.The next step would be to set your zero and stop the turning spindle. You need to get a tool holder and put in at least 0.5 inch block between the tip of your tool and the metal sheet. Slide the tool holder in and out on an X axis to tighten it. The micrometer wheel should be set to zero.Also you need to set your X zero point by pulling the Z axis tool towards the spindle and slide 0.5 inch block between the tool and the work piece. You also need to set the X axis micrometer to zero and turn the wheel 0.5 inch away.So, now if you want to cut 0.5 inches from the metal sheet keep X axis and Z axis both 0.25 inches away from the metal sheet and then start the spindle.How many uses does a modern lathe machine offer? How long does it take to heat the lathe machine? What allows the users to cut from left to right? What is needed to drill holes in the metal? What is the distance between the tip of the tool and the metal sheet?

Read the passage and fill in the blanks WITH NO MORE THAN THREE WORDS AND/ OR NUMBERSA metal lathe machine is a lathe that is designed to shape hard materials. When you buy a new lathe go through the instruction manual very carefully. These manuals are quite easy to follow. Even on the internet a lot of information is available regarding the usage of this equipment.Tips to follow while using a Metal Lathe Machine:A metal lathe is not a small so for the first few days work under an experienced metal worker and take his guidance. If you are not careful it can lead to injury.Warm up the machine for about 10 minutes at a speed of 1000 rpm, never run the device cold. It should be well lubricated.Check and prepare the tools and make sure they are tightly placed. Insert the tool block in the tool holder, insert the cutter and tightened it properly.Insert the drill chuck in the tail stock. This is used to drill holes in the metal piece. The crank is located at the end of the measuring tool.Wear protective eye equipment while working with metal or the splinters can damage your eyes. Keep the hair tied tightly.Wear gloves and other safety guards while using it. Wear tight fitting clothes; remove any jewelry or the tie.Support the device with a clamp or a holder, this reduces the strain on the lathe and prevents the cutting from chatter.Clean the center carefully before inserting it in the headstock or the tailstock.Once in a while open and clean the gear teeth of the accumulated fine particles of metals. Use pliers or a brush to remove chips of metal.Always stop the tool and then make adjustments and let it stop completely before changing spindle speed.Always take care to choose a good quality metal lathe machine, which is of superior class. One must be aware of the safety risks associated with using a metal lathe and understand the precautions in order to avoid accidents.When you buy a new metal lathe, you should read the very carefully.It would be well lubricated to warm up the lathe for about at a speed of 1000rpm.The drill chuck in the tail stock is used for drilling in the metal piece.The splinters can hurt your eyes if you don’t wear when working with metalYou need to understand the safety risks and to prevent form accidents.
