           Procedure

           Introduction
           1  We learn in theory call about blanking tool and blanking operation .
           2  Elements of blanking tool .

           For making something fist we need a sub material like that in a press tool wen we make a sheet in to cup 1st we
           need a blank means a sub material. And also blank us in many types of work so 1st step of work and at the time
           1st job is blanking tool.

             Procedure (DO)                    Information points/ safety precautions (Tell/Show)

                                 Blanking is a process of producing flat components. The entire periphery
              Introduction       is cut. The cutout piece is called blank or stamping. The tool used is called blanking tool.
                                 Ex. Washers
                                •  Introduce the material to be used for the blanking tool, discussing its properties and
            Material Selection    suitability for the application.
            and Preparation     •  Show examples of different materials and explain their advantages and limitations.
                                •  Demonstrate how to prepare the material for machining, including cutting it to the
                                  required size.
                                •  Set up the material on the lathe machine and secure it in place using appropriate
                                  clamping methods.
                                •   Use cutting tools to turn the material to the desired diameter and length according to
            Turning on Lathe      the tool specifications.
            Machine             •   Perform  facing  cuts  to  ensure  the  ends  are  flat  and  perpendicular  to  the  axis  of
                                  rotation.
                                •  Use turning operations to remove excess material and achieve the desired outer
                                  diameter and length of the blanking tool.
