EXERCISE 68 : Preparation of simple press tool & try out
of component
Objectives
At the end of this exercise you shall be able to
• demonstrate the step-by-step process of manufacturing a blanking tool
• demonstrate the step-by-step process of manufacturing a blanking tool
• deburring on raw materials by filling
• Lathe operation - facing & turning
• milling operation using vertical milling
• surface grinding and assembly of blanking tool.
Requirements
Tools/Instruments
• Try square • Milling machine
• verniers caliper • Grinding machine
• verniers hight gauge • Drill press Cutting tools (end mills, drills, taps)
• Files • Materials (tool steel, carbide inserts, etc.)
• Lathe machine • Safety gear (goggles, gloves, ear protection)
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.
