                           •   If the drawing tool consists of multiple components, assemble them carefully, ensuring
             Assembly        proper alignment and functionality.
                           •  Use fasteners, adhesives, or welding techniques as necessary to secure the components
                             together.

           Personal Protective Equipment (PPE):

           •  Require all personnel to wear appropriate PPE, including safety glasses, ear protection, steel-toed shoes, and
              gloves, to protect against potential hazards such as flying debris, loud noises, and sharp edges.
           Machine Safety:

           •   Ensure that all machinery and equipment are properly guarded and maintained according to manufacturer
              specifications to prevent accidents caused by moving parts, sharp tools, or electrical hazards.
           •   Conduct  regular  inspections  of  machinery  and  equipment  to  identify  and  address  any  safety  hazards  or
              malfunctions promptly. Tool Handling:
           •   Train  personnel  on  the  safe  handling  and  use  of  cutting  tools,  including  proper  lifting  techniques,  secure
              storage practices, and correct handling procedures to minimize the risk of injury from sharp edges or heavy
              components.
           (Application)
           a  Make flat blank into a cup shape by drawing operation.

           b  Make cylindrical cups by drawing operation for mass production.
           Summary : How to make a Drawing tool and required materials selection and raw material cutting
           Machine Machining the raw material and make them part of press tool and assembly of perforating tool. and
           personal safety precautions.

           Practice / Evaluation (Test)
           a  Use machine scale and reading of scale for making job in more accuracy.
           b  Follow safety precautions on doing work.
           Next skill : Curling Tool.



           Making a Drawing Tool (Punch & Die)

           Objectives : At the end of this exercise you shall be able to
           •  able to select materials for Tool
           •  able to Machining Operation on Tool (workpiece)
           •  able to heat treatment on required parts of Tool
           •  able to assemble tool part of tool
           •  know about safety precautions.

           Procedure

           Design Phase:
           •   Gather requirements from stakeholders regarding the dimensions, materials, and production volume of the
              final product.
           •  Conduct feasibility studies and risk assessments to ensure the proposed design is viable for manufacturing.
           •  Utilize Computer-Aided Design (CAD) software to create detailed 2D and 3D models of the drawing tool,
              considering factors such as geometry, material properties, and tolerance requirements.
           •  Perform finite element analysis (FEA) simulations to predict the tool’s performance under various loading
              conditions and identify potential areas of weakness.
