FITTER - CITS

• 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.
