• Transfer the blanking tool to the milling machine and secure it in the vise or fixture.
• Set up the milling machine with the appropriate cutting tools, such as end mills and
Milling on Milling slot drills.
Machine
• Mill the flat surfaces and features of the blanking tool, such as the cutting edge and
mounting surfaces, to the required dimensions and tolerances.
• Use milling operations to create any slots or keyways necessary for tool assembly
or functionality.

• Set up the drill machine with the appropriate drill bits and tapping tools.
Drilling and • Drill holes for mounting screws or other fasteners as needed, ensuring proper
Tapping alignment and depth.
• Tap the holes to create threads for the fasteners, using the appropriate tap size and
lubrication to ensure smooth threading.
• Use a grinding wheel or abrasive belt to refine the cutting edge of the blanking tool,
Grinding on ensuring sharpness and precision.
Grinding Machine • Perform any necessary grinding to achieve the desired surface finish on critical
surfaces of the tool.

• Assemble the various components of the blanking tool, such as the punch and die,
if applicable.
Assembly and • Ensure all components are properly aligned and secured, using fasteners or
Quality Check adhesives as necessary.

• Verify that all assembly operations are performed accurately and according to the
tool specifications.

• Always wear appropriate personal protective equipment (PPE) when working with
machinery and tools. Additionally, wear close-toed shoes with non-slip soles to
Machine And prevent slips, trips, and falls.
Personal Safety • Ensure that all machine safety guards and barriers are in place and functioning
correctly before operating any machinery. Never remove or bypass machine guards
unless necessary for maintenance or repair, and always follow proper lockout/tagout
procedures when servicing machinery

Imitation (Application)

a For making washers in industries on mass production.
b Required size and shapes blank for depend on work.
Summary : Making a blanking tool involves selecting high-quality materials, machining them to the desired
shape and dimensions using lathes, milling machines, and grinders, assembling the components, and conducting
quality control checks to ensure precision and accuracy. Following safety protocols and continuous improvement
practices are essential throughout the process.

Practice / Evaluation (Test)
a Master in a lathe, milling and grinding for make workpiece in more accuracy.
b Calculate clearance between punch and die.
