Problem Statement

• Research Current Production Processes
• Analyze materials currently used and research
  possible alternatives
• Optimize manufacturing time and cost
  effectiveness
• Present an acceptable proposal to improve product
  and manufacturing processes

3
Current State of the Art

• Simple Blades
• High Speed Steel
• Dye Cut
• Complex Blades
• Laser Cutting for Rockwell Hardness (ex. 40-45)
• Dye Cutting for Medium Hardness Steel (ex. 30)
• Complex Metal Brazing
• Blade Core in Tension
• Teflon/Chrome/Painted Coatings

Current State of the Art
The manufacturing of circular saw blades starts
with sheets of steel.
5
The raw sheets are passed through a machine and
checked by hand to insure flatness
6
Current state of the art facilities use a laser
in place of stamping to create the center hole
for the blade.
The steel fragments are washed away
7
Blades are then heat treated to strengthen the
steel.
Tension rings are then inserted inside the blades
to keep the material in compression.
8
Large carbide tips are installed and brazed
electronically
The saw blades are then sand blasted for a mirror
finish
9
The carbide teeth are then ground to their
specific geometry
The saw blades are then etched with safety
information, logo, and labels for the consumers

Improvement Goals

• Produce Saw blades that last longer, cut better,
  and are more cost effective
• Eliminate waste in the manufacturing process
• Research ways to utilize different materials to
  make a better saw blade
