Ohno repeats Taylor. Examine every element of operation/process to increase productivity.
"We have eliminated waste by examining available resources, rearranging machines, improving machining processes, installing autonomous systems, improving tools, analyzing transportation methods and optimizing the materials at hand for manufacturing. High production efficiency has also been maintained by preventing the recurrence of defective products, operational mistakes, and accidents, and by incorporating workers' ideas." Taiichi Ohno (P. 21)

1 - Roughing the outer diameter
Your Challenge:
Maintaining efficiency through effective chipbreaking when roughing the outer diameter.
Solution: Jetstream Tooling delivers a high-pressure jet of coolant to the optimum position close to the cutting edge. In addition to eliminating heat build up, this lifts the chip away from the rake face to increase chip control and maximize tool life. Cutting parameters can also be further increased by using ISO/ANSI Duratomic® inserts. Benefits delivered include increased process reliability and productivity
