WHEN THE FIRST INDUSTRIAL REVOLUTION took place all those years ago, ‘economies of large scale’ was the obvious benefit that everyone was looking for. Years later, the same logic applies when one looks at the phenomenon of High-speed Machining (HSM) that has impacted modern-day machining requirements. These economies not only come directly from costs saved in large-size batch manufacturing, but also through productivity improvements and waste reduction, in addition to improved quality and longevity of machine tools used for such operations. In essence, HSM can well be termed the product of the 21st century industrial revolution. In simplest terms, high-speed machining allows machining of materials at 4-5 times of the conventional speed without compromising on quality or material removal rate.

As a keen user of such machines, M S Shankar, VP, manufacturing operations, centre of excellence for engine manufacturing, VE Commercial Vehicles, describes the benefits of HSM. He says, “HSM technology helps reduce the overall number of equipment needed to deliver the total volume while retaining the flexibility. On the HSM, one can quickly leverage innovations in cutting tool material and geometries. Improved rigidity and higher power available in contemporary high-speed machines enable faster metal removal.”

He adds, “The advantages of HSM include the requirement of a relatively lesser foot print, thereby enabling savings on overall shop floor size, provision of a consistent quality, savings through lower setup change costs and, most importantly, allowing flexibility.”
