effects of tool length in milling operation

  • The Overhang Effect Modern Machine Shop

    The Overhang Effect The length by which the tool extends from the toolholder is a variable that can be used to tune the machining process. Contrary to what you may expect increasing the tool s L D ratio may reduce chatter and result in more productive milling.
