This study proposes a new way to accurately measure transient cutting forces of a rotating tool such as a milling cutter from the tool side. The transmission of cutting forces through mercury slip ring or FM antenna is liable to be affected by noises. Therefore, a noise-free device has been developed to obtain reliable cutting data, where amplified output signals from strain gauge bridges are digitized using a 8-bit A-D converter and then converted to continuous serial data streams to optically transmit them outside a machine tool by use of LED. Received serial data streams are conversely restored to parallel data, which are immediately plotted under the control of a personal computer. The transient cutting forces can be measured without any trouble., As a result, this method was found to be very practical to analyze cutting phenomena and applicable to a variety of measuring field.
