Abstract
A cutting tool holder assembly comprises a body having a shaft non-rotatably mounted therein for axial movement to enable adjustment of a cutting tool on a cutting tool holder member carried by the shaft. Strain gauge elements are mounted on a blade which is arranged to be deflected upon relative movement between the shaft and the body. The strain gauge elements produce an output signal proportional to the deflection of the blade.
Claims11
A cutting tool holder assembly comprising a body, a shaft mounted in said body for axial movement relative thereto, a cutting tool holder member carried by said shaft externally of said body, means for preventing rotation of said shaft relative to said body, moving means for moving said shaft axially relative to said body to enable adjustment of a cutting tool carried by said cutting tool holder member in use, and indicating means for indicating the position of the shaft relative to the body, wherein said indicating means comprises at least one strain gauge element, mounted on a deflectable member which is arranged to be deflected upon relative movement between said shaft and said body, and wherein said indicating means is adapted to produce an output signal proportional to the deflection of said deflectable member.
A cutting tool holder assembly comprising a body, a shaft mounted in said body for axial movement relative thereto, a cutting tool holder member carried by said shaft externally of said body, a rotation prevention arrangement disposed between said shaft and said body, an adjustor to provide movement of said shaft axially relative to said body for adjustment of a cutting tool carried by said cutting tool holder member in use, and an indicator for indicating the position of the shaft relative to the body, wherein said indicator comprises at least one strain gauge element mounted on a deflectable member which is arranged to be deflected upon relative movement between said shaft and said body, and wherein said indicator is adapted to produce an output signal proportional to the deflection of said deflectable member.
