- 摘要:
- A toolholder with a controllable critical angle, such as a lead, trailing, rake or clearance angles, includes a tool spindle for retaining the toolholder in a tool rest of a machine tool. The machine tool includes at least one linear axis, for example, three mutually perpendicular axes, a rotary axis and a rotation axis. The rotary axis and/or rotation axis is controllable to move to a specified position in synchronization with a movement of one of the linear axes. An adaptor supports a cutting tool that is retained in the adaptor by a clamp. The cutting tool defines a critical angle, such as a lead angle, a trailing angle, a rake angle and a flank clearance angle, wherein the critical angle is corrected as a vector of movement of at least one of the linear axis is changed. In addition, the cutting tool can be positioned on opposite side of a centerline of rotation of the workpiece to effectively double the life of the cutting tool. A method of controlling a toolholder is also disclosed.
