Abstract
This disclosure relates to a tool guide for a tool that shapes a workpiece. The tool guide may include a body having a contact surface configured to contact a surface of a workpiece, a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece, a guide element attached to the body configured to engage a surface feature of the workpiece, and an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.
Claims20
A tool guide for a tool that shapes a workpiece, the tool guide comprising:
- a body having a contact surface configured to contact a surface of a workpiece;
- a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece;
- a guide element attached to the body configured to slidably engage a surface feature of the workpiece;
- and
- an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.
A tool guide for a tool that shapes a workpiece, the tool guide comprising:
- a body having a contact surface configured to contact a surface of a workpiece;
- a positioning element attached to the body configured to removably engage a surface feature of the workpiece;
- and
- an upper opening and a lower opening in the body configured to limit the movement of a machining tool having a tool bit to a predetermined area, and configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.
A tool guide for a tool that shapes a workpiece, the tool guide comprising:
- a body having a contact surface configured to contact a surface of the workpiece;
- a first positioning element attached to the body configured to removably engage a surface feature of the workpiece;
- a second positioning element attached to the body configured to removably engage a second surface feature of the workpiece;
- an upper opening and a lower opening in the body configured to limit the movement of a machining tool having a tool bit to a predetermined area, and configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece;
- and
- a liner positioned within the lower opening wherein the liner includes a liner material having greater resistance to wear than the body,
- wherein the contact surface and the positioning element are each shaped to substantially conform to a predetermined portion of the workpiece.
