Abstract
A hybrid cutting apparatus and a method of cutting a groove are provided. The hybrid cutting apparatus includes: a main body that is connected with a rotation shaft of a machine tool; a grooving tool that is coupled to one side of the main body and for forming a groove at an interior circumference of a workpiece; and a tool position control means that controls a position of the grooving tool to correspond to a cutting surface position of the workpiece.
Claims17
A hybrid cutting apparatus, comprising:
- a main body that is connected with a rotation shaft of a machine tool;
- a grooving tool that is coupled to one side of the main body and for forming a groove at an interior circumference of a workpiece;
- and
- a tool position control means that controls a position of the grooving tool to correspond to a cutting surface position of the workpiece,
- wherein the tool position control means comprises a moving unit that moves a grooving tool such that a cutting tip of the grooving tool arrives at a groove processing depth of the workpiece, and
- wherein the tool position control means further comprises:
- a distance sensor for measuring a distance between a cutting tip of the grooving tool and the workpiece cutting surface;
- and
- a control unit that automatically controls a level in which the moving unit moves the grooving tool according to a value that is measured by the distance sensor.
A method of cutting a groove at a cylinder bore surface using the hybrid cutting apparatus, the hybrid cutting apparatus comprising:
- a main body that is connected with a rotation shaft of a machine tool;
- a grooving tool that is coupled to one side of the main body and for forming a Groove at an interior circumference of a workpiece;
- and a tool position control means that controls a position of the grooving tool to correspond to a cutting surface position of the workpiece, the method comprising:
- installing the grooving tool within a cylinder bore;
- measuring a distance between a cutting tip of the grooving tool and the cylinder bore;
- setting a moving position of the grooving tool in proportion to the measured distance and moving the grooving tool to the predetermined moving position;
- and
- processing a groove in the cylinder bore by the grooving tool by rotating the hybrid cutting apparatus.
