Abstract
Provided are a machining method and a machining device that can reduce the displacement from a target round shape due to elastic deformation after machining, and can shorten the time required to machine a target round shape in the work. A machining method machines a round hole in a work, and includes: a hole-shape acquisition step of acquiring a shape of a hole of the work; an inverted-shape acquisition step of inverting the shape of the hole acquired at the hole-shape acquisition step relative to a target round shape to acquire an inverted shape; and an inverted-shape machining step of machining the hole in accordance with the inverted shape acquired at the inverted-shape acquisition step.
Claims5
A method for machining a round hole in a work, the method comprising:
- a hole-shape acquisition step of acquiring a shape of a hole of the work;
- an inverted-shape acquisition step of inverting the shape of the hole acquired at the hole-shape acquisition step relative to a target round shape to acquire an inverted shape;
- and
- an inverted-shape machining step of machining the hole in accordance with the inverted shape acquired at the inverted-shape acquisition step.
A machining device that machines a hole in a work, comprising:
- a machining tool;
- a rotary device that rotates the machining tool;
- a rotation angle sensor that acquires an angle of rotation of the machining tool;
- a driving unit that moves the machining tool in a direction perpendicular to an axis of rotation of the machining tool;
- a position sensor that acquires positional information on the machining tool on a plane perpendicular to the axis of rotation of the machining tool;
- and
- a controller that includes a driving/control unit that controls the rotary device and controls the driving unit in accordance with the angle of rotation acquired by the rotation angle sensor and the positional information acquired by the position sensor, wherein
- the controller includes a hole-shape acquisition unit configured to acquire a shape of a hole of the work;
- and
- an inverted-shape acquisition unit configured to invert the shape of the hole acquired at the hole-shape acquisition unit relative to a target round shape to acquire an inverted shape, and
- the driving/control unit controls the driving unit in accordance with the inverted shape acquired by the inverted-shape acquisition unit.
