Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of machining a round hole in a work, the method comprising: a hole-shape acquisition step of acquiring a shape of a non-round hole of the work, wherein the shape of the non-round hole exhibits a diametrical difference relative to a target round shape at at least one circumferential angular position of the non-round hole; an inverted-shape acquisition step of inverting the diametrical difference of the shape of the non-round hole, acquired at the hole-shape acquisition step, to acquire an inverted non-round shape; and an inverted-shape machining step of machining the target round shape of the round hole in accordance with the inverted non-round shape acquired at the inverted-shape acquisition step, wherein the inverted-shape machining step is performed using a machining tool, and wherein the hole-shape acquisition step is performed based on positional information of the machining tool on a plane perpendicular to the axis of rotation of the machining tool. 2. A method of machining a round hole in a work, the method comprising: a non-round hole machining step applied to a work, to produce a non-round hole of the work by machining a round hole in the work, wherein the shape of the machined round hole changes to a non-round shape due to elastic deformation of the work subsequent to performing the non-round hole machining step; a hole-shape acquisition step of acquiring the non-round shape of the non-round hole produced by the non-round hole machining step, wherein the non-round shape exhibits a diametrical difference relative to a target round shape at at least one circumferential angular position of the non-round hole; an inverted-shape acquisition step of inverting the diametrical difference of the non-round shape, acquired at the hole-shape acquisition step, to acquire an inverted non-round shape; and an inverted-shape machining step of machining the target round shape of the round hole in accordance with the inverted non-round shape acquired at the inverted-shape acquisition step, wherein the inverted-shape machining step is performed using a machining tool, and wherein the hole-shape acquisition step is performed based on positional information of the machining tool on a plane perpendicular to the axis of rotation of the machining tool.
