Method to hone curved and shaped profiles which belong to furniture elements, which are advantageously of furniture of an antique style, such as surfaces of tables, mouldings of furniture or pictures, panels, doors of kitchen cupboards, seat elements, etc., the profile to be honed of which includes at least one shaping with projections (35) and valleys (34) positioned close together, the method including a step of continuous identification and reading of each position of the profile of the specific piece (11) to be honed by means of a profile-reader assembly (17), a step for storage of the data relating to that profile/position, and a step of transfer of such data to an operating unit (18) equipped with a relative operating element (32) that performs the honing with a resulting governing of the position of that operating unit (18) in relation to the piece (11) to be honed, this step of transfer of the data taking place with a delay after the step of identification and reading, this delay being a function of the circumferential position of the operating unit (18) in relation to the profile-reader assembly (17) and being a function of the relative speed of feed of the piece (11) to be honed in relation to operating element (32), the method including also steps of automatic compensation of the wear of the operating element (32) and steps of compensation of the intensity of the honing action of the operating unit (18), these compensation steps depending on the geometric and structural characteristics of the profile of the piece (11) to be honed, on the characteristics of the operating element (32) and on the type of processing performed. Honing machine which performs the above method.
A method of honing profiles of furniture components, wherein a profile is at least partly curved or shaped, comprising (1) continuously identifying and reading each geometric configuration of a profile of a furniture component to be honed by means of a profile reader assembly including a feeler unit which identifies a radius of curvature of the geometric configuration of each curve or shape present in the profile prior to said curve or shape being honed;
Apparatus for honing profiles of furniture components wherein a profile is at least partly curved or shaped comprising displacement means for displacing a furniture component to be honed wherein the displacement means moves a profile of the furniture component into cooperation with at least one processing assembly of the apparatus, wherein each processing assembly comprises at least one profile reader assembly which includes a feeler unit which reads the profile of the furniture component by identifying a radius of curvature of a geometric configuration of a curve or shape present in the profile prior to said curve or shape being honed and at least one operating unit including an operating element positionable in at least one inactive position distanced from said furniture component and in at least one working position in contact with the profile of the furniture component when the furniture component is moving, and wherein said at least one profile reader assembly is positioned in a predetermined spatial relationship with the operating unit;
