Publication number: 20030143049Abstract: A hand tool apparatus uses a cutting tool with a first width and a tool axis to machine a hole in an object. The hole has a second width at least as large as the first width of the cutting tool. The tool axis passes through a predetermined point on a surface of the object. The apparatus includes an actuating assembly including a housing. The housing contains an axial feed mechanism configured for moving the cutting tool in an axial direction, a spindle motor configured for rotating the cutting tool about the tool axis, and a radial offset mechanism. The radial offset mechanism is configured for moving the axial feed mechanism in a radial direction such that the tool axis is offset from a principal axis. A motor is configured for rotating said axial feed mechanism and the cutting tool about the principal axis.Type: ApplicationFiled: January 16, 2003Publication date: July 31, 2003Applicant: Novator ABInventor: Dag G. Linderholm

Publication number: 20030113181Abstract: A hand tool apparatus uses a cutting tool with a first width and a tool axis to machine a hole in an object. The hole has a second width at least as large as the first width of the cutting tool. The apparatus includes a housing, a spindle unit in the housing for rotating the cutting tool and an orbital drive for rotating the spindle unit. An axial feed mechanism moves the orbital drive and the spindle unit jointly either toward or away from the object being machined.Type: ApplicationFiled: January 15, 2003Publication date: June 19, 2003Applicant: Novator ABInventors: Dag G. Linderholm, Erik Bjork

Publication number: 20020131842Abstract: A fastener assembly is inserted into a throughhole of a composite laminate to thereby fasten the composite laminate together. The throughhole has a length extending from a first outer surface of the composite laminate to a second outer surface of the composite laminate. The throughhole has a first width at the first outer surface, a second width at the second outer surface, and a third width at a point along the length of the throughhole between the first outer surface and the second outer surface. The third width is less than each of the first width and the second width. The fastener assembly includes a substantially annular fastener device having an axial opening and a peripheral surface substantially conforming to the inner surface of the throughhole.Type: ApplicationFiled: April 17, 2002Publication date: September 19, 2002Applicant: Novator ABInventor: Ingvar Eriksson

Patent number: 6129489Abstract: Equipment for making a hole or cavity formation in a curved or planar wall element, and for cutting out a disc-shaped piece of material fitting the hole or cavity formation, includes a frame with devices for fixing it on the wall element, and a carriage displaceably mounted in a first linear direction. A slide is mounted to be displaceable in a direction perpendicular to the first linear direction and carries a tool unit. The carriage has wheel sets which are biased against the wall element. The wheel sets are pivotable and displaceably mounted on a respective guide slide, which is mounted to be displaceable in the first linear direction.Type: GrantFiled: August 13, 1998Date of Patent: October 10, 2000Assignee: Novator ABInventor: Dag Linderholm

Patent number: 6007281Abstract: A method of producing a hole in a fiber reinforced composite material workpiece includes the step of providing a cutting tool having a shaft, a cutting head, and an axis of rotation. The cutting head has a diameter which is substantially smaller than the diameter of the hole that is produced. The shaft has a diameter which is substantially smaller than the diameter of the cutting head. The cutting head has a height which is substantially smaller than the depth of the hole that is produced. The cutting tool is oriented such that the axis of rotation of the cutting tool is substantially orthogonal to the surface of the workpiece. The workpiece is simultaneously machined in both an axial and a radial direction relative to the longitudinal axis of the hole, by simultaneously rotating the cutting tool around the axis of rotation, moving the cutting tool in an axial direction, and moving the cutting tool eccentrically around the longitudinal axis of the hole.Type: GrantFiled: April 9, 1998Date of Patent: December 28, 1999Assignee: Novator ABInventors: Ingvar Eriksson, Dag G. Linderholm, Leif V. T. Zackrisson

Patent number: 5971678Abstract: An apparatus for machining a hole in a work piece includes a spindle motor that is rotatable about a principal axis. The spindle motor includes a tool holder having a tool axis substantially parallel to the principal axis. The tool holder is rotatable about the tool axis. An axial actuator is configured for moving the spindle motor in an axial feed direction substantially parallel to each of the principal axis and the tool axis. A radial actuator is configured for adjusting a radial distance between the principal axis and the tool axis.Type: GrantFiled: June 5, 1998Date of Patent: October 26, 1999Assignee: Novator ABInventor: Dag G. Linderholm

Patent number: 5641252Abstract: The invention relates to a method for producing a hole in a workpiece consisting of a fibre-reinforced composite material. The central axis of the hole passes through a predetermined point on the surface of the workpiece and is oriented in a certain determined direction in relation to the longitudinal directions of the fibres in the immediate vicinity of the point. The material is machined simultaneously in both an axial and a radial sense by causing the tool to describe an axial motion and to rotate not only about its own axis (5), but also eccentrically about the central axis.Type: GrantFiled: June 23, 1995Date of Patent: June 24, 1997Assignee: Novator ABInventors: Ingvar Eriksson, Jan Backlund, Leif Zackrisson
