Abstract
This invention is a tool for modifying the surface of a material, such as a metal for the primary purpose of improving adhesive bonding of the prepared material. The tool is a toothed burr-maker which, after application by pressure or impulse to the material to be prepared, leaves a very aggressive surface to which any adhesive will have a mechanical 'key' to bond onto the prepared surface with. The configuration of the tool is easily adapted to provide custom burrs in custom patterns and can be incorporated into a computer-guided operation to prepare selected areas of the workpiece. Self-clamping of the material is also supported through entwining of the opposing burrs. Fiber reinforcement of the bonded joint is also possible.

A method of modifying a workpiece presenting a generally planar surface, comprising planing without detachment a plurality of curved, elongated and at least partially retroverted cuttings from spaced, non-overlapping, elongated troughs of approximately constant depth distributed over said surface, the cuttings remaining continuous with the planar surface at one end of each trough, using at least one tool providing a planing action with a stroke which is small compared with the dimensions of the surface to be treated, whereby to provide the workpiece with a modified surface of increased surface area, part of which increased area is provided by surfaces of the cuttings which face towards and are spaced away from a remainder of the workpiece.
14. A workpiece presenting a generally planar surface with a plurality non-overlapping elongated channels cut in its surface with a non-detached curved, elongated, and at least partly retroverted cutting of said freely machineable material rooted at one end of each channel and springing from it initially in line with the channel and with said surface, the channels and cuttings being short compared with the dimensions of an area of the surface over which the channels are distributed.
means to hold said blade means in a stack with said operative edge contacting said material;
alignment means on said blade means, at least one said blade initially misaligned with the remainder;
means to advance said operative edges into said material to carve a plurality of furrows from which a like plurality of burrs are raised, and said means to advance also at least partially aligns said alignment means; and said means to advance also providing limit to said advance means to prevent severing said burrs.
8. A tool for raising a plurality of burrs from a surface portion only of a material comprising, a plurality of blade means having operative edge with cutting teeth thereon;
means to hold said blade means in a stack with said operative edge contacting said material;
alignment means on said blade means, at least one said blade initially misaligned with the remainder, means to advance said operative edges into said material to carve a plurality of furrows from which a like plurality of burrs are raised, and said means to advance also at least partially aligns said alignment means; and said means to advance also providing limit to said advance means to prevent severing said burrs and to prevent piercing said material.
9. Apparatus for modifying a generally planar surface of a workpiece, comprising at least one chisel member presenting a cutting edge at a planing angle to said surface, structure providing a gauging surface set back from said cutting edge and controlling depth of penetration of the cutting edge into the workpiece during planing movement of the cutting edge of each chisel member relative to the workpiece, structure providing a guide surface directing a cutting planed from the surface of the workpiece into a retroverting curve, and mechanism operable to repeatedly relatively displace each chisel member and the workpiece through a predetermined planing stroke whereby to plane a non-detached cutting of predetermined length from a trough in a first zone of the surface, and operable to withdraw the chisel member from planing engagement with the workpiece, and means for permitting movement of the workpiece relative to the chisel member so that a following planing stroke may be performed on a further zone of the surface spaced from the first zone.
10. Apparatus according to Claim 9, including at least one tool carrying multiple chisel members presenting cutting edges at a planing angle to multiple locations on said surface.
11. Apparatus according to Claim 10, including at least two tools presenting multiple chisel members directed in opposite directions.
12. Apparatus according to Claim 11, including means to simultaneously displace said tools or sets of tools into planing engagement with the workpiece in the direction in which their chisel members are directed.
13. A method of modifying a workpiece presenting a generally planar surface, comprising planing without detachment a plurality of curved, elongated and at least partially retroverted cuttings from spaced, non-overlapping, elongated troughs of approximately constant depth distributed over said surface, the cuttings remaining continuous with the planar surface at one end of each trough, using at least one tool providing a planing action with a stroke which is small compared with the dimensions of the surface to be treated, whereby to provide the workpiece with a modified surface of increased surface area, part of which increased area is provided by surfaces of the cuttings which face towards and are spaced away from a remainder of the workpiece.
14. A workpiece presenting a generally planar surface with a plurality non-overlapping elongated channels cut in its surface with a non-detached curved, elongated, and at least partly retroverted cutting of said freely machineable material rooted at one end of each channel and springing from it initially in line with the channel and with said surface, the channels and cuttings being short compared with the dimensions of an area of the surface over which the channels are distributed.
