Definitions

  • the present invention relates to the machining of slots by use of a rotational cutting tool. More particularly, the invention provides an end mill, which can be used for different machining purposes by changing the distance between a thin workpiece and the end mill shank. This change is accomplished either by moving the workpiece or the cutter.
  • a common requirement is to machine a slot, straight or contoured, in a thin workpiece. “Thin” means that the machined item is usually no thicker than the tool diameter.
  • the required slot reaches an outer edge of the workpiece, or the operation to be carried out comprises machining the outer edge, then the first operation is rough machining, leaving a little material for finishing, and the following operation is finish machining to the required size.
  • End-mills configured for rough machining are generally unsuitable for finish machining. During rough machining much material is removed, and the removal of chips from the cutting area requires adequate space between cutting teeth. Such space can only be provided when the number of teeth is low, typically 2-4 teeth depending on cutter diameter, and the core diameter of the tool is small, although still large enough to prevent tool breakage. The smaller core diameter may lead to minor loss of accuracy due to tool bending under pressure, but this is of little moment for roughing operations.
  • the first operation is drilling a hole to allow entry for the end-mill.
  • Many end-mills are provided with cutting teeth at the end face of the tool, and it is possible to use such an end-mill for drilling.
  • Such operation requires high pressure, machining time is extended and the hole produced could be oversize or even off its intended position.
  • a drill can be used to produce the hole, but of course this involves more changeover time. After the hole is drilled, the slot is rough machined and then finish machined as described above.
  • the present invention achieves the above objects by providing a multi-purpose end-mill particularly useful for closed contour machining and usable for at least rough machining and finish machining, comprising a cylindrical shank portion to be gripped in a machine tool, said shank portion being connected to a first cutting portion comprising a core supporting a plurality of spaced-apart cutting teeth for a first type of machining, said first cutting portion being connected to a second cutting portion provided with a plurality of spaced-apart cutting teeth for a second type of machining.
  • a multi-purpose end-mill wherein said first type of machining is finishing, and said second type of machining is roughing.
  • a multi-purpose end-mill further provided with a drill-like pointed cutting tip.
  • the cutter of the present invention can used for machining most metals, including stainless steel and high temperature alloys such as Inconel 718 and Rene 41.
  • tooth clearance angle is about 4 degrees for hard materials, 6 degrees for softer metals and about 11 degrees for easy-to-machine materials.
  • Rake angles are about 10 degrees for machining hard materials and up to 25 degrees for magnesium, aluminium and plastics.
  • the present tool typically made of high speed steel, can be made partly of tungsten carbide where production quantities justify the cost. Also, coolant passages can be provided in the tool, as is sometimes found on prior art cutters.
  • FIG. 1 is a perspective view of a preferred embodiment of the end mill according to the invention.
  • FIG. 2 is an elevational view of an embodiment wherein the tooth helix angle is different for each part of the cutter
  • FIG. 3 is a partly sectioned elevational view of an embodiment having a parabolically shaped core
  • FIG. 4 is similar to FIG. 2 , with the addition of a drill point
  • FIG. 5 is a perspective view of a workpiece produced by an end mill of the type seen in FIG. 2 ;
  • FIG. 6 is a view of a perspective view of a workpiece produced by an end mill of the type seen in FIG. 4
  • FIG. 1 a multi-purpose end-mill 10 particularly useful for open contour machining, for example producing a workpiece of the type seen in FIG. 5 .
  • the end mill 10 is suitable for both rough machining and finish machining.
  • a cylindrical shank portion 12 is arranged to be gripped in a machine tool (not shown), such as a router or a milling machine, and in some types of work even a lathe or drilling machine.
  • a machine tool such as a router or a milling machine
  • the shank portion 12 is connected to a first cutting portion 14 comprising a core 16 supporting a plurality of spaced-apart cutting teeth 18 for a first type of machining.
  • the first cutting portion 14 is connected to a second cutting portion 20 provided with a plurality of spaced-apart cutting teeth 22 for a second type of machining.
  • the first type of machining is finishing, and the second type of machining is roughing. This is the arrangement in the shown embodiment. However, if special considerations so warrant, this order can be reversed.
  • the first cutting portion 14 which is the finishing portion has a larger number of teeth than the second cutting portion 20 which is the roughing portion.
  • the finishing portion 14 has double the number of teeth, for example 4 in the present embodiment, than the roughing portion 20 which has 2 teeth 22 .
  • movement in the Z axis to change between roughing and finishing can be accomplished by raising/lowering the work table, or it may be more convenient to raise/lower the cutter spindle.
  • the machine table is moved in the Y axis to change between roughing and finishing.
  • FIG. 2 illustrates a multi-purpose end-mill 24 similar to 10 seen in the previous figure.
  • the finishing portion 26 has a smaller helix angle than the roughing portion 28 .
  • Tooth helix angle of an end-mill is partly dependent on the number of teeth; the following values are however typical.
  • the roughing portion 28 has a tooth helix angle of about 25° to reduce vibration.
  • the finishing portion 26 has a more moderate helix angle of about 10° to produce a smooth finish.
  • Seen in FIG. 3 is a multi-purpose end-mill 30 wherein the core 31 diameter, seen shaded, of the end-mill varies parabolically along the axial length, the larger diameter being located near the shank 32 and the smaller diameter being located near the tool tip 34 .
  • This form is ideal for resisting the bending moment in an end-loaded cantilever beam, a model approximately representing the bending stress on the end mill during use.
  • FIG. 4 there is depicted a multi-purpose end-mill 36 further provided with a drill-like pointed cutting tip 38 .
  • the tip 38 enables quick and accurate drilling of a hole at any desired point (usually an end point) of a profile path to be milled.
  • the hole is needed to allow cutter access for rough milling of a slot 40 of the type seen in FIG. 6 .
  • the number (2) of cutting teeth 42 at the pointed cutting tip 38 corresponds to the number (2) of teeth 44 in the second cutting portion 46 .
  • the advantage therein is that the tip cutting edges 42 are well supported and that there are unobstructed paths for chip clearance between the teeth 44 .
  • FIG. 5 shows a machined workpiece 48 having one edge machined as a concave curve 50 and having a slot 52 meeting the curve 50 . Both the slot 52 and the curve 50 have been rough and finish machined by the multi-purpose end-mill 24 in FIG. 2 .
  • FIG. 6 illustrates a machined workpiece 54 having one edge machined as a concave curve 56 .
  • the closed path slot 40 required three machining operations—drilling, rough machining and finishing. All machining was completed by use of the multi-purpose end-mill 36 provided with a drill-like pointed cutting tip 38 seen in FIG. 4 , without changing the tool.
