Definitions

  • the present invention is directed to machine tools, such as tool grinding machines, and in particular to multi-axis, high precision, computer controlled machine tools for grinding of relieved tooth profiles of rotary cutting tools.
  • the present invention is directed to a machine tool with an angular oriented spindle that can be angularly positioned (swivel) thereby providing the flexibility to utilize both cup-shaped and pencil-shaped grinding wheels for grinding of hob and milling cutter relieved tooth geometry without exchanging grinding spindles assemblies or modifying the machine construction to accommodate two types of grinding methods or utilizing an additional machine axis for the spindle re-orientation.
  • Figures 1 (a), 1 (b) and 1 (c) illustrate the lead setting angular relationships of a cup-shaped grinding wheel to a hob tooth profile of universal module size.
  • Figures 2(a), 2(b) and 2(c) illustrate the lead setting angular relationships of a pencil-shaped grinding wheel to a hob tooth profile of universal module size.
  • Figure 3 shows the design planes relative to the radial cam relieving motion from the front to back profiles of the hob along the involute helicoids.
  • Figure 4 illustrates the change in pressure angle from front to back of the constant base pitch hob tooth profile.
  • Figure 5 illustrates the relationships and direction of cam relief for the machine major components, hob workpiece and grinding wheel spindle assembly orientated for using pencil-shaped grinding wheels.
  • Figure 6 illustrates the relationships and direction of cam relief for the machine major components, hob workpiece and grinding wheel spindle assembly orientated for using cup wheels
  • Figure 7 is an enlarged view of the inventive grinding spindle assembly in its operative position in a machine.
  • Figure 8 is an enlarged view of an automatic wheel exchange unit attached to the machine base for exchanging grinding wheel packs and coolant manifolds between the grinding spindle mounting interface and storage stations.
  • Figures 1 (a), 1 (b) and 1 (c) show the angular relationships of a grinding wheel in a coordinate system for a cup-shaped grinding wheel 1 in contact along a involute helicoid 2 of one of a sequential series of hob teeth 3 along a thread path 4 with single or multiple starts with a front profile 5 at the cutting face defined by the intersection of the thread involute helicoid 2 and a straight or helical flute 6 and with a relieved back profile 7 near the end of the sharpening life of the tooth position that is restricted in length by the interference point 8 of the grinding wheel 1 with the adjacent hob tooth 9 along the involute helicoid 2.
  • Relationships defined in Figures 1 (a), 1 (b) and 1 (c) are the fixed angle HA (angle 10) of the grinding spindle assembly, the grinding wheel pressure angle PA (angle 1 1 ), and the axial pressure angle APA (angle 12) of the hob tooth, the lead angles LASi and LAS 2 of the involute helicoids 13 as viewed from the front, and the swivel setting angle setting 14 of the grinding head assembly as viewed from the front, and the relieving direction 15 relative to the coordinate system.
  • Figures 2(a), 2(b) and 2(c) show the angular relationships of the grinding wheel in a coordinate system for a pencil-shaped or cone-shaped grinding wheel 16 in contact along a involute helicoid 17 of one of a sequential series of hob teeth 18 along a thread path 19 with single or multiple starts with a front profile 20 at the cutting face defined by the intersection of the thread involute helicoid 17 and a straight or helical flute 21 and with a relieved back profile 22 near the end of the sharpening life of the tooth position that is restricted in length by the interference point 23 of the grinding wheel 16 with the adjacent hob tooth 24 along the involute helicoid 17.
  • Relationships defined in the Figures 2(a), 2(b) and 2(c) are the fixed angle 25 of the grinding spindle assembly, angle B (angle 26) which is difference between pressure angle PA trued/dressed on the grinding wheel and the axial pressure angle APA (angle 27) of the hob tooth, the lead angles LASi and LAS2 of the involute helicoids 28 as viewed from the front, and the swivel setting angle setting 29 of the grinding head assembly as viewed from the front, and the relieving direction 30 relative to the coordinate system.
  • Figure 3 defines the design planes used for optimizing the grinding wheel geometry to reduce deviation from the theoretical tooth profiles with or without involute modifications and the inherent error of the hob tooth grinding wheel to tooth pressure angle conjugant contact points.
  • Design planes are defined at the front 31 , midpoint of cam relief 32 and back 33 sections. Also shown are the related nominal hob outside radius 34, nominal hob midpoint radius 35, and end of sharpening life nominal hob radius 36.
  • Figure 4 shows the characteristic error for a hob tooth of an involute profile produced by ordinary machine tool manufacturing methods. Theoretically, a new and different hob is produced every time the hob is sharpened from front to back. A sharpened hob will cut a gear only to the approximate form as the new hob. In addition, the more the hob is sharpened back, the worse the error becomes.
  • Figure 4 shows two axial sections of the hob tooth involute helicoid profile, without involute modifications for the illustration, representing the theoretically correct front position of a new hob 37 and the sharpened back position 38 near the end of the sharpening life along the tooth involute helicoid.
  • the inherent error 39 occurs when a grinding wheel or form tool, which by nature has a fixed geometric profile, attempts to contact this helicoid surface at both sections 37 and 38 when driven in a fixed path by the machines relieving motions.
  • error A and error B The recognition of the inherent error problem discussed above and attempts to solve are known from "Buckingham, Earl, Spur Gears, McGraw-Hill Book Co. Inc., NY, 1928", wherein it is discussed relieving hob tooth surfaces utilizing special characteristic of the involute helicoids. With the disclosed method, contact between the relieved surface and the grinding wheel will be the straight line generatrix of the involute helicoids and the relieved surface itself will be an involute helicoid.
  • the CNC Controller (such as a Fanuc 160 ⁇ computer control) of the inventive grinding machine is operable to provide the radial or offset radial cam relieving motion either from a single axis moving in a horizontal plane when the grinding head assembly is positioned about a horizontal plane for using cup wheels for grinding, or at a compound angle about the vertical plane using multiple axes to provide the cam relieving motion when the grinding head assembly is positioned about a vertical plane for using pencil wheels for grinding.
  • the grinding head assembly is capable of imparting an oscillating motion to the grinding wheel superimposed on the radial or offset radial cam relieving motion which acts to change the swivel orientation of the grinding wheel relative to the pressure angle of the hob tooth profile thereby reducing the tooth pressure angle at the back of the hob tooth relative to the front and midpoint of the relieved tooth profile.

  • the preferred 25 degree orientated grinding spindle can also facilitate pencil shaped grinding wheels 52 ( Figure 5) with the grinding wheel head 40 positioned approximately plus or minus 40 degrees or thereabout from a vertical plane resulting in a relief grinding motion using both quick vertical and horizontal motions combined with rotary and longitudinal motions.
  • the grinding wheel head assembly can be oscillated approximately plus or minus 31 ⁇ 2 degrees from the setup angular position during the relief motions to produce coarse module normal base pitch hobs which will have corrected tooth profile pressure angle at the back as well as at the front relieved hob tooth flank.
