An Electro Chemical Grinding (ECG) quill includes a tool manufactured of a porous tool material having a multitude of pores. An ECG electrolyte is communicated through a hollow tool shank for communication through the porous tool material to manufacture a slot.

대표청구항 ▼

1. An Electro Chemical Grinding (ECG) quill comprising: a shaft defined along an axis of rotation; anda tool mounted to said shaft, said tool manufactured of a porous tool material having a multitude of pores, disposed throughout the porous tool material, which extend from said shaft to an outer surface, said tool symmetrical defined about said axis of rotation. 2. The ECG quill as recited in claim 1, wherein said porous tool material comprises a 316N1 stainless 100 micron porous metal. 3. The ECG quill as recited in claim 1, wherein said outer surface comprises a shaped outer surface. 4. The ECG quill as recited in claim 3, wherein said shaped outer surface comprises a three-dimensional fir-tree shape. 5. The ECG quill as recited in claim 1, further comprising abrasive grains electroplated to said porous tool material to define a cutting surface. 6. The ECG quill as recited in claim 1, wherein a bottom surface of said tool opposite said shaft is relieved. 7. The ECG quill as recited in claim 1, wherein said shaft comprises a hollow shank which defines a multiple of apertures transverse to said axis, said multitude of pores in fluid communication with said hollow shank. 8. The ECG quill as recited in claim 7, wherein each of said multitude of pores operates hydraulically as an individual, high UD (Length to Diameter) flow rate system to ensuring a nearly constant flow rate therethrough. 9. An Electro Chemical Grinding (ECG) quill comprising: a shaft defined along an axis of rotation, said shaft comprises a hollow shank which defines a multiple of apertures transverse to said axis; anda tool mounted to said shaft, said tool manufactured of a porous tool material having a multitude of pores, wherein the multitude of pores are randomly arranged, in fluid communication with said hollow shank through said multiple of apertures, said tool symmetrical defined about said axis of rotation. 10. The ECG quill as recited in claim 9, wherein said porous tool material comprises a 316N1 stainless 100 micron porous metal. 11. The ECG quill as recited in claim 9, wherein each of said multitude of pores operates hydraulically as an individual, high L/D (Length to Diameter) flow rate system to ensuring a nearly constant flow rate therethrough. 12. The ECG quill as recited in claim 9, wherein said outer surface comprises a convoluted outer surface. 13. The ECG quill as recited in claim 12, wherein said convoluted outer surface comprises a three-dimensional fir-tree shape. 14. A method of machining a slot comprising: communicating an Electro Chemical Grinding (ECG) electrolyte through a hollow tool shank defined along an axis of rotation for communication through a tool symmetrical defined about the axis of rotation, the tool manufactured of a porous tool material as said tool is rotated about said axis of rotation. 15. A method as recited in claim 14, further comprising: attaching a direct Current (DC) ECG supply voltage to the hollow tool shank and to a workpiece. 16. A method as recited in claim 14, further comprising: communicating the ECG electrolyte to exit uniformly from an outer surface of the tool. 17. The ECG quill as recited in claim 1, wherein said shaft includes a multiple of apertures transverse to said axis of rotation. 18. The ECG quill as recited in claim 1, wherein said shaft is fixed within a central blind hole of said tool. 19. The ECG quill as recited in claim 1, wherein the multitude of pores are randomly arranged. 20. The method as recited in claim 14, wherein the porous tool material includes a multitude of randomly arranged pores.
