Slow grinding technique

Claim 2

In the process of removal of material from a workpiece having a low machinability factor by a single pass grinding operation with a minimum amount of wheel wear, the steps of rotating a grinding wheel to produce a surface speed of from 1600 to 2000 surface feet per minute, feeding the grinding wheel relative to the work at a speed of from 1/4 to 2 inches per minute, positioning the wheel relative to the workpiece for removal of a depth of material greater than 0.100 inch in a single pass of the workpiece relative to the wheel, and supplying coolant to the contact area between the wheel and workpiece.

Claim 3

The process of claim 1 in which the removal of material produces a slot in the workpiece with opposed finished surfaces.

Claim 4

The process of removing material by grinding from a workpiece of a material having a low machinability factor by grinding with a minimum amount of grinding wheel wear, including the steps of rotating the grinding wheel to provide a surface speed of about 1600 to 2000 surface feet per minute, feeding the workpiece against the grinding wheel at a feed rate of between about 1/4 and 1 inch per minute, and positioning the wheel relative to the workpiece for removal of a depth of material from 0.100 inch to 0.600 inch in a single pass of the workpiece relative to the wheel.

Claim 5

The process of removing material by grinding from a workpiece of a material having a low machinability factor by grinding with a minimum amount of grinding wheel wear, including the steps of rotating the grinding wheel to provide a surface speed of about 1600 to 2000 surface feet per minute, feeding the workpiece against the grinding wheel at a feed rate of between about 1/4 and 1 inch per minute, and positioning the wheel relative to the workpiece for removal of a depth of material from 0.100 inch to 0.600 inch in a single pass of the workpiece relative to the wheel.

Claim 6

The process of claim 3 including the step of supplying coolant to the contacting surfaces of the wheel and workpiece to prevent undesired heating of either wheel or workpiece surfaces.

Claim 7

The process of claim 3 in which the material is a material subject to surface damage by conventional cracking, and in which the depth of cut is between 0.100 and 0.350 inches in a single pass of the wheel.

Claim 8

The process of claim 3 in which the material is AMS5706 or the like, and wherein the depth of cut is more than 1/2 inch, the wheel speed is about 1800 surface feet per minute and the feed is about 158 inch per minute.

Claim 9

The process of claim 3 in which the material is titanium, the depth of cut is about 0.100 inch and the wheel speed is about 1800 surface feet per minute.

Claim 10

The process of removing material by grinding from a workpiece of a material having a low machinability factor to form a notch in the workpiece having two surfaces at right angles and a corner radius therebetween without significant wear on the wheel during the operation, including rotating the grinding wheel to provide a surface speed of from 1600 to 2000 surface feet per minute, feeding the workpiece against the grinding wheel at a feed rate of between 1/4 and 1 inch per minute, positioning the wheel relative to the workpiece to remove a depth of material from 0.100 to 0.600 inches in a single pass of the wheel relative to the work, and maintaining the desired notch contour without redressing the wheel during the operation.

Claim 11

The process of removing material by grinding from a workpiece of a material having a low machinability factor to form a notch in the workpiece having two surfaces at right angles and a corner radius therebetween without significant wear on the wheel during the operation, including rotating the grinding wheel to provide a surface speed of from 1600 to 2000 surface feet per minute, feeding the workpiece against the grinding wheel at a feed rate of between 1/4 and 1 inch per minute, positioning the wheel relative to the workpiece to remove a depth of material from 0.100 to 0.600 inches in a single pass of the wheel relative to the work, and maintaining the desired notch contour without redressing the wheel during the operation.
