Abstract
Abstract An orthotic, for providing proper support for a patient's foot within a shoe has provided on its top and bottom surfaces closely spaced substantially parallel grooves. The grooves on the top surface control slippage of the foot across the orthotic while the grooves on the bottom surface of the orthotic control slippage of the orthotic relative to the shoe's insole. The orthotic is shaped from a single monolithic workpiece by guiding a computer-controlled milling tool along substantially closely spaced parallel passes in a preselected pattern across the workpiece to thereby produce the orthotic's surface contours and surface texture in a single operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
A method for producing from a workpiece a non-compressive, weight bearing orthotic device for providing proper support for a patient's foot within a shoe, such orthotic device having a top surface for contacting the foot and a bottom surface for contacting a shoe's insole, comprising the steps of: generating data geometrically descriptive of such orthotic device's desired top surface contour and bottom surface contour; storing said data in a form suitable to provide a height position to a machine tool for any longitudinal and lateral position on such workpiece's top and bottom surfaces; selecting a workpiece of machinable material capable of functionally or biomechanically supporting a patient's foot; and guiding a machine tool, subject to automatic height adjustments commensurate with said stored data, along successive passes across such workpiece so that an orthotic device having the desired top and bottom surface contours results, and spacing such passes so that closely spaced, substantially parallel grooves are formed in the top and bottom contoured surfaces.
Claim 2
Independent Claim
163 words
A method for producing from a workpiece a non-compressive, weight bearing orthotic device for providing proper support for a patient's foot within a shoe, such orthotic device having a top surface for contacting the foot and a bottom surface for contacting a shoe's insole, comprising the steps of: generating data geometrically descriptive of such orthotic device's desired top surface contour and bottom surface contour; storing said data in a form suitable to provide a height position to a machine tool for any longitudinal and lateral position on such workpiece's top and bottom surfaces; selecting a workpiece of machinable material capable of functionally or biomechanically supporting a patient's foot; and guiding a machine tool, subject to automatic height adjustments commensurate with said stored data, along successive passes across such workpiece so that an orthotic device having the desired top and bottom surface contours results, and spacing such passes so that closely spaced, substantially parallel grooves are formed in the top and bottom contoured surfaces.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein: said machine tool is guided along successive passes along such orthotic's longitudinal axis.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein: said machine tool is guided to follow such orthotic's surface contours in a topographical fashion.
Claim 5
Dependent Claim
18 words
The method of claim 1 wherein: said machine tool comprises a ball-shaped milling tool having a preselected diameter.
Claim 6
Dependent Claim
34 words
The method of claim 4 wherein: said diameter is selected and successive passes are spaced so that grooves approximately 2 mm wide, 0.10 mm deep, and spaced at approximately 12 grooves per inch result.
