Abstract
Abstract The invention relates to a part profile input method for inputting the profile elements of a part using arrow keys. When inputting a part profile, an angle (A i ) defined by two mutually adjacent profile elements (EL i , EL i+1 ) is computed, and whether the corner is in outside corner or an inside corner is determined by comparing the angle of intersection and a set angle. In case of an outside corner, a preset chamfer dimension (DIM) is displayed. If the dimension is acceptable, an input key is pressed to input the chamfer profile (CF) at the corner portion. In case of an inner corner, a prompt display is presented inquiring whether a rounded profile is to be inserted. If insertion is required, a dimension is inputted and the input key is pressed to input the rounded profile.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
127 words
A part profile input method in an NC data creating apparatus in which a part profile is specified by inputting profile elements of a part and inputting dimensions specifying the profile elements, and NC data are created for machining a blank in accordance with the specified part profile, said method comprising the steps of: inputting a current profile element; determining if an angle can be defined by said profile element and a previously inputted profile element; defining said angle if it can be determined; displaying a prompt inquiring if a displayed preset dimension chamfer is to be inserted at a corner portion of the current profile element and the previously inputted profile element; and specifying the corner portion if said angle is less than a set angle.
Claim 2
Dependent Claim
127 words
A part profile input method in an NC data creating apparatus in which a part profile is specified by inputting profile elements of a part and inputting dimensions specifying the profile elements, and NC data are created for machining a blank in accordance with the specified part profile, said method comprising the steps of: inputting a current profile element; determining if an angle can be defined by said profile element and a previously inputted profile element; defining said angle if it can be determined; displaying a prompt inquiring if a displayed preset dimension chamfer is to be inserted at a corner portion of the current profile element and the previously inputted profile element; and specifying the corner portion if said angle is less than a set angle.
Claim 3
Dependent Claim
39 words
A part profile input method according to claim 1, further comprising the steps of: inputting a chamfer having a dimension different from said displayed preset dimensioned chamfer; and revising said displayed preset dimension in accordance with said inputted chamfer.
Claim 4
Dependent Claim
58 words
A part profile input method according to claim 1, further comprising the steps of: displaying a prompt inquiring if a rounded profile is to be inserted at the corner portion of the current profile element and the previously inputted profile element if said angle is greater than a set value; and specifying the shape of the corner portion.
Claim 5
Dependent Claim
55 words
A part profile input method according to claim 1, further comprising the steps of: displaying a prompt inquiring if a rounded profile is to be inserted at the corner portion of the current profile element and the previously inputted profile element if said angle cannot be determined; and specifying the shape of the corner portion.
