Abstract
Abstract An automatic programming method for creating an NC program by inserting miscellaneous data, such as M-function instruction data, feed rate instruction data, G-function instruction data and S-function instruction data, into previously created path data is disclosed. The method includes steps of displaying a path trajectory comprising a number of path blocks (b 1 , b 2 . . . b 16 ) on a display screen (105) by using the path data, positioning a cursor (CSR) at a prescribed position on the path trajectory, entering the miscellaneous data, and inserting the miscellaneous data into a block which is the same as that of the path data which correspond to a path block designated by the cursor, or at least at the front or rear of the block.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
An automatic programming method for creating an NC program by inserting miscellaneous data into previously created path data including path blocks, comprising the steps of: displaying a path trajectory comprising a number of the path blocks on a display screen by using said path data; positioning a cursor at a prescribed position on the path trajectory; accepting entry of the miscellaneous data; and inserting the miscellaneous data in front of or into the path data which corresponds to the path block designated by the cursor.
Claim 2
Dependent Claim
85 words
An automatic programming method for creating an NC program by inserting miscellaneous data into previously created path data including path blocks, comprising the steps of: displaying a path trajectory comprising a number of the path blocks on a display screen by using said path data; positioning a cursor at a prescribed position on the path trajectory; accepting entry of the miscellaneous data; and inserting the miscellaneous data in front of or into the path data which corresponds to the path block designated by the cursor.
Claim 3
Dependent Claim
44 words
An automatic programming method according to claim 1, further comprising a step of obtaining starting point coordinates of each path block constituting the path trajectory, the cursor being displayed at a starting point of a designated path block by using said starting point coordinates.
Claim 4
Dependent Claim
82 words
An automatic programming method according to claim 1, wherein said method is performed by a numerical controller including a first switch for advancing the cursor and a second switch for backing up the cursor, the cursor being advanced one block at a time in a tool travelling direction each time the first switch is pressed, and the cursor being moved backward one block at a time in a direction opposite to the tool travelling direction each time the second switch is pressed.
Claim 5
Dependent Claim
55 words
An automatic programming method according to claim 1, wherein the step of inserting includes identifying a letter of the alphabet contained in the miscellaneous data and determining whether the miscellaneous data are to be inserted into path data designated by the cursor or in front of said path data in dependence upon the letter identified.
Claim 6
Dependent Claim
29 words
An automatic programming method according to claim 1, wherein the miscellaneous data includes M-function instruction data, T-function instruction data, S-function instruction data, feedrate instruction data and G-function instruction data.
Claim 7
Dependent Claim
57 words
An automatic programming method according to claim 1, wherein the step of inserting the miscellaneous data includes identifying whether the cursor is positioned at a starting point, an intermediate point, or an end point of the path block, and determining where the miscellaneous data is inserted in dependence on the point at which the cursor is positioned.
