Abstract:
A method of specifying a machining region for automatic programming, wherein part of a path to be machined is specified within a closed path, comprises the steps of displaying the locus of a closed path constituted by a plurality of path blocks (b1, b2...b16) on a display screen (105) using path data which is already prepared, indicating and inputting first and second points (P5, P12) on the closed path with a cursor (CSR), indicating with the cursor a point (P6) within a first path part (P5$(1,5)$P6$(1,5)$...$(1,5)$P12) between the first and second points and a point (P13) within a second path part (P12$(1,5)$P13$(1,5)$...$(1,5)$P'5), and specifying a region to be machined by actuating a machining region input switch when the first path part is indicated by the cursor when the first path part is to be machined, and when the second path part is indicated by the cursor when the second passage part is to be machined.
Abstract:
A method of inputting a cutting direction for automatic programming determining the cutting direction of a path comprises the steps of displaying the locus of a path constituted by a plurality of path blocks (b1 to b15) on a display screen (105) using path data, indicating with a cursor (CSR) an appropriate start point (P2) and an end point (P15) of the path, inputting a cutting direction by the operation of a cutting direction input switch when the path start point (P2) is indicated by the cursor (CSR) when cutting is to be effected from a start point (P1) to an end point (P16) of the passage, and inputting the cutting direction by the operation of the cutting direction input switch when the path end point (P15) is indicated by the cursor (CSR) when cutting is to be effected from the path end point (P16) to the start point (P1).
