摘要:
A contour shape of a desired shape of a workpiece at section along a predetermined axis is divided into machining units. Each of the machining units includes a plurality of inflection points including a machining start point and a machining end point. Machining data at least necessary for performing machining is set for each of the machining units. Arrival times at the inflection points are calculated based on the machining data, and a position of at least one of the workpiece and the tool is calculated for each of the inflection points. For each of the machining units, a rotation angle position of the workpiece corresponding to the arrival time is set as an accumulated count value.

A CAM apparatus includes: an input receiving unit that receives designation of a part where core fixing machining is performed in a machining shape forming a core and divides the machining shape into a first machining shape element for which the core fixing machining is performed and a second machining shape element, which is connected to the first machining element and for which the core fixing machining is not performed, a machining-condition setting unit that allocates a first electric condition for the core fixing machining to the first machining shape element and allocates a second electric condition to the second machining shape element, and a machining-program generating unit that generates a machining program for machining the second machining shape element under the second electric condition and continuously machining the first machining shape element under the first electric condition after the machining of the second machining shape element.

A delete mark is displayed at the start end of a directional vector, and a finish mark at the other end thereof. The vector is deleted when the delete mark is touched, and input of the vector is completed when the finish mark is touched.

A cutting direction input method in automatic programming for deciding a path cutting direction, includes the following steps. A path trajectory comprising a number of path blocks (b.sub.1 .about.b.sub.15), is displayed on a display screen (105) by using path data, and a path starting point side (P.sub.2) or path end point side (P15) is indicated by a cursor (CSR). The cutting direction is entered by operating a cutting direction input switch when the path starting point side (P.sub.2) is being indicated by the cursor (CSR), in a case where cutting is to be performed from the path starting point (P.sub.1) toward the path end point (P.sub.16). The cutting direction is entered by operating the cutting direction input switch when the path end point side (P.sub.15) is being indicated by the cursor (CSR), in a case where cutting is to be performed from the path end point (P.sub.16) toward the path starting point (P.sub.1).

摘要:
A machining data forming system for a numerical control device in which machining data are inputted through interaction with a display unit. Since the present system is provided with a machining menu for a variety of machining position patterns, it is unnecessary to obtain the center or position coordinates of the machining position patterns. As a result, the number of interactive data inputting steps can be reduced to thereby improve the program inputting efficiency.

摘要:
A machining area specifying method for an automatic programming system specifies a partial path to be machined, wherein the path is part of a closed path. The machining area specifying method includes the step of displaying a closed path trajectory form by a number of path blocks (b.sub.1, b.sub.2 . . . b.sub.16) on a display screen (105) by using path data prepared beforehand. First and second points (P.sub.5, P.sub.12) on the closed path are entered by designating the points with a cursor (CSR). A point (P.sub.6) on a first path (P.sub.5 .fwdarw.P.sub.6 .fwdarw. . . . P.sub.12) and a point (P.sub.13) on a second path which are connected to the first and second points, are designated by the cursor. An area to be machined is specified by operating a machining area input switch when the first path is being designated by the cursor in a case where the first path is to be machined, while the machining area input switch is operated when the second path is being designated by the cursor in a case where the second path is to be machined.
