Abstract

PURPOSE:To shorten the man-hour for preparing outline working data, when a plurality of outline working data are worked, by investigating the access condition of respective outline working data, and converting the outline working data in such an order that an accurate outline working can be carried out for outline working data having been input. CONSTITUTION:Outline working data are input into a data input part 1, and once they are made to read in a data storing part 2, and then these data are successively delivered to a working order conversion processing part 3. In the processing part 3, when working graphic data are constituted, for example, in the order of a closed loop figure P1 to P6P1, and a closed loop figure P7 to P12P7, the outline working data are resolved into closed loop graphic units in a resolving process. And whether there is such access as requiring the consideration in the order of outline working within the closed loop figures is investigated. In this case, if there is such access as requiring the consideration in the order of outline working in the figure P4P5 and in the figure P12P7, the access part P12P7 out of the closed loop figure P7 to P7 is rearranged in the conversion process so that it can be first worked, and is converted into P12P7 to P10P12 to deliver it to a working machine control data conversion processing part 4.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a machining order conversion device for a contour machining machine. This invention relates to a mechanism that converts the machining order within a closed-loop figure into an optimal order for external shape machining.

[Conventional technology]

Conventionally, a data conversion device for this type of contour processing machine has been configured as follows. FIG. 3 is a block diagram showing the configuration of a data conversion device for a conventional contour processing machine. In the same figure, the external shape machining data includes machining figure data consisting of closed-loop figures and control of the used machining tools'! il - front cover processing control data, and this external processing data is sent to the data input unit 1 before data conversion of the external processing data.
The data is read into the data storage unit 2 via the .

Next, the external shape processing data read into the data storage section 2 is sequentially delivered to the processing machine control data conversion processing section 4. This processing machine control data conversion processing section 4 converts the external processing data into processing machine control data necessary for controlling the external processing machine and returns it to the data storage section 2. When the data conversion process is completed for all the contour machining data read into the data storage section 2, the data is outputted as processing machine control data of the contour machining machine via the data output section 5 and handed over to a subsequent process.

[Problem to be solved by the invention]

However, the conventional data conversion device for the contour processing machine described above has the following problems.

As shown in the schematic plan view of the external processing plate in Fig. 4, when processing the processing plate 1 (l processing plate holding position 1tlL 12) and processing a plurality of external processing data, the processing order is the input external processing. Follow data order.

For example, if the input order of the external shape processing data is a closed-loop shape P
! If the order is Px Pg P4 Pl Ps P+ and the closed-loop figure P7 PgPI PIOpHPlz Pt, the figure P12P7 is processed last. At this time, if the interval between the figure Ps Pt and the figure Pt* Pt is narrow, P1! Before the external shape of P7 is processed, the strength becomes insufficient, and an accident occurs in which the tool comes off or shifts from the intended external processing position, making it impossible to perform external processing at an accurate position.

In order to avoid these drawbacks, the outline machining data must be created with the order of the outline machining in mind, or the interval between each closed loop figure in the outline machining data must be widened. It took a great deal of time to create the data, and errors in data creation were inevitable.

An object of the present invention is to improve the shortcomings of the conventional profile processing machine data conversion device described above, and when processing a plurality of profile processing data, tabulate the proximity state of each profile processing data, and input the input profile processing data. It is an object of the present invention to provide a machining order converting device for a contour machining machine which is capable of converting contour machining data into an order in which accurate contour machining can be carried out.
