[Detailed description of the invention] [Industrial applications]

The present invention relates to a shape data input device for processing a workpiece with an NC grinder or the like.

[Prior art]

2. Description of the Related Art Conventionally, for example, an interactive shape data input device is used to input shape data for processing a workpiece with an NC grinding machine or the like. In a setup operation using this interactive shape data input device, first, as shown in FIG. 7, a plurality of basic shape patterns (hereinafter referred to as "basic shape patterns") displayed on a CRT display device are operated by a keyboard operation as shown in FIG. )), The n-th basic shape pattern, which is the preceding stage of the processing of the workpiece, is selected, and the outer shape is specified. Next, various dimensions such as the outer diameter and the length in the axial direction according to the basic shape pattern are input. Then, when the surface roughness is completely input by an operator or the like, the creation of the n-th stage shape data is completed. Next, as for the (n + 1) th stage, which is the latter stage of the processing of the workpiece, all are input and performed by the worker or the like in the same manner as the above-described procedure.

[Problems to be solved by the invention]

In the conventional device, it is necessary to select the basic shape pattern for each stage on the screen of the CRT display device and input all the shape data related to its external dimensions etc. Needed.
That is, a long time is required for defining the workpiece shape, which increases the entire setup time, which causes a decrease in productivity. Further, there is a problem that there are many erroneous inputs because there are many shape data to be input. The present invention has been made in order to solve the above-mentioned problem, and an object of the present invention is to input shape data of a workpiece in an NC grinding machine or the like with respect to input of shape data input in a previous stage. An object of the present invention is to provide an interactive shape data input device that can reduce the shape data to be input in the subsequent stage as much as possible and shorten the setup time.

[Means for Solving the Problems]

The configuration of the invention to solve the above-mentioned problem is to process a workpiece into a shape consisting of a plurality of steps or similar steps, so that each step has a basic shape pattern, an end face and a cylindrical portion following the end face, a diameter, and an axis. In a shape data input device for inputting shape data such as a dimension in a direction, when setting the shape data of the subsequent stage connected to the former stage, if the former shape data can be used, the former stage copying means for copying the former shape data,
When the former-stage shape data is copied by the former-stage copying means, a joint-shape data setting for setting the diameter of the first-stage cylindrical portion as the diameter data of the second-stage end surface, and setting the first-stage axial dimension as position data of the second-stage end surface. Means for inputting irregular shape data such as irregular dimensions other than the shape data set at the subsequent stage set by the joint shape data setting means.

[Action]

When the shape data of the preceding stage can be used when setting the shape data of the succeeding stage connected to the preceding stage, the preceding stage shape data is copied by the preceding stage copying means. At this time, the connection shape data setting means sets the diameter of the front cylinder portion as the diameter data of the rear end face, and sets the front axial direction as the rear axial position data. Also, the irregular shape data input means inputs irregular shape data such as irregular dimensions in the subsequent shape data which is not set by the connection shape data setting means. As described above, the shape data of the subsequent stage connected to the former stage among the shape data to be processed of the workpiece can be set by the former stage copy processing of the joint shape data setting unit, and only the remaining undefined dimensions and the like are input to the undefined shape data input unit. Then, the input of all the shape data is completed. Therefore, in the case of a workpiece machined into a shape composed of a plurality of steps or similar steps, the setup time can be shortened because the shape data to be input can be extremely small.
