Abstract

PURPOSE:To omit the correction of a working process done by an operator and to select an optimum tool by dividing a working area into the areas corresponding to plural working processes and at the same time selecting a tool having the same shape as the tool that is used for dividing the working area. CONSTITUTION:A unworked shape data SB inputted from a keyboard 1, a data input part 2, an input data separating part 3, is divided each process by an unworked shape dividing part and goes to a process-based unworked shape data SE. The data SC is stored in a process-based unworked shape storing part 6. In the same way, the process-based worked shape data SE is stored in a process-based worked shape storing part 9. Meanwhile a shape having the same shape as the tool that is used for dividing the working area is selected out of a tool data storing part 19 regardless of the tool selecting order data. Then an undefined tool data generating part 22 produces the tool data on the tool length, etc., for each divided area, and the process-based tool data SF is stored in a process-based tool data storing part 10. Thus it is possible to produce the numerical control information for selection of an optimum tool in accordance with the contents of those parts 6, 9 and 10 with no correction of the working process done by an operator.

Figures 4 (B) and (C) are diagrams showing the tools used in the respective)J loe processes. This requires an unrealistic tool (with a large insertion angle).

(Problems to be Solved by the Invention) By the way, as the above-mentioned conventional numerical control information creation device, there is a device disclosed in Japanese Patent Application Laid-Open No. 127947/1989, “Tool Selection Method in Automatic Programming”. As mentioned above, the creation of the pre-machining shape and the post-machining shape of the tool surface for each C process is done by the operator dividing the pre-machining shape data and the post-machining shape data, respectively, and the automatic fishing is performed based on the divided results. Therefore, even if the shape can be machined using a target tool by dividing into multiple machining processes, an inexperienced operator may recognize it as a single machining process or divide it into multiple machining processes. However, in many cases, the tool is divided into shapes that cannot be machined without using a special tool, and there is a problem in that the tool information selected for each machining process must be frequently corrected.

The present invention was inspired by the above-mentioned circumstances, and it is an object of the present invention to provide a numerical control information creation device that does not require an operator to modify a machining process and can select an optimal tool.

(Means for Solving the Problems) The present invention relates to a numerical control information creation device that inputs a shape upon completion of machining and a shape before machining, and creates numerical control information based on those shapes. The above object of the present invention is to provide a tool information storage means in which tool information including at least the insertion angle of the tool into the workpiece is stored; and a dividing means for dividing into regions corresponding to processing steps, and the numerical control information is achieved by creating the numerical control information based on the regions corresponding to the processing steps divided by the dividing means. The tool information storage means stores tool information including information indicating the type of machining process in which the tool is used as well as the insertion angle of the tool; This is achieved by providing a tool information selection means for each process for selecting a tool for each machining process from the storage means.

(Function) In the present invention, based on the standard tool shape or the pre-registered tool shape, the machining area expressed as the difference between the shape at the completion of machining and the shape before machining is divided into multiple machining steps. By dividing the machining area into corresponding areas and selecting a tool with the same shape as the tool used to divide the machining area, it is possible to generate a machining process according to the tool, and also to create the optimal machining process suitable for the machining process. You can choose the tools.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram of an embodiment of the J-117 report creation system according to the present invention, and the same components as those in the conventional system are given the same reference numerals and the explanation thereof will be omitted.

In the figure, in the present invention, a tool data storage section 19, a tool selection order data storage section 20. Tool data selection section 21 for each process
and an undefined tool data generation section 22 are newly added. Therefore, the tool data storage unit 19 inputs and stores tool data including information indicating the insertion angle of the tool into the workpiece and the type of machining process in which the tool is used from the input data separation unit 3. The tool selection order data storage section 20 has tool selection order data for the same machining process type. The tool data selection unit 21 for each process includes a tool selection order data storage unit 2.
Tool data is selected from the tool data storage section 19 based on the tool selection order data stored in .

The undefined tool data generation unit 22 generates input tool data from among the tool data used to divide the machining region input into the pre-machining shape division unit 5 and the post-machining shape division unit 8 into regions corresponding to a plurality of machining steps. Items that are not included, especially the length of the tool and the thickness of the tool, the shape before machining SC for each process and the shape S after machining for each process
E and stores it in the tool data storage unit 10 for each process as tool data for each process SF.

In addition, if tools that can be used for multiple machining process types are selected in the tool data selection unit 21 for each process with priority over the tool selection II data, the same tool can be prioritized even if the machining processes are different. You can reduce the number of tools you use. Furthermore, by changing the machining conditions depending on the length of the tool and the diameter of the tool in the numerical control information creation section 14, the machining conditions can be made to match the machining process and the tool. Figure 2 (A) is a diagram showing an example of the division of machining processes determined in this way, and Figures 2 (B) and (C) are diagrams showing the tools selected for each machining process. be.

Here, in the example shown in FIG. 2, the machining process is generated based on tool data having at least the insertion angle of the tool into the workpiece, which is registered in advance for the machining process in the outer diameter longitudinal direction.
The outer diameter and processing steps that can be processed using the registered tool are created. Therefore, in addition to the end face processing step (cylindrical portion) and the outer diameter longitudinal direction processing step (black section), an outer diameter longitudinal reverse direction processing step (11111 parts) is required. Therefore, if the tool W & R for the outer diameter longitudinal direction machining process is also registered for the end face machining process, the same tool can be used for the outer diameter longitudinal direction machining process by giving priority to the same tool and selecting "C". It can also be used in the end face machining process, reducing the number of tools used.

(Effects of the Invention) As described above, according to the numerical control information creation device of the present invention,
Based on the standard tool shape or pre-registered tool shape, the machining area, which is expressed as the difference between the shape at the completion of machining and the shape before machining, is divided into regions for multiple machining processes, and the machining area is further divided into regions for multiple machining processes. By selecting a tool that has the same shape as the tool used when dividing, it is possible to generate a machining process that matches the tool, and also to select the most suitable tool for the machining process, making it easier for the operator to control the machining process. No modification is required and the most suitable tool can be selected. Furthermore, if the same tool is registered so that it can be used in different machining processes, the number of tools used can be avoided by preferentially selecting the same tool.
