Description of the Invention: [Technical Field] The present invention relates to the field of CNC machining technology, in particular to a pre-planned graphical interface, according to the size of the workpiece blueprint input product, the tool path can be previewed in advance, the finished product 2D contour and device for automatically generating CNC machining code. [Prior Art] Check that CNC (computer numerical control) machine tool has been widely used in modern machining processes. • The so-called “CNC refers to the use of computer to control the machining path of the tool.” Therefore, before processing, The coordinate points of the machining tool are prepared in advance, and the order of each point is arranged, and the instructions for controlling the auxiliary function switches of the machine tool are appropriately added. The files generated by the process are collectively referred to as a CNC machining program. In order to get the coordinate points that the machining tool will go through, it is necessary to do a lot of calculation according to the blueprint of the workpiece, and the sequence must be carefully arranged. Even if there are only some slight errors, the lighter is only the finished product size. Errors, ♦ severe cases can cause machining tools to hit the workpiece, and even the machine itself causes serious damage. Therefore, the processing industry is gradually adopting the so-called CAM (Computer Aided Manufacturing) system to replace the calculations required for people to prepare CNC machining programs. Orchestration. Most of these CAM systems have been developed in response to the needs of mold processing. Therefore, their functions are mostly to emphasize the ability to process 3D solid surfaces. Because today's computer use human-machine interface is still mostly 2D plane mode (mouse, keyboard and screen), it is difficult to operate intuitively when operating 3D solid surface, usually need to combine several input methods or special mosquito to complete 3D stereo The processing program for the surface. Even if the workpiece has no 3D solid surface, only 201128338 2D(X, Y__)st25D ((x, Y__, z_^^ features, the same operation mode must be used. These (10) systems usually need to be trained due to complicated operation. The person in charge is responsible, and because of its huge system, it must have higher-level computer hardware to execute. Therefore, its application is still limited to the mold processing industry or large-scale processing industry. In addition, there are a few CNC controllers introduced in its control. Simple 2D or 2. 5D CAM software used on the device 'but because it can only be used on the control (4), it can not be used on the computer, so its convenience and flexibility in use are poor. The circular input size produces a CNC machining program. The main purpose of the device is to provide a type of red on the front screen, and to input the red size according to the workpiece blueprint. The invention further aims to provide a device for automatically generating a CNC machining program code according to the size of the workpiece blueprint input. To solve the conventional problem and achieve the object of the present invention. The technical means of the invention is: constructing - a device for generating a CNC code of the code according to the input size of the drawing, which at least comprises: - using the interface to provide a plurality of editing graphic interfaces; and a workpiece contour generating module, Calculate the blueprint size to calculate the coordinate point of the workpiece contour; a tool path pinch generation module to calculate the coordinate point of the workpiece contour; a CNC machining program generation module 'for converting the coordinate value to (10) machining code a tool path pinch preview module for displaying the tool path converted by the CNC machining program code, and a workpiece contour preview module for displaying the workpiece wheel temple changed by the CNC machining program code 201128338; In this way, the size of the finished product can be input according to the workpiece blueprint on the pre-planned graphical interface, so that the contour of the tool path m can be viewed in advance and the cnc processing code can be automatically generated to provide the CNC guarding tool processing path pinch. The invention relates to a device for generating (10) plus jade code according to a face-to-face input size, characterized in that the use interface has a plurality of graphic boundaries pre-planned And the graphic interface is sorted and assigned in advance, and parameters are given. For the data input by the user, _ can be made, and whether the rationality is analyzed, and the user can be informed of the error, and the information edited by the user can be added. Archive, or open the second for editing. In the above (4) - inspection face input income generation (10) processing program mother's device, its ship, the ship can choose a variety of graphical interface through the gift list and according to the processing blueprint In the _ interface, the corresponding size on the blueprint is input into the interface, so that the material surface can judge the reasonableness of the input size, and the size data is sent to the workpiece contour generation module and the tool path health module to calculate the seat. The rank point and the coordinate value, and then the calculated data is converted by the CNC machining program generation module: the code that the CNC controller can understand, and the user selects through the graphic interface, and the preview code is Preview the module surface through the tool path; Age Mei can know in advance whether the input data is completely correct.
