What are the commonly used program modification methods for small cnc machine center?
In the maintenance of a small machining center, you can use a special program to modify some content of a program or a part processing program to detect the function or accuracy of the machine tool. What are the commonly used program modification methods for small vertical machining centers:
1 basic method
1. Single program operation method The maintenance of small vertical machining center involves the operation of the NC program. The maintenance content can generally be carried out by the method of single block operation. Usually use instructions that are connected with the fault to write or modify the existing program for verification and inspection. For example, if you need to check the tool change action, you can use the M06 instruction to write or modify the tool change program in the MDI mode to check the tool change process of a numbered tool in the tool change program operation. ,
2. Multi-associated program operation method As several program segments in the NC program are related to the fault, the multi-associated program operation method can be used, such as using M07, M08 and M09 instructions to compile or modify the program, and check the opening and closing actions of the coolant Process.
1. The dynamic parameter method processing parameter setting I includes spindle speed S, feed speed F, tool compensation, coordinate zero offset, etc., in order to check the machine tool returning to the reference point, rotating speed, feed speed conversion and other actions, it is often necessary to check The operating conditions of the machine tool at various current values can be checked by changing or modifying the processing parameter settings at this time.
2. Program modification method
Methods and steps of using CRT/MDI keyboard to compile and modify numerical control program
①Press the edit button on the operation panel
Or turn the mode switch to EDIT. The edit status indicator turns on, and now it has entered the edit status.
②Press the program key PRGRM on the MD1 keyboard, and the CRT interface will switch to the edit page.
③After selecting a numerical control program, this program is displayed on the CRT interface, and the numerical control program can be edited. Rewrite the program should be Hanren program number 0*...o,’
④Press the PAGE key of the up and down arrow to switch pages, and press the CURSOR direction key t-4 to move the cursor. ⑤When inserting a human character, first move the cursor to the desired pot, and click the number/letter key on the MDI keyboard. Move the code to the city of Yuren, and press the INSERT key to insert the contents of the city Go to the code behind the cursor. For example, when writing and inserting a program segment, move the cursor to the end symbol ";" of the previous program segment. The program segment number, program instruction, etc. that people need to challenge in Yuren Pohan people, use the INSERT key to input one by one. Human domain content insertion program.
⑥When you need to cancel the data in the boxer city, press the N key to cancel the data in the boxer city. The order of cancellation is that the last pleasant character is deleted first. When deleting the characters in the program, first move the cursor to the position of all the characters, and press the DELETE key to delete the code where the cursor is.
⑦When you need to find the letter or code in the program, draw in the letter or code that Chenghan people need to search; press the search chain to start the search after the cursor is located in the current CNC program. The searched code can be a letter or a complete code. For example: "N00I O", "M" and so on. If there is a searched code in this numerical control program, the cursor stays at the found code; if there is no searched code after the cursor position in this numerical control program, the cursor stays at the original position.
⑧When you need to replace the character at the cursor. First move the cursor to the position of the character to be replaced, and input the replaced character into Gunman City through the MDI keyboard, and press the replace key ALTER. Replace the contents of the box with the contents of the cursor. .
