How to operate the editing of a new program on a machining center

The core operation logic for editing new programs in machining centers is universal, and the basic steps of different mainstream systems are basically the same. The following is the complete operation process:

Ⅰ. Preparatory Work and Mode Switching

Switch editing mode ‌ : Align the machine tool's working mode knob with "EDIT", and confirm that the editing status indicator light is on to avoid accidental touches that may cause safety accidents.

Preliminary parameter confirmation ‌ : In advance, based on the shape, material, and precision requirements of the parts to be processed, preset the basic processing parameters such as the spindle speed and feed rate to ensure smooth programming in the subsequent stage.

Ⅱ. Create a new program file

to enter the program list ‌ : Press the corresponding key of the system to enter the program management interface. For Frank system, press the "PROG" key. For Mitsubishi system, after entering the editing mode, select the corresponding soft key. For the new generation system, directly enter the programming mode.

Enter the program name ‌ : For frank systems, the program number should start with the letter "O" (e.g., O0012). For other systems, enter the legal program name as per the standard, avoiding the system protection section from 8000 to 9999. After confirmation, a blank new program will be generated.

Ⅲ. Program Content Editing

Input instruction codes ‌ : Use the numeric and alphabetical keys on the control panel to input processing instructions such as G codes and M codes. Each line of code ends with a semicolon. Press the "INSERT" key to insert characters and the "DELETE" key to delete incorrect content.

Adjust detailed parameters ‌ : According to actual processing requirements, modify parameters such as cutting depth, tool path speed, and tool path. Alternatively, copy general instruction fragments from existing mature programs, paste them into new programs, and then make targeted adjustments.

Ⅳ. Saving and Debugging Verification

Save program ‌ : After all the content is edited, press the "INPUT" or "CALC" key to confirm saving and store the new program in the machine tool controller.

Simulation and debugging ‌ : First, start the machine tool simulation operation function to check if there are any coordinate deviations, parameter mismatches or other issues in the program. After confirming that there are no syntax errors or logical loopholes, proceed with the trial cutting process.

Ⅴ. Key Points of Specialized Operations for Different Systems

Frank system ‌ : Program naming is mandatory to start with "O". You can directly enter the new program serial number in the program directory and click Create, which is highly convenient to operate.

Mitsubishi system ‌ : Supports advanced editing functions such as string marking, specified line number jumping, and batch program transmission, making it suitable for rapid modification and verification of complex programs.

New-generation system ‌ : Basic information such as the workpiece coordinate system and tool compensation needs to be set in advance. After editing, it should be verified in the simulation environment first to avoid conflicts with functions such as automatic tool changing.
