Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] figure 1 It shows the flow chart of generating the thread milling macro program code according to the embodiment of the present invention, including: inputting the tool position file, which includes the technological parameters of the thread milling macro machining; analyzing the tool position file to obtain trajectory data; converting the trajectory data code for the macro program.

[0024] Specifically, the circular arc of thread processing is given, and the corresponding process data is prepared. Define the beginning and end of the variable and cycle definition of the program code, and output the parameters of the helical trajectory (pitch, thread length, direction of rotation, internal or external thread, etc.) into a macro program code according to the format requirements. In the macro program code, use the macro variab...

Abstract

The invention provides a method for generating a thread milling macro-program code, which comprises the following steps: inputting a cutter location file which comprises technological parameters of macro-thread milling; resolving the cutter location file to acquire track data; and converting the track data into the macro-program code. The method solves the problems of low efficiency, time wasting and easy occurrence of errors of manual coding and the problem that CAM software cannot generate the macro-program code, and achieves the effects of reducing error rate, improving efficiency and saving manpower.

Description

technical field [0001] The invention relates to the field of numerical control, in particular to a method for generating macro program codes for thread milling. Background technique [0002] As an important means to ensure product quality, improve labor productivity and realize automation, CNC machining is widely used in various manufacturing fields such as automobiles, aviation, and molds. Whether the CNC machine tool can give full play to its role depends on the efficiency and ease of use of the CNC program it uses. In actual production, there are many parts with similar structures and different sizes. If each batch of parts is programmed for NC machining, a lot of time will be wasted. Making full use of macro programs is a very effective measure to solve these problems. Instructions including functions such as variable, direction, comparison and judgment are called macro instructions, and programs including macro instructions are called macro programs. For programs tha...
