Description

Technical Field

[0001] The present invention relates to the technical field of machining of construction machinery, and particularly to a macro program modular programming method based on the FANUC system. Background Art

[0002] With the diversification and new energy of construction machinery products, the product structure will be continuously improved and updated after market use verification. In order to better meet the needs of users to experience high-end products as early as possible, manufacturing enterprises will require that from the drawing design, process preparation to the actual production process, the shorter the production cycle, the earlier one can enter the testing stage, the earlier one can improve, and the earlier one can be put on the market. Therefore, the pressure is on the manufacturing department. However, the programming capabilities of on-site machining operators vary, programming is time-consuming and laborious, and production efficiency is low. How to provide a set of standardized programming methods is an urgent problem to be solved. Summary of the Invention

[0003] Object of the Invention: The object of the present invention is to provide a macro program modular programming method based on the FANUC system.

[0004] Technical Solution: The present invention includes making general templates for common machining processes such as reciprocating milling of plane, dynamic milling of hole, helical milling of hole, milling of outer circle, milling of equally divided circumferential holes, milling of polygon, milling of rectangular groove, milling of internal and external threads, milling of groove, and chamfering of hole opening. One only needs to change the parameters therein according to the instructions and call the corresponding macro program number to achieve rapid programming.

[0005] Further, the production of the general template includes first clarifying the independent variable parameters, operation instruction types, conditional expressions, operation order, and call parameter descriptions of the FANCU system, and then making modular usage scenarios.

[0006] Further, the milling of the plane is controlled by parameters such as the length and width of the given plane, the safe plane for tool entry, the tool diameter, the starting point of the cutting plane, the end point of the cutting plane, the step distance, the cutting depth per layer, and the cutting speed.

[0007] Further, the starting position for measuring the milling of the plane is the specified safe plane and the cutting starting point.

[0008] Further, the parameter description of the milling of the plane includes:

[0009] Given the S parameter, S is the step distance, which is between 0.6 and 0.9 of the tool diameter and does not exceed 1 at most;

[0010] Given the Q parameter, Q is the cutting amount per layer, which is between 0.5 and 1.2 and is determined according to different materials and tool performances;

[0011] Given the F parameter, where F is the feed rate, which is determined according to the cutting amount per layer and the material properties, and should also be within the maximum cutting force of the machine tool.

[0012] Furthermore, the dynamic milling of holes is parameter-controlled by specifying the hole milling diameter, hole milling depth, spiral plunge diameter, tool diameter, starting point of the cutting plane, cutting depth per segment each time, lateral step, cutting depth per layer, and cutting speed.

[0013] Furthermore, the starting position for measuring the dynamic milling of holes is the specified cutting start plane parameter.

[0014] Furthermore, the description of the dynamic milling of holes parameters includes:

[0015] Given the C parameter, where C is the spiral milling diameter, with a maximum of 2 times the tool diameter - 1 and a minimum of 1 times the diameter + 1;

[0016] Given the Z parameter, where Z is the cutting depth per segment each time, less than or equal to the effective cutting edge length of the tool and less than or equal to the hole milling depth;

[0017] Given the S parameter, where S is the lateral step, ranging from 0.1 to 0.15;

[0018] Given the Q parameter, where Q is the cutting depth per layer, ranging from 0.5 to 0.8.

[0019] Furthermore, the spiral milling of holes is parameter-controlled by specifying the center coordinates of the hole, hole milling diameter, tool diameter, starting point of the cutting plane, end point of the cutting plane, cutting depth per layer, and cutting speed parameters.

[0020] Furthermore, the description of the spiral milling of holes parameters includes:

[0021] Given the XY parameter, which is the center coordinates of the hole milling; given the A parameter, where A is the hole milling diameter; given the D parameter, where D is the tool diameter, less than the hole diameter of the hole milling; given the Z parameter, where Z is the end coordinate of the hole milling; given the Q parameter, where Q is the cutting depth per layer, ranging from 0.5 to 0.8; given the F parameter, where F is the cutting speed.

[0022] Beneficial effects: Compared with the prior art, the present invention has the following remarkable advantages: When programming for the same machining process requirements, there is no need to start editing from scratch. By inputting the corresponding parameters, the program can be called, simplifying the programming, avoiding programming errors, improving production efficiency, and the efficiency is increased by more than 80%.

[0030] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] The present invention includes the following steps: making the common machining processes such as reciprocating milling plane, dynamic milling hole, helical milling hole, milling outer circle, milling equally divided circumferential holes, milling polygons, milling rectangular grooves, milling internal and external threads, milling bevels, and hole chamfering into a general template. Just change the parameters therein according to the instructions and call the corresponding macro program number to achieve rapid programming.

[0032] The production of the general template includes first clarifying the independent variable parameters, operation instruction types, conditional expressions, operation sequence, and call parameter descriptions of the FANCU system, and then making modular usage scenarios.

[0033] For example: a large plane with a length × width of 2000 × 1000 needs to mill the upper surface, and a φ160 rough surface milling cutter is selected.

[0034] It can be quickly realized by calling the macro program O8401, and the program writing is as follows:

[0035] G65P8401A2000B 1000C50D 160E5Z0S0.85Q0.85F2000. For subsequent workpiece changes and re-milling the surface, only change the A and B parameters. The path generated by the program is as Figure 1 shown.

[0036] Such as Figure 2 , 3 , and 4 shown. Before the modular programming of writing the macro program, the independent variable parameters of the FANCU system ( Figure 2 ), operation instructions ( Figure 3 ), conditional expressions (such as 4), operation sequence, and call parameter descriptions should be very clear.

[0037] After the above parameters and arithmetic symbols are clear, modular usage scenarios can be created. Common machining usage scenarios include face milling, dynamic hole milling, helical hole milling, milling internal and external threads, chamfering the hole opening with a C angle and an R angle, milling polygons, milling slots, milling slope edges, etc. The following will explain the process instructions for face milling, dynamic hole milling, and helical hole milling:
