[0082] The technical solution of the present invention (including the preferred technical solution) is further described in detail below by means of the accompanying drawings and by listing some optional embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0083] Example 1

[0084] like Figures 1 to 5 As shown, the three-in-one drive housing virtual processing simulation method provided in this embodiment includes the following steps:

[0085] Step S101: Acquire machining center component data and create a three-dimensional machining center model.

[0086] In this embodiment, the data of machining center parts are obtained, and the machining center parts data includes the structural dimensions and spatial layout of the parts such as the machining center base, column, saddle, spindle, A or B or A+B or B+A rotating axis and tool magazine. Due to equipment confidentiality, the equipment manufacturer does not provide a three-dimensional machining center model of the whole machine. The acquisition method can be on-site surveying or the equipment manufacturer provides the external structure and dimensions of the parts (no detailed internal structure and dimensions are required).

[0087] Creating a 3D machining center model involves using 3D modeling software to create 3D models of each component of the machining center from on-site surveying or machining center component data provided by equipment manufacturers, and assembling them into a complete 3D model of the machining center according to the actual layout.

[0088] It should be noted that the created 3D machining center model matches the actual machining center, including:

[0089] a) The spindle structure and the shape and size extending outside the protection in the 3D model are completely consistent with the actual machining center;

[0090] b) The structure and dimensions of the rotating axis turntable in the 3D model are completely consistent with the real object;

[0091] c) The size of the processing area in the 3D model is exactly the same as the actual object.

[0092] Step S102: establishing a virtual motion relationship of the three-dimensional machining center model.

[0093] In this embodiment, the virtual motion relationship of the three-dimensional machining center model is established, including the virtual motion relationship of the spindle rotation, the motion axis movement, the rotation axis rotation and the tool magazine tool change. Specifically, it includes:

[0094] Create and configure tool mounting, minimum and maximum rotation speeds on the spindle;

[0095] Create and configure the mechanical zero position, movement direction, travel size and maximum movement speed of the motion axis;

[0096] Create and configure the mechanical zero position, rotation direction, stroke size and maximum rotation speed of the rotary axis;

[0097] Create and configure tool change positions, tool change methods, and tool change speeds.

[0098] That is to say, the virtual motion relationship includes spindle rotation, motion axis (X / Y / Z axis) movement, rotation axis (A / B / A+B / B+A axis) rotation and tool magazine tool change. The specific implementation includes:

[0099] a) spindle rotation including tool installation on the spindle, creation and configuration of minimum and maximum rotation speeds;

[0100] b) the movement of the motion axis (X / Y / Z axis) includes the creation and configuration of the mechanical zero position, movement direction, stroke size and maximum movement speed of each axis;

[0101] c) the rotation of the rotating axis (A / B / A+B / B+A axis) includes the creation and configuration of the mechanical zero position, rotation direction, stroke size and maximum rotation speed of the rotating axis;

[0102] d) The tool magazine tool change includes the creation and configuration of the tool change position, tool change method and tool change speed.

[0103] Step S103: developing a CNC system post-processor, which can convert the machining data generated in the programming environment into a CNC program suitable for an actual machining center;

[0104] In this embodiment, different types of post-processors are developed for different types of machining centers. The functions of the dedicated post-processors include:

[0105] a) The tool path for part machining compiled in the 3D programming environment is automatically generated into an NC program through a dedicated post-processor. The structure and format of the NC program are completely applicable to the established machining center and can be used directly;

[0106] b) NC programs that are automatically written, manually written, or copied from a machining center, in the corresponding virtual machining center environment, drive the virtual machining center's spindle, moving axis, rotating axis, tool magazine, etc. to move relative to each other through a dedicated post-processor to achieve virtual machining simulation of the NC program.

[0107] Step S104: Perform virtual machining simulation using the three-dimensional machining center model, virtual motion relationship and converted NC program to verify the correctness of the machining program, tool path and machining process.

[0108] The virtual machining simulation includes the following steps:

[0109] a) Compile NC program, automatically or manually compile NC processing program for three-in-one drive housing, the program format is consistent with the actual process format;

[0110] b) Create three-dimensional models of tools, auxiliary tools and fixtures, with the structure and dimensions consistent with the real objects;

[0111] c) Install the workpiece and correctly install it in the fixture of the virtual machining center. The installation and positioning position should be consistent with the real object;

[0112] d) Import NC program, import NC machining program into the numerical control system of the virtual machining center;

[0113] e) Virtual machining simulation: set simulation interference, workpiece 3D material removal and machine tool status display, etc. to perform virtual machining simulation of workpiece.

[0114] For example Figure 1 As shown, the process of the present invention includes:

[0115] a) Development of virtual machining environment, including: 3D modeling of machining center, establishment of motion relationship of each moving component and configuration of virtual machining environment, so as to transform the static 3D model into a moving virtual machining center.

[0116] b) Virtual control system development, including: post-processor development, virtual CNC system configuration. After configuration, it is equivalent to installing a brain in the virtual machining center, which can convert tool paths, recognize G codes, M codes and macro programs in NC programs, etc.

[0117] c) Virtual machining preparation, including: 3D drawing of the machined part, blank drawing, 3D drawing of the fixture, 3D model of tooling and auxiliary tools, NC machining program and machining tool path.

[0118] d) Virtual machining simulation, including: NC program virtual machining, machining process interference check, machining time statistics and related process file output, etc. After the NC program simulation is correct, it can be directly sent to the workshop for actual cutting, and the correctness of the NC program and the debugging risk will be greatly reduced.

[0119] For example Figure 2 As shown in the figure, this model is a five-axis virtual machining center model of A+B axis. The three-dimensional modeling of the machining center is to create a three-dimensional machining center model based on the machining center used in the workpiece processing process, surveying and mapping, or obtaining the machining center parts data from the equipment manufacturer. The model data includes but is not limited to: machining center base assembly, X-axis assembly, Y-axis assembly, Z-axis assembly, A-axis (or B-axis or A+B-axis or B+A-axis) assembly, spindle and tool magazine assembly. The structural form and spatial layout of each component must match the actual machining center. The difference in the model will directly affect the virtual simulation effect.

[0120] Figure 3 The embodiment of the present invention provides a method for establishing a motion relationship of a virtual machining center. Before the components of the A+B axis five-axis three-dimensional machining center model have established their motion relationship, the NC program cannot drive the virtual machining center to move. The specific steps of establishing the motion relationship of the virtual machining center include:

[0121] a) Clarify the motion relationship. The virtual machining center has three main motion directions: the worktable motion side, the spindle motion side, and the tool magazine motion side. Worktable motion side: The worktable is equipped with an A-axis turntable, the A-axis is equipped with a B-axis turntable, and the fixture and workpiece are installed on the B-axis turntable. They are uniformly driven by the Z-axis and move together. In addition to moving simultaneously with the Z-axis, the A-axis and the B-axis also rotate around the X-axis and the Y-axis respectively. Therefore, when establishing their motion relationship, they should be built according to the subordinate relationship between them. Spindle motion side: The column is installed on the base of the machining center, the X-axis is installed on the main column, the Y-axis is installed on the X-axis, and the spindle is installed on the Y-axis. The spindle movement is driven by the X-axis and the Y-axis separately. The X-axis drives it to move left and right, and the Y-axis drives it to move up and down. Therefore, when establishing its motion relationship, it should also be built strictly according to the subordinate relationship between them. Tool magazine motion side: The main function of the tool magazine is to install all the tools required for workpiece processing. During the processing, the tool magazine rotates to pre-select tools, call tools, and realize tool exchange between the tool magazine and the spindle through the robot arm. Its movement relationship is the rotation of the tool magazine and the up and down movement of the tool cylinder when changing tools.

[0122] b) Create a movement, according to Figure 3 The motion relationship shown is created in three lines in sequence:

[0123] 1) The motion components, mechanical zero position, moving direction, stroke size and maximum moving speed of the X-axis, Y-axis and spindle.

[0124] 2) The motion components, mechanical zero position, moving direction, rotation direction, stroke size and maximum moving speed of the Z-axis, A-axis and B-axis. During processing, the workpiece and fixture are installed on the B-axis, so the installation position of the fixture must also be set on the B-axis.

[0125] 3) The motion components of the tool magazine and tool changing robot, mechanical zero position, moving direction, rotation direction, stroke size and maximum moving speed.

[0126] Figure 4 This is the operating principle of the virtual machining postprocessor provided by the embodiment of the present invention. The postprocessor is the core unit of the virtual machining center. It is a processing program that includes the machining center and its control system, which is equivalent to the CNC system of the actual machining center. Postprocessing is one of the key technologies of CNC machining programming technology and a necessary prerequisite for CNC machining and virtual simulation. It needs to be developed specifically according to the type of CNC system of the actual machining center, and is usually called a dedicated postprocessor. The specific implementation includes the following:

[0127] a) The tool path for part machining compiled in the 3D programming environment is automatically generated into an NC program through a dedicated post-processor. The NC program structure and format are completely applicable to the actual machining center and can be used directly without modification;

[0128] b) NC programs that are automatically written, manually written, or copied from a machining center, in the corresponding virtual machining center environment, drive the virtual machining center's spindle, moving axis, rotating axis, tool magazine, etc. to move relative to each other through a dedicated post-processor to achieve virtual machining simulation of the NC program.

[0129] Figure 5 It is a virtual machining simulation application provided by an embodiment of the present invention. During the virtual machining simulation process, once interference between the spindle and the fixture, the spindle and the workpiece, the tool and the fixture, the tool and the workpiece, or code errors or coordinate value errors in the NC program are found, the simulation system can display them in the form of an alarm, making it convenient for the technician to optimize the process and modify the NC program. The application of virtual machining simulation is specifically embodied as follows:

[0130] a) Verify the correctness of NC programs and product design in advance;

[0131] b) Simulate processing time and verify the processing performance of equipment, and rationally plan the process plan;

[0132] c) Improve the accuracy of tooling and fixture design;

[0133] d) Inspection of interference during machining to avoid collisions during machining, and the cost of repurchasing or repairing tools, fixtures, and machine tool damage caused by collisions during debugging and program adjustment;

[0134] e) Significantly shorten product on-site debugging time, shorten product manufacturing cycle, and ensure on-time delivery of products.
