Description

Technical Field

[0001] The invention belongs to the technical field of numerical control machining, and specifically relates to a method for preventing errors in installing and calling a machine tool. Background Art

[0002] As an important production tool for mechanical processing in the manufacturing industry, in recent years, the application scope of CNC machine tools has been continuously expanded, and the processing efficiency and processing accuracy have been continuously improved. Compared with traditional non-CNC machine tools, CNC machine tools can effectively improve product production efficiency and reduce the difficulty of manual operation in dealing with multi-variety small batch parts, high-precision requirements, highly complex structures and frequently modified workpieces. Therefore, CNC machine tool processing is one of the mainstream development directions in the field of mechanical processing in the future.

[0003] In the process of applying CNC machining technology, how to reasonably and effectively utilize the high automation and high efficiency technical characteristics of CNC machine tools, give full play to their ability to process complex parts and realize flexible production, carry out targeted research on auxiliary preparatory work in the CNC machining process, and achieve high utilization of CNC machine tools and high quality of processed parts through standardized operations and software program assistance, while reducing the scrap rate, lowering the frequency of machine tool failures, and preventing the occurrence of safety accidents is of great significance.

[0004] Generally speaking, a complete CNC machine tool processing process mainly goes through three stages, namely, preparation before processing, CNC program execution, and cleaning after processing. Among them, the preparation stage before processing mainly includes the following contents:

[0005] (1) The technician writes the parts processing process documents and CNC processing programs according to the on-site operation instructions;

[0006] (2) The machine tool operator prepares the raw materials and tools for the workpiece according to the process documents;

[0007] (3) Installation of tools, tooling and processing materials: installing tools to the designated tool positions of CNC machine tools, clamping materials to tooling, and installing tooling to the processing table;

[0008] (4) The tool parameters for machining are entered into the CNC system, the tool is loaded onto the machine tool spindle, and the machining program is loaded onto the machine tool through the machine tool human-machine interactive operation interface;

[0009] (5) Inspection of the tool installed on the spindle that is about to execute the machining program.

[0010] As can be seen from the above, there are many preparations before CNC machining and the workload is large. From the preparation of process information to the preparation of machining materials to the installation and testing of tools and tooling, almost all links require manual intervention. Some parameter settings, including the input of tool parameters and the setting of spindle speed multipliers, require manual participation. Due to human errors (such as tool preparation errors, tool loading errors, tool parameter input errors), there are endless problems with the quality and scrapping of machined parts, and damage and scrapping of tools, which have gradually become the main factors affecting the optimization of machined part quality and the improvement of production efficiency. Summary of the invention

[0011] In view of this, the purpose of the present invention is to provide a machine tool tool installation and call error prevention method, which can effectively avoid errors in the tool installation and tool call process caused by human operating errors, thereby avoiding damage to production parts and reducing production accidents and economic losses in the CNC machining process.

[0012] In order to achieve the above object, the present invention provides the following technical solutions:

[0013] A method for preventing errors in installing and calling a machine tool tool comprises the following steps:

[0014] Step 1: Select a processing tool, measure the tool length to obtain the tool length tool set value, measure the tool diameter to obtain the tool diameter tool set value, and measure the bottom angle radius to obtain the bottom angle radius tool set value; and upload the tool set measurement parameters including the tool length tool set value, tool diameter tool set value and bottom angle radius tool set value to the tool error prevention system;

[0015] Step 2: After the tool is installed, identify the number of the tool installed on the machine tool, and compare the identified tool number with the number of the tool to be installed stored in the tool error prevention system; if the comparison is correct, the tool has been correctly installed in the corresponding tool position of the machine tool, and the machine tool continues to run, while obtaining the tool theoretical parameters and remaining tool life stored in the tool error prevention system; otherwise, the machine tool stops running and alarms;

[0016] Step 3: Compare the tool theoretical parameters with the tool assembly measurement parameters; if the comparison result shows that the deviation range of the tool assembly measurement parameters compared with the tool theoretical parameters is within the set tool parameter deviation range, the machine tool continues to run; otherwise, the machine tool stops running and alarms;

[0017] Step 4: Compare the remaining life of the tool with the theoretical time consumption of the machining program; if the life of the currently installed tool is greater than or equal to the theoretical time consumption of the machining program, the machine tool continues to run; otherwise, the machine tool stops running and alarms;

[0018] Step 5: Use the machine tool tool setting instrument to measure the tool to obtain tool measurement parameters including tool length measurement value, tool diameter measurement value and bottom angle radius measurement value, call the theoretical parameters and tool assembly measurement parameters of the tool with the corresponding number stored in the tool error prevention system, and compare the tool measurement parameters with the tool assembly measurement parameters and the tool theoretical parameters respectively; if the deviation range of the tool measurement parameters compared with the tool theoretical parameters is within the set range, and the error range of the tool measurement parameters compared with the tool assembly measurement parameters is within the set range, the machine tool continues to run; otherwise, the machine tool stops running and prompts the tool wear tolerance information on the machine tool human-machine interaction section.

[0028] Among them, L o Indicates the remaining tool life L K Theoretical time consumption of machining program L A The difference between o >0, the machine tool continues to run; otherwise, the machine tool stops running and alarms.

[0029] Furthermore, in step 5, the method for comparing the tool measurement parameters with the tool theoretical parameters is:

[0030] D 1L =|T L -M L |

[0031] D 1D =|T D -M D |

[0032] D 1R =|T R -M R |

[0033] Among them, D 1L Indicates the theoretical value of tool length T L With tool length measurement value M L The deviation between 1D Indicates the theoretical value of tool diameter T D Tool diameter combination value M D The deviation between 1R Indicates the theoretical value of the bottom corner radius T R And the delivery radius tool value M R The deviation between

[0034] If D is satisfied 1L ≤D′ eL , D 1D ≤D′ eD And D 1R ≤D′ eR , the machine tool continues to run; otherwise, the machine tool stops running and alarms;

[0036] Furthermore, in step 5, the method for comparing the tool measurement parameters with the tool assembly measurement parameters is as follows:

[0037] E 0L =|C L -M L |

[0038] E 0D =|C D -M D |

[0043] The beneficial effects of the present invention are:

[0044] The machine tool tool installation and call error prevention method of the present invention is based on the digital processing, identification, storage and comparison of tool parameter information. It realizes tool error prevention during the machine tool tool installation and debugging process by obtaining the tool assembly parameter information (including tool length, tool diameter, bottom angle radius, and tool remaining life) of the tool currently used for processing by the machine tool and the data comparison algorithm. Specifically, by identifying the tool number of the installed tool, reading the relevant information of the tool parameters, and calling the stored tool theoretical parameters and tool assembly measurement parameters for comparison, on the one hand, it is confirmed that the installed tool is the correct tool, and on the other hand, it is confirmed that the tool assembly measurement parameters are within the allowable deviation range of the tool processing compared to the tool theoretical parameters; after the above operations are completed, before the actual processing, through the tool remaining life comparison, it is confirmed that the tool remaining life meets the theoretical time consumption of the machine tool processing program, and then the machine tool tool setting instrument is run to measure the tool to obtain the tool measurement parameters, and by comparing the tool theoretical value with the tool measurement parameters, it is confirmed that the tool is correct. Confirm that the tool measurement parameters are within the allowable deviation range of the processing tool, and confirm that the tool measurement parameters are within the allowable error range of the processing tool by comparing the tool group measurement parameters with the tool measurement parameters; during the actual execution of tool installation and calling, if the data comparison result does not meet the theoretical requirements of the tool parameters for executing the machine tool processing program, the system will prompt relevant deviation information on the human-machine operation interaction interface, automatically alarm and record the corresponding alarm results, update the operation log, and immediately terminate the machine tool program operation, effectively preventing product failures and tool damage caused by incorrect use of tools and incorrect tool parameters.

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0048] like Figure 1The figure is a flow chart of an embodiment of the method for preventing errors in installing and calling machine tool tools of the present invention.

[0061] L0=L K -L A

[0062] Among them, L0 represents the remaining tool life L x Theoretical time consumption of machining program L A If L0>0, the machine tool continues to run; otherwise, the machine tool stops running and alarms.

[0063] Step 5: Use the machine tool tool setting instrument to measure the tool to obtain tool measurement parameters including tool length measurement value, tool diameter measurement value and bottom angle radius measurement value, call the theoretical parameters and tool assembly measurement parameters of the tool with the corresponding number stored in the tool error prevention system, and compare the tool measurement parameters with the tool assembly measurement parameters and the tool theoretical parameters respectively; if the deviation range of the tool measurement parameters compared with the tool theoretical parameters is within the set range, and the error range of the tool measurement parameters compared with the tool assembly measurement parameters is within the set range, the machine tool continues to run; otherwise, the machine tool stops running and prompts the tool wear tolerance information on the machine tool human-machine interaction section.

[0064] Specifically, in this embodiment, the method for comparing the tool measurement parameters with the tool theoretical parameters is:

[0065] D 1L =|T L -ML |

[0066] D 1D =|T D -M D |

[0067] D 1R =|T R -M R |

[0068] Among them, D 1L Indicates the theoretical value of tool length T L With tool length measurement value M L The deviation between 1D Indicates the theoretical value of tool diameter T D Tool diameter combination value M D The deviation between 1R Indicates the theoretical value of the bottom corner radius T R And the delivery radius tool value M R The deviation between

[0069] If D is satisfied 1L ≤D′ eL , D 1D ≤D′ eD And D 1R ≤D′ eR , the machine tool continues to run; otherwise, the machine tool stops running and alarms;

[0071] The method for comparing the tool measurement parameters with the tool assembly measurement parameters is as follows:

[0072] E 0L =|C L -M L |

[0073] E 0D =|C D -M D |

[0078] In this embodiment:

[0079] D eL =D′ eD =E L

[0080] D eD =D′ eD =E D

[0081] D eR =D′ eR =E R

[0082] The specific implementation method of the machine tool tool installation and calling error prevention method of this embodiment is described below with reference to specific examples.

[0083] Now we need to use a plane milling cutter to implement the plane milling (750min) processing steps on the workpiece. After the technician compiles the part processing process file and CNC processing program according to the on-site operation instructions, the machine tool operator prepares the workpiece raw materials and tools according to the process file. Here, we assume that the tool theoretical parameters of the selected plane milling cutter are: tool diameter 200mm, tool radius 30mm, bottom angle radius 3mm; at the same time, select the remaining tool life of 800min, and obtain the tool number. The tool theoretical parameters and tool remaining life can be obtained by identifying the tool number.

[0084] The tool length, tool diameter and bottom angle radius of the tool are measured after the tool is assembled outside the production line to obtain tool assembly measurement parameters including tool length assembly value, tool diameter assembly value and bottom angle radius assembly value, and the tool assembly measurement parameters are uploaded to the tool error prevention system. The tool assembly measurement parameters obtained in this embodiment are: tool length assembly value 200.51mm, tool diameter assembly value 30.32mm, bottom angle radius assembly value 3.00mm.

[0085] Identify the tool installed on the machine tool, compare the tool number obtained by identification with the tool number to be installed stored in the tool error prevention system. If the number comparison is correct, it means that the installed tool is the correct tool. The machine tool continues to run, and compares the tool group measurement parameters of the identified tool with the tool theoretical parameters. Here:

[0086] D 0L =|200-200.41|=0.41mm<D eL =0.55mm

[0087] D 0D =|30-30.32|=0.32mm<D eD =0.45mm

[0088] D 0R =|3-3.00|=0mm<D eR =0.1mm

[0089] The comparison results are all within the allowable deviation range of the tool and the machine tool continues to run.

[0090] Before processing, the machine tool compares the remaining life of the tool with the theoretical time required to execute the machine tool processing program. Here:

[0091] L0=|800-750|=50min>0

[0092] If L0 is greater than 0, execute the tool selection command, call the current tool to the machine tool spindle, and prepare to execute the processing task.

[0093] On the premise that the installed tool has been confirmed to be the correct tool, the tool set measurement parameters are within the allowable deviation range of tool processing, and the remaining life of the tool meets the theoretical time consumption of the machine tool processing program, the tool parameters are actually measured. In this embodiment, the machine tool uses an in-machine tool setting instrument to measure the tool to obtain the tool measurement parameters: tool diameter 199.88mm, tool radius 29.87mm, bottom angle radius 3.06mm, and tool measurement parameters are obtained, and the tool measurement parameters are compared with the tool theoretical parameters. Here:

[0094] D 1L =|200-199.88|=0.12mm<D eL =0.55mm

[0095] D 1D =|30-29.88|=0.12mm<D eD =0.45mm

[0096] D 0R =|3-3.06|=0.06mm<D eR =0.1mm

[0097] The comparison results are all within the allowable deviation range of the tool and the machine tool continues to run.

[0098] On the premise that the installed tool has been confirmed to be the correct tool, the tool set measurement parameters are within the allowable deviation range of tool processing, and the tool remaining life meets the theoretical time consumption of the machine tool processing program, and the tool measurement parameters are within the allowable deviation range of tool processing, the tool measurement parameters are compared with the tool set measurement parameters. Here:

[0099] E 0L =|200.41-199.88|=0.53mm<E L =0.55mm

[0100] E 0D =|30.32-29.88|=0.44mm<E D =0.45mm

[0101] E 0R =|3.00-3.06|=0.06mm<E R =0.1mm

[0102] The comparison results are all within the allowable error range of the tool, so the machine tool continues to run and starts processing.

[0103] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention.
