[0002] Currently, conventional lathes manage each tool individually, requiring replacement after use. Due to differences in the parts being machined, the tool's lifespan varies, necessitating frequent tool replacements for tools requiring high precision or those that wear out quickly, impacting machining efficiency. Implementing this through program editing is also very complex. Furthermore, tool wear cannot be monitored in real-time; it's only detected when measuring the workpiece, leading to uncontrollable defects in the finished product. Summary of the Invention

[0016] To more clearly describe the technical content of the present invention, the following description is provided in conjunction with specific embodiments.

[0017] The present invention provides a method for life group management of cutting tools on a lathe, comprising the following steps: (1) Set the tool group and tool life; (2) Inspect the wear condition of the cutting tools; (3) If the tool wears out, it will automatically replace other tools in the same group; otherwise, it will continue to process.

[0018] In a preferred embodiment of the present invention, step (2) specifically includes the following steps: (2.1) Set the tool load and its acceptable range; (2.2) During the machining process, record the torque of each axis; (2.3) After machining is completed, compare the torque and wear range. If the torque of each axis is within the acceptable range, the tool does not need to be replaced; otherwise, the tool is worn.

[0019] In a preferred embodiment of the present invention, step (2.1) specifically comprises: In learning mode, perform a normal machining operation, record the tool load, and set the upper and lower torques for wear and the torque at the time of failure based on the learned values.

[0020] In a preferred embodiment of the present invention, the automatic replacement of other tools in the same group in step (3) specifically includes the following steps: (3.1) Obtain the tools within the group; (3.2) Obtain information on tool usage; (3.3) Locate an old, usable tool. If found, proceed to step (3.5); otherwise, proceed to step (3.4). (3.4) Locate a new tool. If found, proceed to step (3.5); otherwise, issue an alarm. (3.5) Using the found cutting tools, the tool life is increased.

[0021] The present invention provides an apparatus for life group management of cutting tools on a lathe, wherein the apparatus includes: A processor is configured to execute computer-executable instructions; The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the steps of the method described above for life group management of cutting tools on a lathe.

[0022] The processor of the present invention for implementing life group management of cutting tools on a lathe is configured to execute computer-executable instructions, which, when executed by the processor, implement the various steps of the above-described method for implementing life group management of cutting tools on a lathe.

[0023] The computer-readable storage medium of the present invention stores a computer program thereon, which can be executed by a processor to implement the various steps of the above-described method for life group management of cutting tools on a lathe.

[0024] This invention provides a method for managing multiple tools in a group on a conventional lathe, automatically switching between other tools within the same group, so that the tool lifespan reaches its end almost simultaneously, eliminating the need for frequent tool replacements.

[0025] During the machining process, the torque feedback of the motor can be detected to determine the wear condition of the cutting tool. Once tool wear is detected, other tools in the group will be automatically replaced, and a message indicating that the tool has worn out will be displayed on the corresponding interface.

[0026] An alarm will sound when all tools in the same group become unusable, minimizing the number of defective products caused by untimely tool switching. This improves processing efficiency and reduces waste.

[0027] Tool group management: tool switching when the tool life of a tool in the same group reaches its limit or the torque exceeds its limit; tool load detection is also included in the tool life.

[0028] The present invention employs the following measures: Tool group and life setting. This invention provides a dedicated interface for setting tool group and tool life, allowing users to configure tool life and group settings, such as... Figure 1 As shown.

[0029] Tool wear detection. This invention provides an interface setting where, during a normal machining cycle in "Learning" mode, the tool load is recorded. Based on this learned value, the upper and lower torque limits for wear and the torque at which failure occurs are set. Subsequently, in "On" mode, the feedback and set ranges of the torque for each axis are automatically compared to manage their service life. The torque of each axis is also displayed after each machining operation, such as... Figure 2 As shown.

[0030] When changing tools, switch tools within the same group based on tool life and wear. Use Txx to determine the group.

[0031] In a specific embodiment of the present invention, The present invention automatically switches between tools in the same group. The specific operation steps are as follows: 1. Set the tool group and its lifespan; 2. Edit Txx; 3. Locate usable knives within the same group; 4. Change the cutting tool.

[0032] The present invention performs load detection, and the specific operation steps are as follows: 1. Set the tool load and its acceptable range; 2. Record the torque during the processing; 3. After processing is completed, compare the processing records with the acceptable range to determine the wear condition.

[0033] The acceptable range refers to the learning value of the axis load during a single machining operation controlled by the T-code (tool number). Users can set reasonable lower wear limits, upper wear limits, and damage values ​​based on these learning values. Internally, the system considers values ​​below the upper wear limit to be acceptable, indicating a tool suitable for machining. Furthermore, to prevent a large motor torque immediately upon tool contact with the workpiece, exceeding the upper wear limit but not the damage value is permissible.

[0034] This technical solution groups the cutting tools and provides a switching process for tools within the same group after the lifespan of a single cutting tool is reached.

[0035] This technical solution incorporates motor torque judgment into the condition determination process, and allows for the switching of other tools of the same type within the same group after the tool's service life has expired.

[0036] This technical solution also involves the workpiece side when detecting torque feedback. If the motor movement torque on the workpiece side exceeds the normal value during machining, it can also indicate the tool life limit. This technical solution also includes a tool switching process within the same group after the lifespan of a single tool has expired.

[0037] Setting the tool group and its lifespan also includes the following steps: Users can set the T-code (tool number) and its corresponding group number, as well as the current lifespan and maximum lifespan of each tool. During use, tools of the same type should have the same group number, and each tool should have a different T-code.

[0038] If a tool wears out, it will automatically replace other tools in the same group. This process includes the following steps: After executing the tool group number command, the tools in the group will be inspected. Older, undamaged tools will be used first, followed by new, unused tools. Damaged tools will be automatically skipped until all tools are worn out.
