Description

Group cutter function for machining center

Technical Field

The invention relates to the field of numerical control machining, in particular to a group cutter function for a machining center.

Background

The numerical control machining center plays a role in lifting weight in an automatic production line, and the important component of the numerical control machining center manages the tools produced by a machine tool, so that the numerical control machining center is a key step for realizing the automatic production line. Generally, a product is often processed by a plurality of processes, so that a plurality of processing tools are also needed, and the service life of the tool is consumed in the processing.

The service life of the cutter mainly refers to the service life of the cutting tools, the time for which each cutting tool can process is determined, and after a certain number of workpieces are processed and the cutter fails, a new cutting tool needs to be replaced. Wherein, the consumption life of the same cutting tool is different when cutting different workpieces, the consumption life is different in different procedures, one cutting tool fails after processing a certain number of workpieces, if the cutting tool is not replaced with a new cutting tool in time and is continuously used, the processed product is bad, therefore, the normal use and the production efficiency of the machine tool can be directly influenced by managing the service life of the cutting tool,

in the management, in order to master the service life of the cutting tool, an on-site operator often checks the wear state of the cutting tool after each machining to determine whether the service life of the cutting tool is reached, which is time-consuming, labor-consuming and has considerable error, so that an electronic system is generally used for managing the service life of the cutting tool.

The tool life management function provided by the system on the market at present generally only supports the life counting, timing and counting of each tool, and the tool numbers in each tool magazine do not have an internal connection function, so that after the current tool life is reached, only the tool can be replaced for processing, but the new tool cannot be counted according to the original tool service life, time and labor are wasted, and the tool is inconvenient to use.

In addition, when a machine station continuously processes batch workpieces, multiple cutters are often needed for processing the same workpiece to be processed, and each cutter has a specific service life, so that cutters with the same specification can be placed in a cutter magazine, and after the current service life of the cutter number is up, the original process of cutter number changing processing is manually carried out by setting a new cutter number in a program in advance, and the same cutter number in the cutter magazine cannot be automatically searched for processing.

In addition, although the shapes of the same kind of tools are the same, the clamping length of each tool length cannot be guaranteed to be the same when the tools are mounted, that is, the tool length of each tool has slight difference, and after the same tool number is called, the tool lengths of the tool numbers need to be debugged at the same time, so that the machining accuracy can be guaranteed.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 schematically shows a tool life management page for a group blade function of a machining center according to an embodiment of the present invention, and fig. 2 shows a machining status page for the group blade function of the machining center in fig. 1.

The method of use of the group blade function is described below as simulated and illustrated, with the specialized download being simulated using the W32 22MA 10.118.52S simulator.

First, the simulator is turned on, then the controller parameters are modified, the simulator is restarted, and a MACRO (MACRO) is imported.

The modified controller parameters are Pr3228, pr4601 and Pr3701, wherein the Pr3228 is the on-cutter management function parameter, 0 is off, 1 is on, and the on-cutter management function parameter is modified to Pr3228=1; pr460 is a service life management function parameter for starting a new version of cutter, 0 is an old version, 1 is a new version, and the service life management function parameter is modified into Pr4601=1; pr3701 is G code call macro entry table number 1, which is modified to Pr3701=8, indicating that G43 is enabled.

The steps of the imported macro are as follows: f2 Programming-F8 archive management-F4 imports macros G43 and T0000.

Then, a tool life management page of the simulator is opened, and the specific operation is F3 offset setting-F2 tool setting-F7 tool life management, and relevant parameters are set.

As shown in fig. 1, the tool life management page displays parameters such as the number of tools, group, tool management, current count, warning life, maximum life, remaining life, and tool status (including the remaining amount of the tool length value) of each tool. Wherein, the maximum service life, the group cutter and the cutter length value of each cutter are required to be set.

In the present embodiment, three cutters are taken as an example, which are a first cutter (T1), a second cutter (T2), and a third cutter (T3), wherein the maximum lifetime of each cutter is set to be 3 times, and the first cutter and the third cutter are set to be the same group cutter (group 1 in the figure), and the second cutter is another group cutter (group 2 in the figure).

Then, the mode is switched to the automatic mode, and then the machining is started. Wherein, each cutter needs to click to start processing respectively.

And finally, observing a processing status page to obtain the relevant status of each cutter in time.

As shown in fig. 2, the machining status page includes the coordinates, state, machining time, and operation program of each tool, and when the life of a certain tool is reached, an alarm is popped up. The group knives can be automatically called and replaced after the service lives of the group knives are up, the corresponding knife length values are called, and only when the service lives of all the knives are up, an alarm prompt is popped up.

For example, in the present embodiment, after the first cutter is machined three times, the second cutter is also machined three times, and in the process of starting machining for the fourth time, since the second cutter reaches the early warning life and there is no other cutter in the group of cutters where the second cutter is located, the alarm prompt of "T2 cutter life is reached" is sent; at the moment, because the group of the first cutter is provided with the third cutter, the third cutter can be automatically called and replaced to continue processing, and the cutter length corresponding to the third cutter at the moment is called, so that the processing can be continued without cutter setting again.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention.
