In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the relevant drawings.

Examples

A cutter selecting method based on a six-side drilling machining system is shown in figures 1 and 2 and comprises the following steps:

s1: acquiring a processing cutter list of a first primitive Pi;

s2: matching the first primitive Pi with cutters in a machining cutter list to obtain a first cutter Tnk;

s4: and if the distance between the first primitive Pi and the second primitive Pj along the X direction or the Y direction of the plate is consistent with the distance between the first cutter Tnk and the second cutter Tk along the X direction or the Y direction of the plate, performing combined cutter matching.

Further, the step of obtaining the processing tool list of the first primitive Pi includes:

traversing the primitive list to obtain a first primitive Pi;

traversing the cutter list to obtain a cutter Tm;

judging whether the processing radius of the first primitive Pi is equal to that of the cutter Tm or not;

if the primitive Pi is equal to the preset value, acquiring a processing cutter list NewT of the first primitive Pi;

and if not, traversing the tool list to obtain the next tool Tn.

The step of matching the second primitive Pj with another tool in the processing tool list to obtain the second tool Tk includes:

traversing the primitive list to obtain a second primitive Pj;

comparing whether the processing depth of the first primitive Pi and the second primitive Pj is consistent or not;

if the two cutter Tk are consistent, traversing the cutter list to obtain a second cutter Tk;

and if the pixel values are inconsistent, traversing the pixel list again to obtain a next second pixel Pj.

Traversing the primitive list by adopting a recursive algorithm, selecting a first primitive Pi without an assigned tool number, selecting all tool lists capable of processing the first primitive Pi according to the primitive processing radius and the processing depth, matching each tool in the tool lists by using the first primitive Pi in sequence, and comparing the tool lists with another second primitive Pj which repeats the operation and the selected tool.

If the distance between the first primitive Pi and the second primitive Pj along the X direction or the Y direction of the plate is consistent with the distance between the first cutter Tnk and the second cutter Tk along the X direction or the Y direction of the plate, the first primitive Pi and the second primitive Pj can be matched with a combined cutter, otherwise, the first primitive Pi and the second primitive Pj directly enter the next cutter selection cycle.

In the embodiment of the present invention, if the distance between the first primitive Pi and the second primitive Pj along the X direction or the Y direction of the plate material is consistent with the distance between the first tool Tnk and the second tool Tk along the X direction or the Y direction of the plate material, the specific evaluation rule expression of the step of performing the matching of the gang tool includes:

if the distance between the first primitive Pi and the second primitive Pj along the X direction or the Y direction of the plate material is consistent with the distance between the first cutter Tnk and the second cutter Tk along the X direction or the Y direction of the plate material, the step of matching the combined cutter further comprises:

and storing the primitive set after the knife selection when the number of the combined knives reaches the target number of the combined knives.

In the embodiment of the invention, as the number of the combined knives is limited by a mechanical structure, the target number of the combined knives, namely the maximum value of the number of the combined knives is 4. If the mechanical structure supports more knives for simultaneous machining, other numbers of combined knives can be obtained by modifying the parameters of the combined knives.

When the number of the combined knives reaches the target number of the combined knives, after the step of storing the primitive set after knife selection, the method further comprises the following steps:

and if the combination knife exists, selecting the primitive list with the large number of the combination knives.

When the number of the combined knives reaches the target number of the combined knives, after the step of storing the primitive set after knife selection, the method further comprises the following steps:

and if the combined knife does not exist, selecting a knife tool in the combined knife, and updating the primitive list.

If the combined knife does not exist, after the steps of selecting a knife in the combined knife and updating the primitive list, the method further comprises the following steps:

and selecting the cutter with small upper, lower, left and right offsets from the cutter according to the upper, lower, left and right directions of the primitive without the combined cutter.

The primitive list comprises a board front primitive set, a board side primitive set, a board back primitive set, a board front vertical hole set and a board side vertical hole set, the primitive list further comprises other board front primitive sets and other board back primitive sets, and the cutter list comprises an upper drill bag vertical hole machining cutter set, a lower drill bag vertical hole machining cutter set, an upper drill bag groove machining cutter set, a lower drill bag groove machining cutter set, a left side machining cutter set, a right side machining cutter set, an upper side machining cutter set and a lower side machining cutter set.

In the primitive list and tool list analysis, data needs to be sorted and transmitted. Based on the operational characteristics of the woodworking processing system, additional attention needs to be paid to the type and location of the graphical elements. Before the combination knife is matched, whether the primitive list has the combination condition needs to be judged. Because in actual processing, different tool numbers correspond to different positions and different types of graphical elements. For example, the No. 24 cutter and the No. 35 cutter belong to the milling cutter, but the No. 24 cutter can only process the groove on the front surface of the plate, and the No. 35 cutter can only process the groove on the back surface of the plate. Similarly, although the cutters 1 to 15, 25 to 34 and 16 to 23 can process vertical holes, each cutter can only process designated graphic elements because of the mechanical structure position of the cutter and the radius of the cutter. Therefore, the primitive and tool data analysis is subdivided into, according to primitive position and type: the processing tool set comprises a plate front primitive set, a plate side primitive set, a plate back primitive set, a plate front vertical hole set, a plate side vertical hole set, other plate front primitive sets, other plate back primitive sets, an upper drill bag vertical hole processing tool set, a lower drill bag vertical hole processing tool set, an upper drill bag groove processing tool set, a lower drill bag groove processing tool set, a left side processing tool set, a right side processing tool set, an upper side processing tool set and a lower side processing tool set.

The cutter selecting method based on the six-sided drilling processing system provided by the embodiment of the invention has the advantages that the times of cutter discharging and cutter retracting are minimum, if the combined cutter exists, the cutter list of the maximum combined cutter is selected, and the cutter numbers in the combined cutter list are preferentially matched for the primitives of other non-combined cutters according to the primitive radius and the processing depth; and if the condition of the combined cutter does not exist, selecting the cutter number with the minimum offset of the upper part, the lower part, the left part and the right part in the cutter according to the upper part, the lower part, the left part and the right part of the primitive directly. Through the optimization, the optimal cutter selection can be freely combined under the set condition, so that the six-sided drill can reasonably discharge the cutter to cut the wood board conveniently, and by using the cutter selection method, the continuity of the woodworking cutting motion can be realized under the limited conditions that the combined cutter number does not exceed a limited value, the cutter discharge and retraction times are minimum, the cutter discharge displacement offset is minimum and the like, and the cutting efficiency is further improved.
