Furthermore, the reserved space is 2 centimeters, the woodworking engraving machine is a three-axis engraving machine, only one surface of the plate can be machined by single machining of the three-axis engraving machine, and numerical control programming software of the woodworking engraving machine is JDpaint 5.19.

Further, the method comprises the following steps:

as shown in fig. 2, before machining, the tool is firmly mounted on the fixture, and the tool is zeroed for the CNC engraving machine, so that the zero point of the machine is aligned with the upper surface of the machining material at the starting point. After the processing begins, should carry out the processing of first notch, second notch, third notch and locating hole on the door plant earlier, carry out the operation of cutting off on first section and second section again, otherwise can lead to the milling flutes, the in-process of punching, processing raw materials lacks fixedly all around, and the plate is scrapped extremely easily, treats processing and accomplishes the back, takes off the shoe cabinet door plant that processes, and remaining strake is the clout, can be used as the processing of other little work pieces.

Furthermore, the processing raw material is a finger-jointed board with standard size of 1220 × 2440mm, the thickness of the finger-jointed board is 18mm, the used cutter is a round-bottom milling cutter with the diameter of 6mm, the size of the shoe cabinet door board is 700 × 390 × 18mm, each whole board of processing raw material can be used for processing 9 shoe cabinet door boards, the shoe cabinet door board surface is provided with a first linear notch, a second linear notch and a third linear notch which are milled, the linear notch sealed in the middle is milled by two groove milling procedures with different cutting depths, and the positioning hole is positioned on the cabinet door and used for positioning when a handle is installed.

Further, the method comprises the following steps:

as shown in FIG. 8, using the "decide as the starting point" command in the node editing process interface, the starting points of the segments are set according to the shortest path feed diagram, the starting point of the first segment is as close as possible to the set workpiece origin, the starting point of each following segment is as close as possible to the end point of the previous segment, the starting point of the segment ② corresponding to the milling cutter path in the shortest path feed diagram is above the line and close to the end point of the segment ① corresponding to the cutting cutter path, the finally set starting point is that the starting point of the segment ①③⑤⑦⑨ is at the lower end of the line, the starting point of the segment ②④⑥⑧ is at the upper end of the line, the starting point of the segment ⑩ is at the right end, and the ending point of the segment ⑨ is close to the end pointIs at the left end, near the end of line segment ⑩;

Assigning milling groove path parameters to the selected line segment ②④⑥⑧;

selecting a path group endowed with good parameters, selecting a 'separated tool path' in a tool path menu bar, then selecting 'separated into a single path', and converting the tool path group into a single isolated path;

finally, selecting a cutter path completely, clicking a cutter path sequencing command in a cutter path menu bar, wherein the sequence number at the starting point of each path is the sequence of processing, clicking a specified path sequence number, and sequencing the paths in sequence according to the sequence of the paths in the feeding schematic diagram of the shortest path;

and after the error is detected, clicking 'output tool path', selecting the original point of the workpiece, setting relevant parameters to output the path, converting the format of the path, and guiding the path into a numerical control engraving machine to process.

According to the principle of firstly walking inside and then walking outside, the plate needs to be stably fixed on the three-shaft woodworking engraving machine tool all the time in the working process. If the outer side of a workpiece is machined and the inner side is machined, the workpiece may be damaged due to unstable fixation of the periphery when the inner side of the workpiece is machined. Therefore, the principle of "go inside first and then outside" is followed during processing.

As shown in fig. 2, the surface of the door panel has grooves and holes to be processed, so during the design process of the knife path, one important point to be noticed is: the feed of the slot and the hole is carried out first, and then the feed of the cutting is carried out. This is because if the cutting command is executed first, the entire door panel is cut, and there are various problems that may occur when the door panel is not fixed and the groove and hole are processed, and even the panel is scrapped. For example, the schematic feed shown in fig. 8, the longitudinal cutting and the groove milling operation are performed first, and the transverse cutting operation is performed last, which is reasonable, and follows the principle of "go inside first and go outside later".

Some distances are reserved around the plate during processing, rough edge processing is performed, the boundary surface roughness of the artificial plate is usually high, the operation of subsequent edge sealing and other processes can be influenced if the artificial plate is not processed, and the quality of a workpiece is reduced. The engraving machine integration process can also carry out the operation of processing rough edges. Because the surface roughness processed by the milling cutter is lower, the milling cutter on the woodworking engraving machine can be used for milling the periphery of the workpiece, and the surface roughness is reduced while cutting materials. Some distance is reserved around the plate, and the part is milled off during processing, so that the processing procedure of rough edges can be finished.

As the wood frames around the workpieces in fig. 2 and 5 are the rest of raw materials subjected to the 'rough selvedge processing', the wood frames can be used for manufacturing other small workpieces due to the same cross-sectional dimension: for example, some parts of the furniture have insufficient supporting force, and a filler strip or a gasket can be added for reinforcement.

Before programming, the drawn graphs are cut into the form of single line segments or single curves, so that the logic is clear to sort, and if the single line segments are combined into a set, the set programmed tool path is an inseparable path group, which can cause the disorder of the feed sequence, such as ①⑨ in fig. 8

⑩ four line segments form a rectangle, if it is combined into a whole to program, the four sides of the rectangle will be arranged together to process in the feed, it can not be divided, it can be seen that after several sides are combined into a whole, the feed time can not be shorter than that of the single line programming, no matter how the optimization programming, when other parameters are the same, therefore, the drawn graph should be cut into the form of single line segment or single curve before programming for the purpose of logic clear, reasonable and scientific tool path sequencing.

The invention has the following beneficial effects:

1. according to the production method of the integrated plate-type furniture, a plurality of production processes such as cutting, punching, grooving, tenoning, surface curve modeling and burr processing are simplified into an integrated operation, and compared with the prior art, the automation degree of a numerical control woodworking engraving machine is high, and the processing speed is high.

2. According to the production method of the one-machine integrated plate type furniture, the graphs are cut into single line segments or single curves, the moving space is reserved around the plate, the moving path of the cutter is optimized according to the principle that the cutter moves inwards first and then outwards, the stroke distance of the cutter and the idle time of the cutter shaft can be reduced, the processing speed of the engraving machine is accelerated, and the energy consumption of a workshop is reduced.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
