A sponge cutting machine's cutting method and process

　　Background Technology:

　　Traditional cutting methods, especially when slicing wider sponges, often encounter issues with strip-shaped blades. During the twisting motion, controlling the rotation at both ends of the blade becomes challenging. As the ends are twisted into place, the central section, under the sponge's reactive force, tends to experience rotational lag and distortion—causing the middle part of the blade to fail to turn fully. This results in rounded protrusions or grooves forming at the angled edges of the finished sponge product, ultimately compromising the cutting quality.

　　Technical implementation details:

　　To address the above-mentioned issue, the present invention proposes a cutting method for a sponge cutting machine that features a reasonable design and a simple structure. It effectively resolves the problem of insufficient turning at the middle section of the tool before it is tightened, thereby improving the cutting quality.

　　A sponge cutting machine cutting method, comprising the following steps:

　　(1) On the CNC computer of the sponge cutting machine, launch the control software, enter the parameters and the dimensions of the sponge to be cut, and select the desired cutting path shape. The control software will then automatically calculate the tool’s cutting path.

　　(2) Place the sponge to be cut onto the conveyor belt and adjust its position properly.

　　(3) The tool cuts along the cutting path. Before the tool starts rotating, it pauses briefly, then first rotates to the initial cutting angle, followed by an additional rotation beyond that angle, and finally returns to the starting cutting angle while pausing again. Only after this delay does it begin cutting the next segment.

　　(4) Repeatedly twist and cut the tool until the desired shape is formed;

　　(5) Debur after forming.

　　In step (1), the tool's rotation is controlled by the control software.

　　The torsional strength midpoint of the tool is either at the cutting edge or 0.5 mm behind the cutting edge.

　　In step (3), the angle size is adjusted according to the hardness of the cutting sponge material: set a larger angle for harder materials, and a smaller angle for softer materials.

　　The advantage of the present invention is its rational design and simple structure, which allows for a delayed wait while the tool is being twisted. This ensures that the middle section of the tool cuts precisely into position before the tool is finally twisted to the initial cutting angle, then slightly rotated beyond that angle, and finally returned to the starting cutting angle—while maintaining a delay to allow the middle part of the tool to fully align. As a result, this innovative approach effectively addresses the issue of insufficient turning in the tool's middle section prior to twisting, significantly enhancing the overall cutting quality.
