Benefits of technology
This patented technology allows for creation of patterns on sheets that have varying degrees of roughness along their edges without requiring extra machinery. It also makes it easier and faster than traditional methods like printing them onto paper by controllably adjustring how fast they move through space while keeping smoothly moving across its edge. Overall, these technical benefits improve manufacturing processes and reduce costs compared to current techniques such as lithography.
Problems solved by technology
The technical problem addressed in this patented method relates to improves the production rate at reduced costs while maintaining quality control over pattern formation without requiring expensive tools like marksings machine that are used throughout the entire fabrication process.

Embodiment
[0038] Taking incremental forming to process sheet metal into an inverted table, and at the same time make a LOVE pattern on the surface of the inverted table as an example, the specific steps are as follows:
[0039] Step 1: use the picture editing software to convert the pattern LOVE into dots, and process the pattern into a dotted figure composed of different points, such as Figure 5 shown;
[0040] Step 2: Put the dotted pattern into the coordinate grid, and determine the coordinates and cycle length L of each area of the dotted pattern by the coordinate grid, such as Figure 6 As shown, the coordinates and period length L of each black area are directly read from the coordinate grid, for example: the coordinates of area A are (5,13), the period length is 3, and the coordinates of area B are (9,11) , the cycle length is 1;
[0041] Step 3: According to the coordinates and period length L of each area on the dotted pattern determined in the second step, process the two...

The invention discloses a method for manufacturing patterns on the surface of a metal sheet incremental forming workpiece. The method comprises the following steps: carrying out point treatment on a pattern to be processed, drawing a coordinate grid, determining the coordinates and the cycle lengths of all areas of the pattern after point treatment, calculating the feeding speeds of all areas of the pattern subjected to point treatment and the rotating speed of a main shaft, setting different rotating speeds of the main shaft and the feeding speeds in a pattern area and a non-pattern area and enabling the surface of the forming workpiece to form areas with different surface qualities, wherein the areas form various figures, patterns, characters and the like. Compared with the existing method for manufacturing the pattern by use of a marking machine, the method for manufacturing patterns on the surface of the metal sheet incremental forming workpiece has the advantages that equipment is not additionally arranged, the processing procedures are not added, any pattern can be manufactured on the formed surface, the method is simple and convenient, the production efficiency of the product is improved and the production cost is reduced.
