How to make arcs when the four corners of the billboard are too sharp?
How to make billboards
Each billboard has its own unique production method. Let me tell you about the acrylic fonts: Acrylic fonts are divided according to their shapes. There are three standard names: 1: A: Flat drum character B: pointed drum character C: round drum character
Other shapes basically evolved from these three. For example, a pointed drum can evolve into a diamond shape, and a round drum can evolve into an arc shape. However, the shape of the characters will be completely different depending on the choice of tool and the depth of the cutter. A: The production and requirements of flat drum characters: Use copy paper to trace the desired characters on the density board, leaving 5cm on each side. Use a manual engraving machine to install the corresponding straight knife, and cut out the mold along the outer line of the characters (inside the line, others take the outside line). After the mold is cut out, use a file to smooth the mold. Then use a file and sandpaper to grind the sides and corners of the male and female molds of the characters into arc shapes. They must be smooth and even, and finally smooth them with sandpaper. You can also use a computer engraving machine to engrave the mold, add enough height and then smooth the edges and corners. B: The production and requirements of the pointed drum characters: The first step: The production method of the flat drum characters is the same, except that the sides and corners are not ground into arc shapes for the time being. Step 2: Heightening and shaping. According to the size of the characters and the width of the strokes (based on the widest stroke, draw a middle line starting from the second layer to see if the inclination on both sides is a 90-degree right angle, use this angle to position the thickness of the increase, and then macro section Choose an appropriate 45-degree bevel knife and install it on the multi-functional milling machine. Cut out the sharp drum with the face facing down. Use 502 glue or three-second glue to drip glue on each part of the sharp point to make it harder and not too hard. The mold is damaged during pre ssing, and there are no sharp parts. The height should be increased, and the repairs should be done properly. Extra large characters cannot be bought and can only be made by hand. C: The production and requirements of the round drum mask. : The first step is the same as the production method of flat drum characters, except that the sides and corners are not polished into arcs for the time being. The second step is to increase the height and shape. The thickness should be proportional to the size of the characters. Things that are made in a coordinated manner are beautiful. The steps are roughly the same as those for making sharp drum characters, except that the cutter is a fillet knife. 5. Requirements for making the bottom plate of the acrylic light box 1. The four sides of the positive mold of the bottom plate must be processed. The four corners should be smooth and rounded (that is, the four corners should be narrow at the top and wide at the bottom) to facilitate demoulding. 2. Grind the bottom of the female mold of the base plate with sandpaper. The angle should not be too large. It can reduce the gap between two base plates when they are spliced
