The quality of the individual parts are also inspected just after exiting the mold. Since thousands of parts are made daily, a complete inspection would be difficult. Consequently, line inspectors may randomly check the plastic parts at fixed time intervals and check to ensure they meet size, shape, and consistency specifications. This sampling method provides a good indication of the quality of the overall Rubik's cube production run. Things that are looked for include deformed parts, improperly fitted parts and inappropriate labeling. While visual inspection is the primary test method employed, more rigorous measurements may also be performed. Measuring equipment is used to check the length, width, and thickness of each part. Typically, devices such as a vernier caliper, a micrometer, or a microscope are used. Just prior to putting a cube in the packaging it may be twisted to ensure that it holds together and is in proper working order. This can be done by hand or by a turning machine. If a toy is found to be defective it is placed aside to be reworked later.
Puzzle makers have been creating problems for people to solve for centuries. Some of the earliest puzzles date back to the time of the ancient Greeks and Romans. The Chinese have a ring puzzle that is thought to have been developed during the second century A.D. This was first described by Italian mathematician Girolamo Carolano (Cardan) in 1550. When the printing press was invented, complete books of mathematical and mechanical problems designed specifically for recreation were circulated. Rubix Build
There are many approaches on how to solve the Rubik's Cube. All these methods have different levels of difficulties, for speedcubers or beginners, even for solving the cube blindfolded. People usually get stuck solving the cube after completing the first face, after that they need some help. In the following article I'm going to show you the easiest way to solve the cube using the beginner's method.
When you eventually get the desired position, there are two slightly different variations of it. For this, we need to look at the front of the cube. The yellow corner facing the front can be  in two positions: Either facing the front, or facing the right. In the first image, it is facing the front. This shows you have Sune. To solve it, just do the above algorithm one more time, and you should have oriented all of the top layer.

Repeat the process. Turn back to your blue side and repeat the turns on opposite sides. Then, return once more to the red side and turn the opposite sides in opposite directions. And last, return once more to the blue side and turn the opposite sides in opposite directions. When you finish, you should have a staircase-like zig-zag across four sides of your Rubik’s cube.[4] Rubiks Build It Solve It Review
The most important part in the manufacture of a Rubik's cube is designing the mold for the various pieces. A mold is a cavity carved into steel that has the inverse shape of the part that it will produce. When liquid plastic is put into the mold, it takes on the mold's shape when it cools. The creation of the mold is extremely precise. The cavity is highly polished to remove any flaws on the surface. Any flaw would be reproduced on each of the millions of pieces that the mold will produce. In the manufacture of the cube parts, a two piece mold is typically employed. During production, the two mold pieces are brought together to form the plastic part and then opened to release it. The tool includes ejector pins that release the molded parts from the tools as it opens. All the parts are molded with auto gating tools that automatically remove the parts from the sprue as it is ejected. The molds are also produced with a slight taper, called release angle, which aids in removal. Finally, when molds are designed, they are slightly bigger than the pieces that they ultimately will produce. This is because as the plastics cool, they shrink. Different plastics will have a different shrink rate, and each tool must be specifically designed for the material that will be used.

The centre pieces on each face, as you may have noticed from playing around with the cube, can't be moved to another spot, only rotated. So we can use this to our advantage by building around the centres. The best centre to build your first cross around is the white centre, as many guides and resources on the web start with a white face, so if you need to look up some steps and examples elsewhere, your cube will look similar to the one that is being used in other demonstrations.

An important thing to note is that this task is not a light one. It may require several hours of attempts. If you'd rather just solve the cube in your hand and forget about it rather than being able to solve any cube you're given, there are plenty of solvers available on the web. However, the satisfaction of holding a completed Rubik's Cube in your hand and thinking “I did that, and I can do it again” is greater than most, mainly due to the fact that the puzzle has been present in all our lives at some point. By the mid 1980's, an estimated fifth of the world's population had attempted to solve the cube. If you want to stand out and say that you can defeat the puzzle, time and determination is a large factor. Rubix Build
