CONSTITUTION: A machine for forming a circumferential groove of a core hole comprises an electric motor(10), an elevation body(20), a support rack(30), a movable plate(40), and a fixed plate(50). The electric motor comprises a tool(12) for processing a circumferential groove of a core...
Method and apparatus for mirror-polishing of workpiece edges Two cylindrical polishing drums 2 and 2, each having a polishing work surface 2a on their outer circumference, are disposed at an interval smaller than the diameter of a workpiece 7. The polishing drums 2 and 2 are rotated at a re...

When I was debugging, I felt like the picking stops working if the picked position is out of the circumference of some radius calculated from the center of the graph, like this: Here is a video of it, I don't get the math yet, do you think something like this might be possible @pi...
the: bed as a whole. This may be explained by reference to Figure 4, wherein the 2 2,314 circle is representative of a roller. The bottom tangent line of length B may be considered a unit distance which happens to be here shown but does not have to be equal to the roller radius....
The drum, or belt, is made out of photoconductive material. Here are the actual steps involved in making a photocopy: The surface of the drum is charged. An intense beam of light moves across the paper that you have placed on the copier's glass surface. Light is reflected from white are...
since the second circle's circumference is half that of the first circle, it has to complete two full rotations to cover the same distance. This explains why the two gears, one with half the circumference of the other, have a gear ratio of 2:1. The smaller gear has to spin twice to...
