Circumference is a mathematical term, which refers to the trajectory of a moving point moving once (that is, 360 degrees) on a plane with a certain distance as the center.

Definition of words:

Mathematical terms. When a moving point moves a certain distance r from a fixed point, the largest space that the moving point may pass through is a circle. The angle of the vertex on the center of the circle is called the central angle. The angle at which the vertex is on the circumference and both sides intersect with the circle is called the circumferential angle. Forming the boundary line of a circular plane.

Main concepts:

The golden section circle is a graphic analysis method which mainly analyzes the golden section ratio of the circle. Choose significant high and low points or time points where key positions are located, and make a series of circles to represent resistance and support backwards. In physics, a circle refers to the motion of a particle on a circle with R as the center, that is, its trajectory is a circle, which is called "circular motion".

Application:

Circumferential milling is a kind of milling technology to manufacture cylindrical surface through the circular feed motion of milling cutter. In recent years, due to the progress of machining center and tool manufacturing technology, the development and wide application of this milling technology have been promoted. Based on the principle of circumferential milling, it has been widely used in many different machining tasks, such as milling holes, milling inner (outer) grooves, milling threads, chamfering, milling annular end faces and milling counterbores.

Because of its advantages of high processing efficiency, wide application range, and being combined with other processing technologies, this kind of peripheral milling technology has been applied more and more in industrial production, especially in automobile industry. Realizing the circular feed motion of milling cutter is the premise of circular milling. In the NC machining center, the circular feed motion of milling cutter can be realized by circular interpolation of X axis and Y axis.

You can also realize the spiral feed motion of the milling cutter through the spiral interpolation of X-axis, Y-axis and Z-axis, and realize various circumferential milling through numerical control programs. High dynamic machining center driven by linear motor and equipped with precision numerical control system can not only reduce the basic time of ring milling, but also improve the machining accuracy of ring milling, so that ring milling can replace boring and drilling and milling threads can replace traditional tapping.
