The latest laser cutting machine and practical function concept of light projection to the line

Laser pendulum cutter practical function and the concept of projection to the line object under the light, the shadow on the floor or wall, this shadow reflects the shape of the object) trapped in some respects temple), which is carrying a shadow phenomenon. According to this phenomenon, and puts forward the form object graphics side to write to, namely, projection method. Projection is a set of rays is obtained by back inch to reserve plane and graphic method since the rays from the point s is called the center of projection. Recommended reading: in 2015, cutter material shear rays called projection line, reserve plane called plane, the resulting graph is called the projection on the flat surface. The classification of the projection projection into centre projection and parallel projection CI) Center projection projection line of concurrent point projection method is called the center projection method according to the center of the projection method to get the projection is called the center of the projection. 。 Film, photography is the center of the projection, etc. Central projection of projection graphics do not reflect the real size of object, it is often used for map building. Rarely used in mechanical drawing. Price cutting machine cutting machine practical function and parallel to the line projection projection line parallel projection method called parallel projection method according to the parallel projection method of projection is called parallel projection. In the parallel projection, according to the projection line and plane Angle is different, can divide again for oblique projection and IE. Parallel projection and projection is called the oblique projection plane tilt. Parallel projection line and plane of vertical projection called shadow
