CNC carving and milling machine tool spindle motion space analysis

CNC carving and milling machine tool spindle motion parameters, the Z to the height of main shaft and parameters of the attitude Angle is independent parameters, in the process of machining, limited to the structure size, need analysis and study on its working space. CNC carving and milling machine tool spindle working space mainly by each branch of guide rail length, the rotation of the pendulum Angle, of swinging Angle of ball joint and restrictions. CNC carving and milling machine tool spindle structure parameters of the parallel mechanism are: three branch of guide rail length is determined by the maximum value Lmax and shortest Lmin, ball joint, and rotation of the pendulum Angle Hmax maximum, minimum Hmin, spindle height range Zmin ~ Zmax moving platform work. In this paper, the working space generation method is: 1) Moving platform will be moved to the highly Z0 to certain step length. 2) According to the previous theory analysis, we can seek out the origin of coordinates, the length of the three drive branch, three ball joint and the rotation Angle, interference inspection whether length overrun or collision; Without the above situation, continued to perform 2) Until the interference occurs, (at this time B0 - 1) Is the moving platform in Z0 height can reach the maximum slope Angle Bmax. Interference occurs after exit 2) To return to 1) Increase in height to start, to find the different height corresponding dynamic is the origin of coordinates and can reach maximum obliquity Bmax, generate CNC engraving and milling machine > spindle working space of the moving platform of the bed.
