Calculation of the offset of the inclined hole in the coordinate boring machine
The workpiece shown in Figure 1 is generally machined on a coordinate boring machine. Figure 2 is a schematic diagram of the workpiece clamping. The workpiece is clamped on the mechanical universal turntable. After the two straight holes are smashed, the circular turret rotates 90°-α (as shown in the figure). When the angle shown is 1), the inclined hole is machined. At this time, the table should be moved by an offset so as to ensure the machining of the center distance between the straight hole and the inclined hole by 90±0.02 mm. How should this offset be calculated? The calculations are analyzed separately below.
