What should the machine table be to bore a hole perpendicular to the face of the workpiece?

To bore a hole perpendicular to the face of the workpiece, the machine table should be set perpendicular to the spindle. This alignment is critical because when the spindle is vertical, having the table perpendicular ensures that the cutting tool will move straight down into the workpiece, creating a hole that is at a right angle to the surface of the part being machined.

In milling and drilling operations, achieving the correct orientation of the workpiece and the tool is fundamental to precision machining. If the table were parallel to the spindle, the hole would not be perpendicular to the face of the workpiece, potentially leading to inaccurate dimensions or misalignment of parts in subsequent assembly processes. Setting the table at an angle to the spindle would produce a hole that is neither vertical nor horizontal in relation to the workpiece face, further complicating the part's accuracy. Thus, ensuring the proper setup of the machine is essential for achieving the desired results.
