In this blog we will learn about the axes in context of CNC machining. We know from the study of geometry that an axis refers to a line which acts as a reference for defining the position of any point in space. Two axis can define the position of a point in a two dimensional plane while 3 axis are required to define the position of a point in the three dimensional context. This discussion is necessary this context of CNC machining because the cutting tool also has to be referred to a particular point in space in relation to the work piece.
Apart from the three dimensions which define the position of the working tool, the fourth dimension can also be defined in terms of CNC machining which is present due to the motion of the worktable along the vertical and horizontal planes.
Some of the machines also define a fifth dimension which is due to the flexibility of the spindle to rotate at an angle as compared to the work piece. Of course in the earlier days a manual operator did all these manipulations of moving the tool and the work piece in different dimensions but these days precise computer control can be used to do the same.
