In this case the relative datum is always the last pro grammed position Such coordinates are referred to as incre mental coordinates increment increase They are also called incremental or chain dimensions since the positions are defined as a chain of dimensions Incremental coordinates are designated with the prefix I Example Incremental coordinates of position referenced to position Absolute coordinates of position X 10mm Y 5 mm Z 20 mm Incremental coordinates of position IX 10 mm Fig 1 7 Position definition through incremen IY 10 mm tal coordinates IZ 15 mm If you are drilling or milling a workpiece according to a drawing with incremental coordinates you are moving the tool by the value of the coordinates TNC 124 13 1 Fundamentals of Positioning Machine axis movements and position feedback Programming tool movements During workpiece machining an axis position is changed either by moving the tool or by moving the machine table on which the work piece is fixed When entering tool movements in a part program you always program as if the tool is moving and the work piece is stationary Position feedback The position feedback encoders linear encoders for linear axes angle encoders for rotary axes convert the movement of the machine axes into electrical signals The control evaluates these signals and constantly calculates the actual position of the machine ax
