      <p class="para_topic">The In-Process Workpiece (IPW) is a geometric shape that is produced by the Manufacturing system to represent the machined workpiece at each stage of machining.  According to the order of the operations in the <b class="uiTerm">Program Order View</b>, each operation tool path progressively reduces the IPW to mimic the material removed from the actual workpiece on the machine tool.  This provides exceptional benefits to the user and to the tool path processors.  For tool path generation, some of the operations can use the IPW shape from the previous operation as input, which reduces user interaction and improves tool path cutting efficiency.  For verification and simulation, the IPW is progressively modified by all tool paths throughout turning, milling, and drilling operations (with very few exceptions).
