Production molds and dies used in various forming processes are generally obtained from machining their complex 3D shapes from a CAD model and then making adjustments through a series of iterations involving local reworking. As a result, their shape differs slightly from the original CAD model. Depending on the tool size and complexity, reverse engineering their final shape and documenting it with a new CAD model can be a daunting task. Luckily, PolyWorks|Modeler™ offers functionalities to transfer the scanned surface of an object into a CAD/CAM software.
In this 15-minute webinar, our technical expert will demonstrate how to use surface modeling tools to reverse engineer a reworked area on a die using a network of NURBS surfaces, then blend those fitted surfaces into an existing CAD model for local CAD reconstruction purposes. Learn how you can save time documenting modifications done to tooling by integrating local changes into the original CAD model.
