Portable Coordinate Measuring Machine (CMM) Use in the Foundry Improving Tolerances and Dimensional Control The McConway & Torley Group manufactures large steel castings for the railroad industry, using a combination of green sand, cold box and no bake resin binder systems. Use of a portable CMM has enabled measuring accuracy to 0.007” on castings which otherwise do not fit onto a traditional CMM. Data from the CMM can automatically enter into AutoCAD 14, allowing complete profiling of a casting and aiding reverse engineering.
