Video: Micro Inspection at Matrix Tooling
Various inspection and measurement resources help a moldmaker produce tooling for tiny molded parts.
Gary Johansson, VP of quality for Matrix Tooling of Wood Dale, Illinois, describes the various inspection technologies Matrix uses to measure tiny part features. Matrix makes injection molds for small, precision plastic parts, and it proves out these molds by molding the tiny parts within its own facility. The inspection resources used include microscope viewing within the machine tool, 3D stereoscope examination and video measurement. Also, a cross-sectional scanner is used for destructive measurement of the molded parts.
Simple "roughness" measurements remain useful in the increasingly stringent world of surface finish specifications. Here's a look at why surface measurement is important and how to use sophisticated portable gages to perform inspections on the shop floor.
A laser scanning system helps this shop capture the free-form surfaces on a hand-sculpted original. The resulting digitized models are the basis for CAM applications such as programming a CNC machining center.
Just because dial indicators have been around since the early 1900s, don't expect them to fade away with the last century. This tool's long-term popularity is well earned.
