For companies concerned with measurement deviation, this capability can be automated into the part program. With a fourth-axis vision machine, the part can be rotated to determine if the diameter changes. When it comes to measuring round parts with varying diameters such as fasteners and screws, the benefit of having the CAD model, and in particular, being able to inspect direct to the CAD model, allows for measuring the parts in sections.
It uses embedded geometric dimensioning and tolerancing (GD&T) to keep the entire file electronic, thereby saving revisions to blueprints and time spent communicating those changes. Change Manager is a function that updates changes to the CAD file in the inspection routine. Clearance Cube assigns a protective virtual envelope around the part and guides the probe to avoid that area, decreasing the possibility of crashes. The Path Optimizer calculates the most efficient moves of the CMM to speed inspections. New features automate the inspection process further to save time. Regardless of whether scanning technology is used or not, operators benefit from customized reporting, where only relevant features are pulled into the reports. Point clouds highlight out-of-tolerance features with a color-coded system that makes analysis-at-a-glance possible. Those using laser scanners also have the option of creating a point cloud from the exported measurement data. In some instances, customers have reported a 75-percent decrease in inspection times by implementing scanning in their routines. Scanned data, either via analog or laser generated, is gathered much more quickly than point-by-point probing. Users have the choice of equipping their coordinate measuring machines (CMMs) and portable CMMs from a selection of software modules for stationary CMMs (including PC-DMIS CAD and CAD++), PC-DMIS Portable, PC-DMIS Vision and PC-DMIS NC (for inspections on CNC machines).Īnother capability of this standard is its capacity to process scanned data. PC-DMIS can be installed on a range of metrology hardware from both Hexagon Metrology and other vendors. Facilitating a Common PlatformĪn underlying philosophy behind this communication standard is ensuring ease-of-use for operators. As the market embraced this new-found focus, the developers turned their attention to other benefits the software offered. It was originally based on DOS and was developed on the premise that CAD, well on its way to becoming the de facto standard in manufacturing, should be leveraged to interface with metrology hardware. PC-DMIS was developed in 1991 when William Wilcox and Mark Cluff decided to start a metrology software company. VIDEO: Emerging Leaders’ Viewpoints on Training and Retention
