Thompson Aluminum Casting Company is proud to have been certified by the Nadcap Management Council in recognition of accreditation, as listed in eAuditNet.com on the Qualified Manufacturers List, for our NonDestructive Testing capabilities.

In addition, we are ANAB accredited in accordance with requirements of AS9104/1:2012-01 by Smithers Quality Assessments, an accredited Aerospace Registration management Program Certification Body, to the quality management system standards and requirements AS9100:2016.

Thompson employs certified Level 3 X-Ray technicians and utilizes modern X-ray equipment. This process allows us to penetrate and examine the casting for subsurface discontinuities and to check its soundness. Working with our customers, we develop a sampling plan that may require random or 100% x-ray testing of each casting.

Our quality control technicians use state-of-the-art computerized ZEISS- Numerex Coordinate Measuring Machines to perform a complete dimensional inspection of a casting. This measuring machine is capable of providing SPC analytic data.

Our certified technicians can perform tensile testing on a test bar from a foundry run using a modern computerized instrumentation system. The operator can display the load in pounds, kilo pounds, ounces, newtons, grams or kilograms and can show load vs. strain or stress vs. strain. This automated system provides a greater degree of control, accuracy and data acquisition at a faster speed than possible with manually controlled test machines.

This system allows a certified technician to perform spectrographic analysis on a test disk. In less than 30 seconds, a complete chemical analysis of up to 64 elements, alloys and traces can be made and the results are immediately displayed and printed for statistical evaluation and production control.

I was thinking this morning how nice it would be to be able to specify with your jog box or even form the machine directly set move distances while programming directly online.

Example: I program a lot of thinks that are almost 2 dimensional so it is hard to fixture so we simply just change parts run a quick manual alignment however sometimes it can be tedious to go take and find those manual points but still get it close.

So if you are programming without CAD and not offline and you want the machine to move what you know to be 10mm you can have an options to move in Z+ Z- X+ X- ect. that exact amount instead of feathering the stick to where you want it given the option to change desired distant in seconds. Usually we know where we want to go in each direction we just don't know how far but we know roughly and we know which direction we want. This can make manually take points slightly more uniform as well short of going back through your code and just adjusting your coordinates.

I am not sure if this is possible with current jog boxes or windows in pc-dmis but our machine has an older style j box with no screen or anything. So a window for quick input directions in pc-dmis and or on the jog box would be awesome.

Software highlights include new user interface elements for a cleaner, simpler look and feel, more than 100 customer-driven enhancements and new software tools. PC-DMIS software comes standard with Hexagon Metrology measurement systems and is also available for a wide range of other metrology devices available in the marketplace.

The new versions of PC-DMIS now utilise Microsoft 6.0 Common Controls to provide a more cohesive and intuitive user interface. The appearance of common controls in dialog boxes has been streamlined throughout the software.

Ken Woodbine, President of Hexagon Metrology Software Division, said: "PC-DMIS 2013 MR1 is a customer-driven release based on real-world feedback from our PC-DMIS user forum and our Technical Support teams.

"Our mid-term software development strategy focuses on user requests and honing our existing tools, while concurrently implementing new ideas. The result is an ideal balance of usability advancements and innovative features to improve the user experience and the overall operational efficiency of the software."

The Blade Analysis module includes the ability to create a Nominal file and a Report file directly from PC-DMIS. Utilising the Blade Scan toolkit, users can now perform a defined path scan. The new Auto Feature measurement strategy enables users to scan a plane by moving along a path defined by a set of points. The software also includes a new simple graphical user interface to calibrate LSPX1C, LSPX1H, and LSPX1SF probe changers.

PC-DMIS 2013 MR1 also delivers a one-click manual target area for optical coordinate measuring machines (CMMs). For use with the Hexagon Optiv multi-sensor CMM, PC-DMIS Vision software adds a CWS (Chromatic White Light Sensor) scanning capability to their FDC (Firmware Distributed Control) Interface, as well as continuous wrist mapping for the CMS sensor. In the PC-DMIS Vision module, the Auto Focus feature gained improvements in both speed performance and overall focus repeatability.

The QuickFeature functionality enables the user to create Auto Features from a single click on a CAD model without using any menu options or dialog boxes. If models contain point features, and PC-DMIS is in curve mode, the user can use QuickFeature to box select and create multiple point features at a time. When using QuickFeature, dialog boxes with feature lists (such as for constructions or dimensions) can remain open. When adding new features into the measurement routine, PC-DMIS automatically adds them into the feature list and selects them for the current operation. QuickFeature gesture works with vector, edge, angle, and corner point features, plane, circle, ellipse, cylinder, cone and sphere shapes, also line, round and square slots, notch, and polygon features.

With a simple click of the QuickAlign button, users can automatically create a manual and Direct Computer Control (DCC) alignment based on the features currently selected in a measurement routine. PC-DMIS uses an algorithm based on geometric dimensioning and tolerancing (GD&T) datum precedence principles found in ASME Y14.5.1M to create the most common alignment types. Alignments are automatically created directly in the Edit window in both summary and command modes.

5. Model-Based Engineering

Model-Based Engineering (MBE), otherwise knownas Product and Manufacturing Information (PMI) or Model-Based Definition (MBD) is simply digital tolerance annotations embedded in a CAD model. The idea is to remove both the paper and the interpretation from the manufacturing and quality processes. The types of information included are geometric dimensioning and tolerancing (GD&T), component level materials, assembly level bills of materials (BOMs), engineering configurations and design intent. Learn more about how PC-DMIS utilizes MBE in this blog post.

The Change Management capabilities of PC-DMIS allow the user to ensure that their inspection routine, created from a previously imported InspectionPlan or CAD model, is updated to the latest revision. Double-clicking a feature name from any list will expand the display of parameters for that feature. This allows the user to compare values before updating the part program.

Introducedin PC-DMIS 2014, this tool allows users to set up portions of the measurement routine for measurement, based on operator selection. The Mini Routines tool also enables you to measure a selected dimension or group of dimensions from a long part program. With Mini Routines, you can automatically remeasure out of tolerance features when completing part-setup operations.

The Measurement Strategy Editor makes it easy to modify the default settings (number of hits, depth, void detection, strategy types, and so on) for all Auto Feature types. PC-DMIS writes these changes to the registry whenever you modify and then save settings in the Measurement Strategy Editor. PC-DMIS queries the registry and uses those settings when you create an Auto Feature.

Section Cut, a newer technology from Clip planes, allows you to specify a cut plane that intersects with a CAD model. To see this dialog box select Insert > Scan > Section Cut. Along the intersection line, you can define a start and end point between which points are created. From these points, you can choose to create vector point features or a Linear Open scan. This process does not visually cut the CAD model in any way like the clipping plane functionality does; instead, it acts as a tool to help you create Auto Vector Points or a Linear Open scan along the intersection line of the cut plane and the CAD model.
