Became a Quality Vision International company in 2005.

QVI (OGP) is a 72 years old private company with HQ in Rochester, NY and is a leader in multi-sensor CMMs

• KOTEM has a long history of software products• Prior to 2005 KOTEM products where sold to OEMs

under their brand names.

• SmartFit 3D in 1992

• MeasureFit in 1998

• Recent KOTEM Products • SmartProfile 3D in 2008

• KOTEM EVOLVE started work in 2006 released in 2016

GD&T and Dimensional Evaluation Software for Manufacturing Quality Control and Analysis

EVOLVE SmartProfile

4

• Hardware independent, point data can

be used from any measurement system

• Offline and “mobile”, faster evaluation

• Drawing or PMI based measurement

callouts

• Broadest support of ASME and ISO standards

+ Explanations

• Automatic evaluation + reporting

• Quick visual Go/No-Go analysis

➢Eliminate results variability caused by different metrology software packages’ evaluation techniques

➢Eliminate human error caused by incorrect interpretation of standards and drawings

➢Visual results allow quick assessment of part functionality and determination of required process corrections

EVOLVE Data Preparation

This tool is for importing and processing scan or CT data

Dense and noisy scan data captured

quickly by a laser scanner

Reliable, sparse, ’CMM like’ point data for

standard based GD&T evaluatuion

12

EVOLVE Data Preparation

• Import points from any sensor type (.stl is supported)

• Standard based filters

• CAD model can be used to provide intelligence

• Eliminate points by CAD deviation (color map)

• Noise reduction, point elimination

• CMM-like sampler

• Source-Result / Before-After visu.

EVOLVE LNP Experience

13

1. Importing and processing measurements using the DataPrep functionality

2. Reduce the Large Number of Points, extract CMM-like high quality points

3. Evaluating the measurements based on the reduced points

4. Analyze the results graphically with color maps

5. Carry out a simple CAD-Scan deviation analysis (use BestFit alignement and

Least Squares evaluation technic if needed)

6. Document the results in reports

7. Automate and replay the process
