Constant Radius Arm

This feature allows the system and/or the operator to change the line of sight angle while keeping the focal point of the scanner in the same location relative to the component being scanned. Our studies have shown us that this is a crucial aspect to any 3D scanning system.

Shot Sequence Programming Options

There are four Shot Sequence Programming options available to the operator.

  • Teach Pendent
  • Canned Cycle
  • Conversational
  • Offline Programming

Teach Pendent

This is the same as you would find on any robotic teach pendent system; position the scanner, take the shot and see if the shot stitches correctly to your previous shots and if this position is desired then ‘teach’ the position and move to the next.

Canned Cycle

Again, this is the same as any CNC machine, these are pre-programmed shot sequences for particular features that can be mixed and matched to develop an overall shot sequence for any given part. If additional scan coverage is required then use the teach pendent to add shots as desired.

Conversational Programming

This function allows the operator to tell the system the component dimensions, the relative complexity of the part geometry, and the portions of the part needing to be scanned. From this data the system will generate a shot sequence for you. If additional scan coverage is required then use the teach pendent to add shot as desired.

Offline Programming

This uses third party CAD software like SolidWorks to generate a shot sequence. This software will allow the operator to visualize the scan coverage of the component independent of the ComScan® system. Once the scanning project is setup on the system, then additional shots can be programmed if required. A shot sequence editor is provided in a spreadsheet format. This allows for shot sequence files to be edited on the fly or offline.

Modular Design

The ComScan® design is made up of a number of standard “off the shelf” sub-assemblies. Manual and powered 1000 mm, 750 mm, 500 mm radius arm sub-assemblies. 5 Axis tables, standard Rotary, and Trunnion sub-assemblies and standard laboratory and shop floor chassis sub-assemblies can be mixed and matched to build a ComScan® system specifically for any application.

Scanner Compatibility

The ComScan® software and hardware is completely independent for any scanner manufacturer. This allows the ComScan® system to support practically any scanner on the market today or in the future. What that does for our customers; is that we can retrofit your current scanner and in the future, if you decide to upgrade the scanner, ComScan® can support that upgrade even if you decide to change scanner manufactures. This makes the ComScan® a very safe and practical investment for our customers.

Virtual Object Space

CMM’s and CNC machines require physical object spaces. This requires the operator to tell the machine where the parts are in the machine’s work envelope. This establishes a mathematical relationship between the component and the machine. Any deviation to that relationship will result in inconstant data results. This is why CMM’s are in temperature controlled rooms and have a massive slab of granite to compensate for thermal deviation. This is why CMM’s need air bearings to compensate for friction and glass scales with closed-loop feedback controls to compensate for motion control errors like ball screw backlash. An area scanner mounted on a tripod, scanning a component setting on a table has NO physical or mathematical relationship. This is what makes area scanners such a forgiving data collection devices. The object space for these devices is ‘virtual’ since the data registration is done strictly on the computer.

The machine design concepts for the ComScan® systems maintain this non-mathematical relationship and are what allows us to use aluminum extrusions for chase frames and linear rails plus ball screws without motion control competition. The virtual object space combined with the repeatable shot sequence is what allows ComScan® to maintaining repeatability and reproducibly results, measured in tenths of an inch or microns.

This is what we call the… “Magic of ComScan®”
