End-Scan Using a Ball Probe

How to perform end-scans with a ball probe. Back to VTube-LASER See End-Scan Technique Research

Why the End-Scan technique is important

This end-scan method is useful for situations where the only option is a ball probe - or where the Laser cannot reach effectively - but a ball probe can. Using a ball probe is very precise as long as the tube is properly held with a work holder. The main drawback is that the tube must be securely mounted without deforming the shape. It must also be touched - thereby potentially moving the tube - which will invalidate most measurements.)

Measure Setup

Set System Options, Measure 2 Tab, "Maximum Number of LLP Points in String" to 3 Set Measure Setup - LASER Tab: The LASER defaults to ON for CYLINDERS and END-SCANS. Set Measure Setup - LASER Tab: Cylinder stripes = 3 to 5 Set Measure Setup - LASER Tab: End-scan stripes = 5 Set Measure Setup - LASER Tab: Split bend stripes = 5 Set Measure Setup = Scan Rates Tab: Set all rates to TIMER for all scan types. Set Measure Setup = Scan Rates Tab: Set the Scan Rates TIMER is set to 0 for all TIMERS.

How To Use This End-Scan Technique

Align the scanner with a slight scissor angle across the end as is shown in the image on the right Attempt to hold the laser motionless when collecting the stripes across the end to increase repeatability. Consistently place the line across the same area of the tube end from measure to measure. Press the green button until VTube-LASER is finished scanning all the end stripes.
