V-Blocks Potential Error and Uncertainty

V-Blocks

V Block

 

 

 

V Blocks are utilized in conjunction with Surface Plates while performing Layout Inspection, and as a holding fixture for CMM, Optical Comparator, and other devices

Typically many users are unaware of the uncertainties and unable to assess the validity of V-Blocks

 

Common issues are, using the wrong angle type, lack of considering potential impact, or thinking “it’s just a reference”

In many cases there may not be a significant issue, however in some cases where the uncertainty is considerable in relation to the product tolerance, there is impact to product and the results are impaired

 

Areas of concern are

V Angle accuracy and angular surface wear

Parallelism of V to Bottom Surface

Centrality of V to Side Faces

Perpendicularity of V to End faces

Any nicks or damage affecting positional accuracy

There are various types, 60 or 90 degree, with or without clamps, some clear the side surfaces with clamp in place, in various materials Steel, Granite, Magnetic,
