Understanding Grooving: The Art of Precision Machining
Grooves may come out wider or narrower than planned. For example, a groove planned to be 2 mm could end up being 2.3 mm due to tool deflection or machine inaccuracies. This issue can be addressed by carefully calibrating the machine and selecting rigid and robust tools. In some cases, reducing the feed rate or depth of cut …
