you stand the chance of leaving 'spurs' in your pattern with even a slightly-worn bit

That's the thing Lloyd Troch mops are roughers and need to be followed up with a finisher

If your have your step over aggressive enough there will be scalloping on the walls of the

pocket (this is a good sign you are in the ballpark).

I like the troc mops, they have their superpowers,but they are not a universal panacea for

all pocketing situations, some simple pockets for example a square with rounded corners

where the radii of the corners are somewhat larger than the diameter of the tool then a simple

pocket mop would be a better choice, however if the pocket has even just a little more complex geometry

then the troch mops offer a significant speed up in cut time.

Used with a dedicated roughing cutter and one of the feedrate adjusters which rip out the

positioning moves and replaces them with rapids and vary the feedrate to keep the chipload

constant make for fast pocketing between 40 -60 % faster than a standard pocket.

I had a look at the production files and roughly a third of them are troch mops the rest are

plain pockets where the pocket has simple geometry like rounded squares and rectangles with

radii larger than the tool radius.
