Lead-in Lead-out horizontal arc... pleeeease heeeelp!!!!!

Hello

 

Thank you for entering

 

I am struggling to make a lead-in and lead-out with horizontal arc, using the 2017 version

I am making a profile on a part with 4 negative corners rad of 6mm

 

I am machining the all profile with a 20mm cutter and I want to use a 10mm end mill to make the 6mm corners rad

I want to machine only that bit the 20mm cutter left, and do to so I would like to entry and exit the pass with corner rad to avoid marks on the finished profile

 

What is the difference between horizontal arc and horizontal arc left/right?

 

I do not know what values to put on:

Linear move?

Angle?

Radius?

 

Any suggestion according this matter will be very appreciative

 

Thank you very much in advance for your support

I only use horizontal arc left when climb milling using constant-z toolpath. If I am conventional milling then I use horizontal arc right.

 

I use 90 for angle and a radius of .05"

I always choose horizontal arc (without left or right). It takes the "correct" one when you are climb or conventional milling (at least that is what I noticed).
