I can think of several ways to make this work. None of them are simple. It would be awesome for you to add an EMBOSS feature to the IdeaStation. Inventor has one...
I don't think that sketch text can be used as a splitting tool or this would be much MUCH easier.
Anyway...
Here is one way:
1. Go to patch environment
2. Extrude the text as a surface feature through the wall of the cyliner
3. Return to model and use SPLIT FACE - the surfaces of the text would be your splitting tools (make sure you select any interior groups like on the R)
4. Use PRESS-PULL to slide the newly created text faces in or out. Be warned: The text will retain it's surface curve ratio as you bring it in or out - meaning non-normal edges.
Here is another way:
1. EXTRUDE the text into a new body.
2. Hide the cylinder
3. Create a sketch on the surface of the text
4. Use PROJECT - INTERSECT on the text
5. Use SPLIT FACE using sketch.
6. Use PRESS-PULL to slide the faces back or forward - same warning on normal lines.
**this method needs a bunch of features to work right. It also creates a negative image on the back side - which can be combined back to one solid when completed and it will dissolve**
Here is another way:
1. Go to the patch environment
2. Use OFFSET to create a surface at the depth of you required engraving.
3. Return to model and EXTRUDE the text outside the cylinder
4. This step can be accomplished multiple ways - this creates the fewest browser entries - Create a SKETCH on one of the flat faces of the cylinder. Create a CIRCLE at the same diameter as your surface offset from earlier (you could project if you wanted). Then hide the main cylinder body. EXTRUDE the new sketch circle to clear away much of the text features.
5. Use the COMBINE tool to remove the text bodies from the main cylinder.
There are others...
