Is it possible to use if statements in CAM expressions?

[FrodoLoggins]

I want to make a roughing template that applies to 5 ZrN end mills (.5", .375", .25", etc.). I'd like the feedrate to update based off which tool I select.

Perfect world, I'd like to base the feedrate off the stepover percentage but I don't think that's possible.

Hi -

Yes, you can have simple conditions in your expressions. Here's an example:

tool_type == 'drill' ? 4 * tool_diameter : 2 * tool_diameter

This means "if tool_type is 'drill' then use 4 times tool_diameter, otherwise use 2 times tool_diameter.

You can use parentheses and AND (&&) and OR (||) in your expression, and even nest them:

(x == 4 || x == 7) ? 16 : (x < 2 ? 7 : 13)
