...you have?
What speed? What forces?
Are you just moving the thing, or do you need to accurately position it? If so, to what precision?
Does it ***absolutely have to be*** a rack and pinion?
Does the motor ***absolutely have to be*** on the moving part?
Is your gearmotor 100% selected...
I hope you mean "linear speed profile", not linearly increasing acceleration.
But that requires constant acceleration, which you probably don't want to do.
Basically, you want the left half of this (from: https://www.digikey.jp/en/blog/motion-control-profiles-good-better-and-best)
Everything you need is here: https://phys.libretexts.org/Bookshelves/University_Physics/University_Physics_(OpenStax)/Book%3A_University_Physics_I_-_Mechanics_Sound_Oscillations_and_Waves_(OpenStax)/10%3A_Fixed-Axis_Rotation__Introduction/10.09%3A_Work_and_Power_for_Rotational_Motion
Huh? That's not relevant.
Anyways, how much clamping force do you need?
How to select fasteners:
Define the clamping force.
Decide the number of fasteners.
Decide material.
Decide diameter.
Decide if torque control is good enough.
If yes, calculate torque.
Make the workers financially responsible for their issued tools. Then they will find their own good method of marking.
Paint won't wear off that quickly, and won't wear off complete, and is cheap and easy to renew.
