Abstract
Making a piston includes receiving a piston crown including a combustion face forming a combustion bowl. The piston includes a base material, and a thermal barrier coating (TBC) material forming at least a portion of the combustion face including a bowl edge. Making a piston further includes advancing a polishing tool into contact with the combustion face, spinning the polishing tool such that a positive piston profile is polished via contact with a negative tool profile, and removing some of the TBC material based on the spinning the polishing tool relative to the piston.
