Functional and Operational Requirements to Be Fulfilled by Conical Picks Regarding Their Wear Rate and Investment Costs

User’s choices of conical picks currently involve specifying their material and geometric parameters (functional requirements), incorporating the place conditions work (operational requirements). The selection is usually made based on solely one criterion, which price. Thus, at stage both purchase operation, quality picks, as well matching for a specific machine, are not assessed. problem defining whether producer has fulfilled user’s requirements arises only when user questions picks’ quality. Analysis this resulted in developing assumptions, concepts research procedures cutting process requirements. procedure allows conducting tests to determine pick, type pick body WC-Co insert, wear rate (intensity). C2 index describes (intensity)—the smaller its value, slower pick’s wear. Laboratory were carried out AGH University Science Technology Kraków, Poland.
