1. INTRODUCTION

The tablet is the most common pharmaceutical dosage form due to its many advantages, such as the economy of manufacture, superior chemical stability, and patient compliance (see Pharmaceutical Dosage Forms 〈1151〉). It is generally produced using a die-compaction process, where a constant volume of powder is poured into a die and compressed using two punches until reaching a target thickness. At the industrial level, this process is performed using rotary presses. This type of press can be equipped with many punches and dies (typically dozens). The punches and dies are placed on a turret that rotates. During this circular movement, the punches are moved vertically relative to the corresponding die using cams and rollers. Rollers are particularly used for movements that involve high forces, such as during the precompression or compression steps.
