Procedure for simulating tablet compression

A procedure of a tablet compound being pressed into a tablet in a desired tablet press by using a trial tablet press which simulates the tablet compound being pressed into the tablet in the desired tablet press, so that the desired tablet press is controlled to conform to measured movements obtained from the trial tablet press, wherein in the desired tablet press, the tablet compound is placed in a pressing matrix of a desired tablet pressing device, the tablet compound is compressed by punch members, provided by a trial tablet pressing device, on opposite sides of the pressing matrix of the desired tablet pressing device, and wherein a motion path of each of the punch members is in accordance with a predetermined motion path, the procedure comprising the steps of:

• providing a displacement transducer for each of the punch members of the trial tablet pressing device, each displacement transducer being in conjunction with each of the punch members;
• installing the punch members on opposite sides of a pressing matrix of the trial tablet pressing device;
• placing the tablet compound in the pressing matrix of the trial tablet pressing device;
• pressing the tablet compound by the punch members;
• measuring a motion path of at least one of the punch members during pressing of the trial tablet press by at least one of the displacement transducers;
• transferring results of measurements obtained from at least one of the displacement transducers to a computer which controls an operation of the trial tablet press;
• forming a file in the computer;
• controlling the motion path of at least one of the punch members in the trial tablet press by the computer in accordance with the file formed;
• installing the punch members in the desired tablet pressing device on opposite sides of the pressing matrix of the desired tablet pressing device;
• placing the tablet compound in the pressing matrix of the desired tablet pressing device;
• pressing the tablet compound in the desired tablet press;
• measuring the motion path of at least one of said punch members during pressing of the desired tablet press by at least one of said displacement transducers;
• transferring results of measurements obtained from at least one of the displacement transducers to the computer which controls an operation of the desired tablet press;
• and
• controlling the motion path of at least one of the punch members in the desired tablet press by the computer by using the results of measurements obtained from the displacement transducers in the desired tablet press together with the results of measurements obtained from the trial tablet press.
