Abstract

For mass production of speakers we have to prepare the component part to part and install the part accordance with their own functions, Quality Control (QC) makes sure the product is good or broken, Quality Control (QC) mechanism action based on the measurement tools and human resources (operator), to ensure the measuring instrument functions properly then each new measurement tools need to be checked periodically to ensure the measuring instrument in good condition.During the measurement process, Quality Control (QC) is inhibited by measuring parts that mushy or have shape changing big because of pressure is on conepaper part, if it occurred, it will cause charge and a loss of time. To compensate for the costs and loss of time, Quality Control (QC) create tools JIG ID (Inside Diameter) made of stainless steel 304 round bar with size Ø60x182mm this stainless steel for fairly fit because the stainless steel material resistant to heat, abrasion resistant and rustproof being choosed because JIG ID (Inside Diameter) will receive repetitive friction and resistant to low and high temperatures during the measurement process and saving.The idea of making JIG ID (Inside Diameter) is being affected by the human factor because measurements made by operator with other is not the same because of experience factor and pressure, then the idea that was created to deal with stress factors that showed using gravity (workpiece dropped down), so that the same measurement results obtained on each operator. And the results obtained on the two measurements can be seen that the most perfectly using JIG ID (Inside Diameter) with valuen 60.50mm.
