The conventional braiding machine is a tool in the textile industry that is commonly used to produce prusik ropes. The term "braiding" refers to the process of intertwining multiple threads or yarns to form new patterns and shapes. Working principle of a conventional braiding machine is similar to braiding, where several carriers move following a specific pattern to create the desired product. Term "conventional" refers to the machine's design, which utilizes plastic carriers without spring tensioners. Production efficiency of conventional braiding machines heavily relies on the smooth movement of the carriers. Issues with carrier movement can lead to an ineffective and inefficient production process. This research aims to address this problem by analyzing the stack-up tolerances in the carrier movement system of a conventional braiding machine. The analysis begins by measuring every component of the existing braiding machine using manual measuring tools or a Coordinate Measuring Machine (CMM). The measurement results are then recreated as a model using SolidWorks software. This model is called the "real product model". Next, a "ideal model" is created based on standard components. This model is analyzed for the functionality of each feature of the components that affects carrier movement. The appropriate type of geometric tolerance is then determined for each feature. The model is then modified to eliminate the shortcomings of the previous model. The modified model is called the "new model". Next step is to determine the values for dimensional and geometric tolerances using a worst-case analysis approach. Outcomes of this research are a stack-up tolerance analysis and the technical drawing of carrier movement system in a conventional braiding machine.
