Method for Measuring Tooth Thickness BPD in Broached Workpieces: ❶ Preparation Materials (Thailand - Samut Prakan)

The key to precision spline machining: Pursuing fitting accuracy with BPD measurement. Broaching is a processing method used to create precise internal shapes such as splines and gears. In general gear machining, BBD (Bitween Ball Diameter) measurement is the mainstream, but in the case of broached spline holes, BPD (Bitween Pin Diameter) measurement is the best way to check the fitting accuracy. This is because using a pin to measure the minimum tooth thickness allows for an accuracy evaluation that is closer to the actual fitting state. ■ Features BPD measurement is characterized by using a pin instead of a ball. The pin is grounded at the minimum tooth thickness position in the lead direction, allowing for more accurate tooth thickness measurement. This makes it possible to improve the fitting accuracy of broached spline holes and improve product reliability. ■ Specifications For BPD measurement, a parallel block with a reference dimension of 25 mm is used. It is important to select a parallel block that does not deviate parallelly no matter what position it is slid to. For the arrangement of the measuring tool, choose a block gauge size 1-2mm larger than the drawing specification and use it together with a measuring pin to obtain accurate measurements. For example, if the illustrated BPD is 35mm and the pin diameter is 1.5mm, the calculation formula is 35(BP)-25(parallel block)+2=12mm. In this way, BPD measurement is a method that dramatically improves the accuracy of broaching. By utilizing these measurement techniques, it is possible to provide high-quality products to the market in order to achieve accurate fitting.

Method for Measuring Tooth Thickness BPD in Broached Workpieces: ❷ Load Application (Thailand - Samut Prakan)

Practical procedure for BPD measurement to measure accuracy with a solid feel. The accuracy of spline holes in broaching is an important factor that determines the fitting performance. Instead of the conventional BBD (Bitween Ball Diameter) measurement, BPD measurement using a pin allows for a more accurate evaluation of the minimum tooth thickness in the work lead direction. This contributes greatly to quality assurance of the target workpiece for broaching. ■Features BPD measurement is an accuracy evaluation method for optimizing the fitting of spline holes after broaching. In this method, the pin is grounded at the minimum tooth thickness position, allowing for measurements that accurately reflect the actual fitting state. It can also detect minute errors that are often overlooked in conventional BBD measurements, achieving higher quality control. ■Specifications The process of loading is an important step in performing high-precision BPD measurements. By applying appropriate pressure to the parallel block, a stable state is created in which the pin gauge does not fall off. As shown in the photo, it is important to make sure that the pin does not fall off even if the block shakes while firmly holding the parallel block in your hand. Pressing harder improves repeatability and ensures measurement reliability. The loading process in BPD measurement is an essential step to improve the accuracy of quality control. This step allows us to further improve the accuracy of spline hole processing and provide reliable products. For more details, please download the PDF or feel free to contact us.
