What causes the length of rivet to be too long during operation calculation?

In the actual riveting process, it is found that the length calculated according to the secondary formula is too long for two reasons:

1. Determined by CIMC’s riveting equipment. The manual riveting tool adopts hydraulic power, and the pressure riveting process is relatively slow (according to the foreign riveting process), in addition, the composite plate is relatively soft, so it is easy to produce skew;

2.According to the provisions of the mechanical design manual, for example, if the rivet diameter is 6.3, the drilling diameter should be 6.7. However, the company’s riveting equipment cannot complete such riveting, and the hole of 6.3 must be used.
