Share an experience in which you've successfully learned how to handle a new piece of equipment? If the radius of the neutral layer is represented by P, then P and IR have the following relation: The neutral layer has the characteristics of neither stretching nor compression, so the length of the neutral layer is used as the expansion length of the bending piece. In addition, they really should check tooling tolerances each time a punch and die is pulled from storage. A press brake operator should know his tooling just as he knows his machine and applies the appropriate tools for the forming job in hand. Because the pressure is not as intense as it is when coining, the operator must account for spring back. The max bending force cannot exceed 20 tons. First, I would approach them in a professional manner and explain why it is important to follow safety protocols when using this type of machinery. 4) Slide the slider gently onto the two blocks (the lower face of the slider mold is in contact with the blocks). Example: Safety is always my top priority when working with a press brake. The workpiece must be positioned according to the movement of the rear stop finger so that the workpiece will not collide with the rear gear. If the machine is designed for off-centre loading, it can sometimes be better to form the part off-centre. When the rear stopper is positioned, it will push the plate and cause the plate to be extruded, so when bending, it is necessary to place the plate bending after the positioning of the rear stopper is completed. Example: If a press brake isnt working properly, I would first check the machines safety features to make sure they are all functioning correctly. Describe a time when you had to work under pressure and tight deadlines with a press brake.
