HSR requires specially increased power weight ratio must have an in-cab signalling traditional systems are incapable of

recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...
