In the automatic control mode, the engraving and milling machine movement through the prior preparation of the processing program to produce action. So in the automatic mode, the system must be loaded with the processing program. In the incremental mode, the user is also through manual manipulation of the equipment, such as computer keyboard, hand-held box, manual pulse generator to control the machine. And engraving and milling machine point moving control is different is that the user a button action, that is, from the press to release, the motion of the machine only to determine the interval.
Engraving and milling machine in the inching mode, users through manual control equipment, such as computer keyboard, hand-held box, manual pulse generator to control the machine. When a user sends out signals through the devices, such as press the manual button, the machine continues until the signal disappears, such as when the user releases the manual button.
That is to say, the user can accurately control the displacement of the machine tool MDI mode is a kind of manual control mode. In this mode, the user can directly control the machine through the input G. System in some cases performed some default process control (such as the return to the origin of the workpiece), will automatically switched to the state MDI mode, but this will not affect the engraving and milling machine the user use.
How can make the engraving and milling machine to do the contradictory requirements of practice, draw the following conclusions, only for the production test:
(1) super wide columns and beams, we know that the Longmen style structure because of its excellent symmetry and excellent steel properties by the high speed cutting equipment manufacturers have been the preferred structure.
(2) engraving and milling machine tool body using high and low reinforcement with the mesh structure, and some directly using the honeycomb of the six angle network structure.
(3) for the mobile sector is unlike CNC milling is widened a lot of the interval between the guide rail and the guide rail, in order to overcome the adverse Xian carved machine torque.
(4) the rigidity of the machine tool is mainly used to overcome the impact of the mobile sector in the high speed of the non mobile sector, so the guide rail, wire rod requirements of some rough, as well as to strengthen the rigidity of the connection department.
(5) from materials generally speaking the Meehan the cast iron, cast iron inoculated, pouring molten iron added a certain proportion of silicon so as to change the internal structure of the iron, the curving Xian machine is more resistant to stamping, rigid have obvious progress.
