The feed processing route for CNC finishing mainly refers to the movement of the turning tool from the origin fixed to the machine until it returns to the origin and ends the path the machining program passes. Including the cutting path, non-cutting empty path such as cutting and cutting of the tool. The feed route of CNC finishing is basically carried out according to the contour sequence of the parts. Therefore, the focus of the work for determining the feed route is to determine the feed route for finishing and empty travel.
The main principles of CNC finishing
1. Ensure the precision of the workpiece being machined and the roughness of the surface.
2. Reduce the idle travel time in the feed route to make the processing route the shortest, thereby improving the processing efficiency.
3. Simplify the workload of numerical calculation as much as possible and simplify the processing procedure.
4. For some re-use programs, try to use subroutines.
CNC machining center environment
The machining center should be installed away from sources of shock, away from direct sunlight, without heat radiation and without moisture. If there is a source near the place where the machining center is installed, a vibration proof ditch should be installed around the horizontal machining center. If you do not set a shockproof ditch will directly affect the machining accuracy and stability of the horizontal machining center, time will affect the poor contact of electronic components, failure, affect the reliability of horizontal machining centers.
CNC controlled precision voltage and current control
Machining centers are generally installed in the processing plant, and the processing plant has a large number of mechanical equipment, which inevitably leads to large fluctuations in the power grid. Therefore, the position of the horizontal machining center must strictly control the voltage and current of the power supply. The voltage and current of the power supply must be controlled within the allowable range of the horizontal machining center. The voltage and current of the power supply must be kept stable, otherwise it will directly affect the position. Machining center work.
Numerical control precision machining normally operates under a temperature of less than 30 degrees Celsius to operate normally. Under normal circumstances, a horizontal fan and a cooling fan are installed in the distribution box of the horizontal machining center to ensure that the electronic parts and the central processing are at a constant temperature. Working under state. If the temperature and humidity are too high, the component life of the control system will be reduced.http://www.pump-casting.com/
