What are the machining principles of the machining center?

Machining principles of Machining Center. 

Determination of processing route. 

The feed path of CNC lathe refers to the path through which the turning tool starts to move from the point of alignment (or the fixed origin of the machine tool) to return to that point and ends the machining program, including the path of cutting and non-cutting empty stroke paths such as tool cut-in and cut-out. 

The feed route of finishing machining is basically carried out along the outline of its parts, so the focus of determining the feed route is to determine the feed route of rough machining and empty stroke. 

In the machining of NC lathe, the determination of machining route should generally follow the following principles. 

(1) should be able to ensure the accuracy and surface roughness of the machined workpiece. 

(2) make the processing route shortest, reduce the empty travel time and improve the processing efficiency. 

(3) simplify the workload of numerical calculation and simplify the processing program as far as possible. 

4 for some reused programs, subroutines should be used.

Advantages and disadvantages. 

NC machining has the following advantages: 

(1) greatly reduce the number of tools, machining complex parts do not need complex tools. 

If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification. 

(2) the machining quality is stable, the machining precision is high, and the repetition precision is high, which can meet the machining requirements of aircraft. 

(3) the production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of cutting quantity. 

(4) the complex surfaces which are difficult to be machined by conventional methods can be machined, and even some unobservable machining parts can be machined. 

The disadvantage of NC machining is that the machine tool equipment is expensive and requires maintenance personnel to have a high level.
