                Some knowledge of CNC four axis machining

                Release time:2018-12-07 11:41:51  Browse times:

                Confirmation of CNC four-axis machining path.

                CNC lathe feed processing path refers to  the turning tool moves from the start of the tool point (or machine tool fixed origin) until it returns to the point and finishes the process.The path includes the path of machining and tool cut in, tool cut out and other non-cutting empty travel path.

                The feed path of fine machining is basically carried out along the contour of its parts.Therefore, the key to confirm the feed path is to determine the feed path for the rough machining and empty stroke.

                The confirmation of machining path generally follows the below principles in CNC lathe machining:

                ① To ensure the accuracy and the surface roughness of the workpiece.

                ② Make the processing path shortest, reduce the empty travel time, improve the processing efficiency.

                ③ Try to simplify the work of numerical calculation and the procedures of machining.

                ④ For some repetitive applications, subroutines should be used.


                Advantages and disadvantages of CNC four-axis machining.

                CNC machining has the following advantages: 

                ① No messy tooling is needed to process shapeless parts,If you want to change the shape and size of the parts, you only need to modify the parts processing procedure, which is suitable for the development and modification of new products.

                ② Stable processing quality, high accuracy processing.Adapt to processing aircraft requirements.

                ③ Production efficiency is higher under the condition of multiple varieties and small batch production.It can reduce production preparation, machine tool adjustment and process inspection time, and reduce cutting time due to the use of optimal cutting volume.

                ④ It can process the messy surface which is difficult to process by the convention method,It also even can process some position that cannot be observed.

                The disadvantage of numerical control machining is that the machine tool equipment is expensive, requiring repair personnel to have a higher professional level.
