Prototype structural machinability refers to the design prototype on the premise of meet the
requirements,create the feasibility and economy.Below will analysis the prototype structural
machinability from the two aspects of mechanical processing and assembly .
Mechanical processing requirement to the prototype structure
1.To facilitate the clamping. The prototype structure should facilitate the positioning and
clamping when processing, the clamping number is less. Decodes the top clamping and
lathe dog are easy to device holder, but this structure is not convenient to the clamping.
-
2.To facilitate processing. The prototype structure should adopt standard numerical as far
-
as possible,so that can use the standard tools.At the same time also pay attention to the
-
engage and retract , easy to guarantee the machining accuracy, reduce the machining
-
area and hard process surface, etc.
-
3.To facilitate CNC machine programming. The CNC machine process machinability
-
problems involve very wide, if the machining programming is convenient or not is the
-
indicator of scale the CNC technology . The dimensioning methods on the prototype
-
drawing has a big effect to the process.So should put forward different requirements
-
to the prototype drawing, all need to the CNC machining prototype,the data given by
the drawing need to conform the principle of convenient programming.
