Common ways to eliminate internal stress are to use natural or artificial aging and vibration treatment。Secondly,Pre-machining of workpieces excess material,Natural aging for 1-2 hours before processing and shaping,It can also eliminate deformation caused by internal stress
Milling of thin-walled aluminum parts with poor rigidity,The following clamping methods can be used to improve processing accuracy:Use vacuum suction cups to clamp workpieces for evenly distributed clamping force;Use the method of filling media inside the workpiece to improve the rigidity of the workpiece
Knife material、Geometric parameters、Tool structure has an important influence on cutting performance,Correct choice of tools,Essential for improving dimensional stability in processing
The CNC high-speed cutting process is generally:Rough machining – semi-finishing – corner cleaning – finishing and other processes。For parts with high precision requirements,Need to increase the number of semi-finishing operations,and retain a uniform machining allowance
Choose the right feed rate、Spindle speed and depth of cut;
Use symmetrical processing method for the front and back sides of the workpiece,Avoid centralized processing which is not conducive to heat dissipation;
Avoid thin walls
Same as high features,Vibration increases when machining thin features。as a guide,The minimum thickness of metal thin-walled parts is 0.5-0.8mm,The minimum thickness of plastic parts is 1.0-1.5mm。If the wall is used for supporting or higher features,The wall thickness should be increased,To avoid vibration during processing
Avoid small or raised text
You may need to mark the part with the part number or company name,Adding text looks cool,But processing is very time-consuming,Electrochemical etching or laser engraving is usually better。If you must mill text,Choose sunken rather than raised text whenever possible,Keep it simple with larger text,Font depth does not exceed 0.3mm
Adhere to thread standards
When creating threads,It’s also important to stick to standard sizes。The larger the thread,The easier it is to process。The length should be kept to a maximum of the nominal diameter of the hole 3 times。For blind hole tapping,It is best to add at least at the root of the hole 1/2 Extra length of aperture。You may also consider using inserts,Threaded coils and copper nuts last longer than bare machined threads,Especially in materials like aluminum or plastic,and easy to install
The largest possible interior angle
Any internal cuts will create fillets,It is half the diameter of the tool used。Milling with smaller tools takes a long time,We recommend that the radius should be larger than the machining depth 1/3。The best approach is to eliminate interior corners or allow the largest possible interior corner radius in the mating part design,and use the same radius on all inner edges,so that the same tool can be used throughout the process
Avoid too deep cavities、Grooves and deep holes
The depth of the pocket and groove is usually related to the diameter of the tool used to machine the internal fillet.,A good rule of thumb is to keep the pocket depth equal to the tool diameter 3-4 times,Or the groove depth is smaller than the feature width 4 times。Whether blind hole or through hole,Recommended maximum depth is diameter 4 times,The minimum aperture is 1 mm,And it is recommended to design standard size holes。Use a standard drill bit,Can process holes quickly and with high precision;For non-standard holes,Using end mills increases costs
