First, non-standard parts processing to improve the level of processing technology
1) CNC programming optimization:
Clever use of the inherent program, flexible use of the main program and subroutine, to ensure the consistency of non-standard parts processing size and improve processing efficiency.
Non-standard parts machining to minimize the cumulative error of the CNC system, using absolute programming, so that each program segment is based on the origin of the workpiece.
2) Reasonable setting of processing route and sequence:
Optimize the feed mode, select the appropriate feed mode according to the workpiece's manufacturability requirements.
Select the appropriate processing trajectory, such as milling the external outline of the plane workpiece, as far as possible along the extension line of the contour curve cut, to avoid the intersection of the knife mark.
3) Tool selection and installation:
The principles of tool selection include easy installation and adjustment, good rigidity, durability and high precision.
The determination of the cutting parameters is also the key, rough machining takes a larger cutting depth to reduce the number of tool trips, and fine machining takes a smaller cutting depth to obtain a higher surface quality.
Second, non-standard parts processing to introduce efficient processing methods
1) Innovative processing strategy:
For example, when disassembling non-standard precision mechanical parts in the vice mouth, the parts are prevented from being pinched by machining the soft jaws.
When using magnets to collect small precision mechanical parts, first let the magnet attract a piece of iron plate to improve the collection efficiency.
2) Application of special tools and equipment:
For the problem of slippage when the pulley is driven with the axle, a special drill can be used to mark the socket on the axle to increase the adsorption force.
For the deformable workpiece, the strategy of first clamping and then positioning is adopted to limit its freedom by finding 6 anchor points.
Third, improve the management model and introduce intelligent manufacturing
1) Improve the management model:
Improve the efficiency of production schedule and logistics management through software upgrade or introduction of management center system.
Coordinate supply chain to ensure smooth cooperation between materials and personnel.
2) Introduce intelligent manufacturing:
Use the Internet of Things technology to connect devices and electronic systems to communicate production status and problems in a timely manner.
Improve the transparency and informatization of the production process through data and artificial intelligence analysis, and ultimately achieve the purpose of improving production efficiency.
