Determination of CNC machining route

CNC lathe feed processing route refers to the turning tool from the tool point (or the fixed origin of the machine tool) began to move, until returning to the point and the end of the process through the path, including the cutting path and cutting tool cutting, cutting and another non-cutting empty stroke path.

The feed route of finishing machining is carried out in order along the contour of its parts. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and empty stroke.

In CNC lathe processing, the determination of the processing route should generally follow the following principles.

1. The accuracy and surface roughness of the machined workpiece should be guaranteed.

2. The shortest processing route, reduce idle travel time, and improve processing efficiency.

3. Try to simplify the workload of numerical calculation and processing procedures.

4. Subroutines should be used for some repetitive procedures.

CNC processing procedure of aluminum profile

1: Aluminum profile cutting

Aluminum profile cutting is the most basic and common processing method in the aluminum profile CNC processing process. Because the standard size of industrial aluminum profiles is 6020mm, it is necessary to process aluminum profiles with different lengths or angles before they can be assembled into a frame.

2: Punch

Industrial aluminum profiles have a variety of connection methods and need to be punched according to different connection methods. Common punching methods include through holes and stepped holes.

• Through hole:

Mainly used for fastening connection of common bolts (half round head)

• Step hole:

It is mainly used for the fastening and connection of special connectors (internal connectors and internal connectors). It is a common and high-tech process used in the CNC processing of aluminum profiles.

3: Aluminum profile tapping

Aluminum profile tapping is what we often call tapping. The processing of the aluminum profile is to conduct thread tapping on the tapping hole at the end of the aluminum profile according to the technical requirements of the design drawings, which are used for the fastening connection of the later frame.

4: Milling machine CNC

The conventional frame assembly of aluminum profiles does not need to be processed by numerical control milling. However, in special cases, non-standard parts and profiles are used together, and when the function is expanded, the aluminum profiles need to be processed by CNC numerical control according to the technical requirements.

Advantages and disadvantages of CNC processing of aluminum profiles

1. Advantages:

• Reduce the number of tooling:

Greatly reduce the number of tooling, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of a part, you only need to modify the part processing program, which applies to the development and modification of new products.

• Stable processing quality:

High processing accuracy and high repetition accuracy, meet the processing requirements of aircraft.

• Multi variety and small batch:

In the case of small batch production, the production efficiency is high, which can reduce the time of production preparation, machine tool adjustment, and process inspection, and reduce the cutting time due to the use of the optimal cutting amount.

• Processing section:

It can process complex surfaces that are difficult to be processed by conventional methods and even process some parts that cannot be observed.

2. Disadvantages:

The disadvantage is that the processing equipment is relatively expensive and the quality of the operators is relatively high.
