Background and core objectives of the issue

The precise CNC component selection 6061 or 7075 aluminium alloy is concerned with the balance between strength, corrosivity, processing, surface treatment and cost. For custom CNC parts, size is only the basis, and the real goal is to stabilize the parts in assembly, operation and repeated procurement.

In assessing the project, the purchaser should not only compare the unit price and period, but also confirm whether the supplier understands the balance between strength, corrosivity, processing, surface treatment and cost, and whether it can provide evidence of DFM recommendations, process records and traceability. Clarity of functional priorities can reduce unnecessary high-precision requirements and avoid flooding critical requirements by ordinary dimensions.

Chart requirements and functional features

The drawing shall identify the material plate number and state, the main baseline, the critical dimensions, the public transport, the surface roughness, the margin treatment and the final acceptance state. The balance between strength, corrosivity, processing, surface treatment and cost requires a focus on characterizations that directly affect assembly and performance, and indicate whether the requirements are to be checked after machine processing or thermal treatment, surface treatment or cleaning.

The 2D drawings and the 3D model must remain in the same version. For holes, collages, seals, screws, or appearances, they should be supplemented with measurements of location, baseline relationship, and permissible status.

Processing routes and process control

The recommended manufacturing route is to select the number and status of the plate according to the load and the environment, and to match the stable cutting parameters. Process planning should, to the extent possible, allow key features to be performed in a uniform baseline and in fewer packages, with clear rules for knife life, tightness, cutting heat, dust and intermediate testing.

Once the material, equipment, packaging, procedures and testing methods are approved, they should be subject to version control; any change in the balance between the intensity, corrosivity, processing, surface treatment and cost of impact should be reassessed and confirmed before the bulk continues.

Common risks and preventive measures

The main risk of the subject is that the selection of materials by strength alone may ignore the differences in the anode oxidation, stress and supply status. Often, such problems are not immediately exposed on a single size, but occur when assembly, surface treatment or batch overlap.

Precautionary measures should include the identification of those responsible, inspection nodes, and unusual response rules.

Method of detection and basis for acceptance

The following acceptance and inspection methods are recommended: verification of proof of material, hardness, size stability, and post-treatment appearance. The detection method must be consistent with the drawing definition, and resolution and uncertainty should be measured to meet the commons requirements; for complex baseline relationships, priority should be given to the provision of characterization reports, rather than to simple qualified conclusions.

If the customer and the supplier use different equipment or methods, agree on the matching rules prior to production.

Recommendation for implementation of request for quotations and volume

The request for quotation information shall contain at least 2D drawings, 3D documents, materials, quantities, key public transport, surface treatment, application instructions and target exchange periods, with, inter alia, a balance between strength, corrosivity, processing, surface processing and cost. The more complete the information, the more reliable the process assessment, quotation and submission judgement.

Repeated orders do not default that all conditions remain the same, and the drawing version, quantity, material supply and processing requirements should be reconfirmed.

Project evaluation: Please send 2D drawings, 3D documents, materials, quantities, key public transport, surface treatment and application requirements to chenyongxing@xc-cncprecision.com, for which we can provide the DFM evaluation.
