Background and core objectives of the issue

3 plus 2 locator processing completes the three-axis cut at a fixed angle, while the five-axis motion allows the blades to change continuously in the cut. Both reduce the load, but apply geometry, programming risks and costs.

The choice is based on slant-faced, warp-continuing, knife availability, surface cutter marks and batches. The purchaser should place the functional failure, assembly relationship and consistency of duplicate orders prior to the unit price comparison and confirm at the quotation stage whether the supplier is able to provide DFM, process records and traceable testing data.

Chart requirements and functional features

The drawings and models should indicate key angles, contours, blade-direction limits and areas where no slash is allowed and establish a uniform baseline.

Key dimensions should indicate which state of acceptance is after machine processing, thermal or surface processing; and, if there are many understandings, a written list of questions and confirmation should be formed prior to preparation and programming.

Processing routes and process control

The rules prioritize assessment of 3 plus 2 on the slopes and multiple-direction holes; and the five-axis movement on the blades, wheels or convoluted sides and the optimization of attitude through machine-bed exercise.

The first of the CNC manufacturing technology projects, which corresponds to the 3+2 positioning process and the 5-axis, needs to represent the true mass conditions.

Common risks and preventive measures

Unnecessary association increases the programming and collision risk, and 3 plus 2 leaves a cutter or cumulative angle error if the partition is unreasonable.

With regard to the risk of 3+2 positioning processes and 5-axis interaction, preventive measures should identify those responsible, check nodes and unusual reactions.

Method of detection and basis for acceptance

Simulation of the process and interference with machine-beds, with the first one using the CMM scanning angle and contours, will focus on comparing the transitions in the processing regions.

The electronic report recommends that parts numbers, drawing versions, batches of materials, equipment numbers, inspection dates, actual results and determinations be retained to facilitate customer review and subsequent batch comparisons.

Recommendation for implementation of request for quotations and volume

The request for quotations will provide complete 3D models, critical curves, production, materials and permitted slash locations to facilitate the selection of economic processes.

Once 3 plus 2 positioning processes and how to select the five axes are duplicated, you shall keep the approved samples, controlled procedures, packages, knife life, batches, first and unusual records.
