What processing steps are required to process CNC lathe parts?

1. Create a CAD model: The CAD model is used to generate the CNC code for the CNC lathe.

2. Generate CNC code: CNC code is the instructions that a CNC lathe follows to create a part.

3. Set up the CNC lathe: Before starting the machining process, the CNC lathe must be set up with the proper tooling, workholding, and other necessary components.

4. Machine the part: The CNC lathe is programmed to move the cutting tool along a defined path to create the desired shape.

5. Quality Control: Inspection of finished parts to ensure they meet required specifications.

6. Finishing: Parts may require deburring, polishing, or coating for final finishing.

(1) Material and heat treatment requirements

The material and heat treatment requirements given on the drawings are the basis for selecting tools, CNC lathe models and determining the amount of cutting.

(2) Geometric conditions constituting the contour

In turning manual programming, the coordinates of each node are calculated; in automatic programming, all geometric elements that make up the contour are defined. so point

Pay attention to the analysis of the graph:
of
1 Whether a certain size is missing from the product drawing, making its geometric conditions insufficient and affecting the contour composition;

2. Is the position of the line on the product map blurred or the size is not clear, resulting in the inability to program;

3 Whether the geometric conditions given in the product diagram are unreasonable, resulting in difficulties in mathematical processing.

4 The dimension marking method of the product drawing should adapt to the characteristics of CNC lathe processing. Dimensions should be marked according to the same datum or coordinate dimensions should be given directly.

(3) Dimensional accuracy requirements

Analyze the dimensional accuracy requirements of the pattern, determine whether the turning process can be used, and determine the process method to control the dimensional accuracy.

During the analysis process, dimension transformations such as incremental dimensions, absolute dimensions, and dimension chain calculations can also be performed simultaneously. Use CNC lathe

When cutting, the average value of the maximum and minimum limit dimensions is often taken as the programming dimension.

(4) Shape and position accuracy requirements

CNC lathe processing parts are more convenient than traditional CNC lathes in terms of raw material shape and position accuracy, and the standards are looser. given shape

Geometric tolerance is an important basis for ensuring accuracy. The positioning reference and measurement reference determined according to the needs during processing can also refer to the special CNC lathe.

Some technical processing is required to effectively control the shape and position accuracy.
