What is the best way to determine the exact process elements? Designers and buyers must see the communication and clicks.

Avoiding the treatment of aimaisa and back of hand! In this publication, the main items such as material, tolerance, heat treatment, surface treatment, etc. of the processing programme for designers and buyers are discussed, and the customer's information is correctly understood and realised.

Process engineering elementsComposition: Correct communication and correct processing for the first time.

Hajime: "Many problems of mechanical processing are caused by the lack of clarity of the elements. The first step towards a successful project is to make the engineering elements clearly documented. "

I. What is included in the complete list of requirements for the programme?

(リスまたは表で表示)

Basic information: part number, name, バージョン.

Material: Blank, specification, specification number (Example: 6061-T6 Aluminium bar, GB/T 3191 based).

The main elements of dimensioning and geometry: tolerance specifications (ISO 2768-m, etc.), special tolerances for important dimensions, shape and positional tolerances.

Surface treatment: Surface roughness (e.g. Ra 1.6), mesh (e.g. hard chromium mesh, thickness 10-15 μm), anodic acid treatment (colour, film thickness), sandblast, etc.

Heat treatment: Back to HRC28-32, charcoal-immersed oxidation.

Other Special Requirements: Barry Taking Standards, Cleaning, Packaging, and Labelling.

Secondly, it is possible to efficiently transmit the elements to the machine shop.

(3D Models (STEP form) + 2D Drawings (PDF/DWG) + Project Requirements (PDF) recommended)

III. Examples of Treatment Problems Arising from "Uncertainty of Elements

(Causes 1: "Smooth surface" and "Shikaribetsu", consistency in the understanding of roughness is not a problem. (Causes 2: Heat treatment designation is not necessary, and it will be deformed after that)

Conclusion and CTA: Specific requirements are the beginning of collaboration. In this case, the requirements are strictly applied at the production site, and the mechanical processing plant in Pro is also working on the requirements for the specifications of the processing process (Link to Memory V).

YOKUARU QUESTION

"The surface roughness of Ra 3.2 and 1.6 is seen as an offence?" (Answer: Comparison of the surface roughness of Ra 1.6 is clear and slippery, while the surface roughness of Ra 3.2 is small and visible.)

"On what occasion is it necessary to specify the material specification number?" (Answer: On parts with important properties, it is necessary to ensure consistency of material composition and properties. (Answer: For parts with important performance, we recommend the designation of parts to ensure the consistency of material composition and performance.)
