First, consider the manufacturing lot size of the part.
If you are manufacturing a part in large quantities, you should fully consider the positioning parameters used in the machine tool fixture, and the "excess" factors such as the process hole.
Second, consider the characteristics of the part forming method
For example, when a high-speed rotating disc part is used for casting, there are inevitably defects such as loose tissue or pores, and such process features are not subjected to post-balancing treatment, which inevitably leads to excessive growth in high-speed operation. The centrifugal force will indirectly lead to bearing heat, abnormal noise and short life. For example, when the carbon cutting material of the medium carbon steel or the high carbon steel material is used to obtain the blank of the part, the cutting portion is easily quenched.
Third, consider the material properties of the part
For example, a sheet-like sheet-like part, we first think of using iron plate to take material, of course, the way to take the material can be laser cutting / water cutting / flame cutting / even wire cutting / or stamping. This is determined by the best economics of the part. Of course, whether it is for sheet metal or wire, whether it is sawing or cutting or flame or laser or water cutting. Pay attention to the problem of nesting. (pursuing the maximum utilization of materials)
Fourth, consider the processing fixture of the part
For single-piece small-batch manufacturing, it should be avoided in the design when it is impossible to process on a general-purpose machine tool, and it is necessary to use a special fixture for production and processing.
Fifth, consider the tool that makes the part.
When designing a part, consider the tools that are commercially available and suitable for the clamping and use of your own machine. Try to avoid custom non-standard tools. This section requires a brief understanding of the national standards for some tools. For example, you have designed a hole in the part, and this hole has a higher cylindricity and finish requirements. Generally, the process for the hole is drilling or hole-reaming or boring-- or internal grinding. However, if the diameter value of your hole is not close to the first or second series of tools, it will become very troublesome if you can't buy the corresponding tool such as the drill reamer in the standard tool market.
Sixth, consider the processing range of the machine tool that processes this part.
Machine tools have a fixed range of processing capability parameters. For example, the C6132 means that the horizontal turning machine can achieve a maximum part turning diameter of 320. The M7130*1000 represents a horizontal axis table surface grinder with a single-clamping grinding width of 300 and a length of 1000. Therefore, when designing parts, it is necessary to combine the machine parameters to consider the clamping or machinability of the machining machine.
Seventh, consider the gage
Part manufacturing has been completed requiring the use of universal gages and gages for measurement. For example, if you design a set of conical fittings, you don't choose the standard Mohs series or the commonly used taper like 7:24 taper or 1:50, instead of getting a taper of 7:23 or 1:47, then it is standard. The standard gauge taper and taper sleeves are not available in the gauge market. Of course, if the parts using the two-dimensional projection detection or the three-coordinate detection are not within the constraints of this situation.
Eighth, consider heat treatment requirements
For some newcomers, when dealing with parts that require high wear resistance or require good comprehensive mechanical properties, such technical requirements often appear on the drawings. Material Q235—hardened hardness reaches HRC60, and Ensure uniformity of hardenability and hardness. Material 45# steel - after quenching and tempering up to 58HRC. For such phenomena, it is recommended that you go over the knowledge of metal materials and heat treatment.
