将零件上传到FICTIV平台时，您可以获得可制造性（DFM）反馈的即时设计。以下是为什么您收到的那种反馈以及您可以做些什么来让您的部件准备好的解释！

Fillets to be added

显示圆角添加到零件的图形

Explanation

圆角将被添加到尖锐的内角或起草或倾斜边缘符合锋利边缘的区域。否则，这些功能无法机器。

Action Step

If you want to specify radii on your fillets, you can add them to your design. Otherwise, the manufacturer will use their discretion to add fillets to these areas.

Fillets to be increased

一个图形显示在每个部分旁边的2个部分，左侧部分有一个小的半径圆角，带红色x着色红色x，右侧有一个大的绿色阴影圆角，绿色复选标记

Explanation

设计为您的部件的圆角太小而无法使用否则是必要的最小的端铣刀。这为CNC加工程序添加了额外的工具和刀具更改操作，将时间添加到整个项目。

Action Step

No action required, unless you want to change the fillets to be a specific size. Otherwise, the machinist will increase the fillet size to avoid using an extra tool.

洞深度（钻孔）

在左侧，钻孔的部分大于12d和红色x，右侧的孔孔小于12d和绿色复选标记

Explanation

If the depth of a hole in your part is greater than 12x the nearest bit diameter, we will not be able to machine your part. Drills that are greater than 12 times the diameter of the bit are hard to source and may break during drilling. If you increase the diameter of the hole, a larger drill can be used, which would mitigate the issue.

Action Step

If the hole is a blind hole and is too deep to be drilled, you can try to decrease the depth of the hole or increase the diameter of the hole. The ratio of depth to diameter needs to be less than 12.

Depth of cut (milling)

on the left, a part with a deep pocket labeled as greater than 10D and the tool is bending. on the left a part with a pocket that is less than 10D and the tool is straight

Explanation

If the depth of a feature in your part is greater than 10x the diameter of the end mill used, we will not be able to machine your part. End mills that are greater than 10 times the diameter of the bit are hard to source and may break during use. This may occur if you have thin but deep features such as slots or grooves.

Action Step

If you can, decrease the depth of the feature. Otherwise, increase the feature diameter or the corner radius (fillet), which will allow a larger diameter tool to be used. This in turn allows a longer tool.

Non-standard thread (produced at risk)

Explanation

The fit/function of this thread size cannot be guaranteed because we cannot source a proper thread checker. We can still move forward with manufacturing your part, but it will be a High Risk Product.

Action Step

In order to guarantee the fit and function of your threads, you can select a standard thread size.

Thin walls may not hold up to machining

左侧的一部分薄而较薄，与工具接触弯曲，在右侧部分厚，而不是与工具接触的弯曲

Explanation

对于金属的最低要求厚度为0.25mm，塑料为0.50mm。如果墙壁比这更薄，它们不会坚持制造过程。材料可以完全经过翘曲，变形或打破。要继续制造，您将不得不更新墙厚度以上最小。

Action Step

The minimum required thickness is 0.25mm for metals and 0.50mm for plastics. Update your design to be above the minimum thickness of your material.

如果删除过多的材料可能会出现翘曲

Explanation

Removing a large amount of material from a part puts a lot of stress on the workpiece, causing warping when the part is removed from the machine.

Action Step

Evaluate the design of your part (is it best suited to CNC machining?) and the geometry of the final part (thin walls). Add to the wall thickness or consider changing the manufacturing process.

Not optimized for CNC machining

Explanation

Your part is not optimized for CNC machining. Significant changes must be made for it to be manufactured.

Action Step

Chat with a Fictiv representative to learn more about why your part failed for CNC machining.

Part will be reworked from McMaster part number

Explanation

您的部分将由特定McMaster部件号制造。这可能是从McMaster购买的库存材料。

Action Step

你不需要做任何事情,unless you have issues with the part number listed. In that case, contact your Fictiv sales rep.

手动去毛刺可能是必要的

具有内部倒角和拆检工具的矩形零件

Explanation

The highlighted areas may be deburred manually due to reachability constraints or the necessary tool geometry required. Some areas may have chamfers that are not accessible with standard tooling. In this case, these areas will be deburred manually.

Action Step

If you don’t want these features to be deburred manually, you can remove the chamfers from your CAD model.

Thin stock not available for chosen material

Explanation

Due to the part thickness, this part must be made from stock thickness material. However, the thinnest material available is too thick. If we do machine with your desired thickness, the part will end up warped or out of spec.

Action Step

使用备用材料重新配置您的部件（在您的DFM反馈中建议）。您还可以与FICTIV REC聊天以获取更多建议。您还可以将设计的厚度更改为可用于所需材料的最小厚度。

Non-matching drawing and CAD model

a graphic showing two parts, one says CAD and the other says 2D with a red x

Explanation

CAD模型与您提供的2D绘图不匹配。

Action Step

If your CAD model is correct and you don’t need a 2D drawing, you can simply remove the 2D drawing. Otherwise, you can upload the correct CAD model that does match the 2D drawing. You can also generate a 2D drawing right on Fictiv’s platform.

Material mismatch

用于材料选择的窗口显示2024突出显示，而图形表明该材料是7050铝，其间具有红色x

Explanation

您的材料配置与您的2D绘图不匹配。我们无法使用此相互矛盾的信息使您的零件。

Action Step

If your drawing states the correct material, reconfigure your part with the correct material. Otherwise, annotate your drawing to cross out the material and make a note of the correct material.

Unreachable volume

一个图形，显示一个具有悬垂功能的2D对象和工具旁边的红色x

Explanation

使用标准工具无法完全访问此功能或可加工。无论是太深，它是否以某种角度或被另一个特征阻挡。

Action Step

In order to make the feature(s) machineable, please update your model so that the necessary features are reachable. Talk to your Fictiv sales rep for more details.

EDM可能会限制发出时间选择

Explanation

由于设计，该功能将加工电气放电加工，因此只能在海外生产。这可能会限制提前期选项。

Action Step

If you require a different lead time or to manufacture domestically, please update your model so that it can be machined using standard tooling.

Gear hobbing may limit lead time options

Explanation

This feature will be machined using gear hobbing, so it can only be produced overseas. This may limit the lead time options.

Action Step

If you require a different lead time or to manufacture domestically, please update your model so that it can be machined using standard tooling.

Tight tolerance plastics

当公差小于0.10mm时，具有容差带和警告标志的零件

Explanation

不能保证低于0.1mm的粘度下的紧张公差。由于加工时，塑料材料可以通过温度变化而翘曲，因此我们不能容纳低于+/- 0.05mm的公差。PEEK具有温度变化的最佳尺寸稳定性，如果您的紧张耐受性至关重要，可能是一个很好的替代方案。

Action Step

如果您无所作，零件仍将加工，但我们无法保证严格的公差。如果这些公差至关重要，您可以将材料更改为PEEK。
