This Crankshaft is based off of multiple references of different designs found online and modeled to scale using measurement diagrams.

Scene
--------------------------------------------------
- Originally modeled in 3D Studio Max 2012 and rendered using Mental Ray.
- Saved version to 3D Studio Max 2010, render results may vary.
- A Mesh only max file is included in the Max downloads with a material library
- Exported FBX, 3DS, OBJ formats are Mesh only with textures included in download.

Topology / Modifiers
--------------------------------------------------
- Topology is quads and tries, with less than 1% tries.
- Smoothing groups have been set.
- Multiple material IDs assigned.
- Turbosmooth modifier is applied with smoothing groups enabled and show only at render.

Textures / Mapping
--------------------------------------------------
- Unwrapped without any overlapping UVs
- Texturing is applied with the use of a Multi-Sub object material
- Diffuse, Specular, Gloss, and Bump maps at a resolution of 2048 x 2048.
- 7 maps
- 1 HDR image

上の画像、写真かなと思ったらCGらしい。
そのままCADデータで製作で来たら笑えるが（笑）

映像は、NASCAR用の削り出しクランクシャフト製作の様子です。
この後、焼き入れして仕上げ加工でしょうか。

Many years ago now, Mazak and Addy Machinery developed this process of CNC machining complete from solid a NASCAR crankshaft. To have a custom crankshaft in just hours vs. months was a giant leap forward for racing teams, many of which now own Mazak Integrex technology to compete and win.

The WFL M60 demonstrates it's capabilities by machining a complete crankshaft in one operation.
