CETOL 6σ- 協助你真正的解決公差問題

如何找出問題的Root Cause:

產品生產時,組件間公差的累積往往會造成無法預期的問題,因此公差分析的計算可算是相當的重要!如果能做好公差分析,就相當於對於產品的品質可以做好一定的控制。但是怎麼樣才算做好公差分析的計算呢?除了考量產品的特性需求及正確的公差分析概念之外,分析結果是否能表現出真實的狀況?我們可不可以藉由計算的結果來找出真正的問題所在?這才是公差分析的關鍵之處。

CETOL 6σ利用產品組裝的自由度特性,可表現出最真實的組裝狀態,反映出真實的結果表現。使用者透過分析結果更可以快速的找到關鍵的尺寸及真正的問題所在,可以真正的找到問題點並予以解決。

真正的解決問題 – 重型設備案例


像推土機、採礦機等大型機械設備,這類的產品有一個很有趣的挑戰。當發生問題或是需要保修時,由於設備太過於龐大(有些甚至會超過20頓重),導致運送的成本可能會相當驚人,因此在大多數的情況下,需要在設備現場進行保修工作。

為了作最有效的時間成本計算,設計者需盡可能的避免問題的發生,並且需要找到正確的問題來源才能快速的解決問題,這樣才能減少成本。我們客戶利用CETOL 6σ來作根本原因的分析,並確認問題的原因可能是什麼?工程師先利用CETOL 6σ進行分析並確定最敏感容易變化的區域在哪裡,再配合現場的故障情形及尺寸變化更新數據再重新進行計算,在幾秒鐘或幾分鐘之內就可以分析出數據。 利用分析出來的靈敏度報告,CETOL 6σ的用戶可以過濾掉部分考慮因素,並迅速且正確的識別出真正的問題根源在哪裡,可以有效的節省時間及維修成本,同時避免未來的重複保修問題。






The Benefits of DFMPro

DFMPro是專為企業量身打造的DFM ( Design For Manufacture )工具,可協助設計者及製造端建立統一的規則,並在CAD設計過程中直接進行DFM可製造性的檢查,有效的提昇效率及節省檢查時間。在產品設計及製造的過程中若能導入有建設性的DFM機制,將可為企業帶來多方面實質且有意義的幫助

知識與能力:一個專業且有經驗的企業對於市場的需求應該是相當敏銳的,因此取得正確的專業製造知識並加以累積應用是非常重要的一件事,這可以避免當設計及工程人員流動時一些專業訣竅(know-how)的損失,建立起一個專業的知識庫也有利於新進工程師的訓練,他們可以遵循已建立的製造規則來作設計並同時學習。

節省成本:降低成本是非常重要的一件事,DFMPro工具可協助減少和避免廢料的浪費及昂貴的模具費。

節省時間:避免沒有效率的工作可以加快產品上市的時間,一般時程會造成延誤,主要常見的原因之一是Rework,但藉著利用DFMPro工具作檢查,這樣的失誤將可以盡可能的被避免,除此之外,人工的檢查需耗費大量的時間且沒有效率,透過自動化的DFMPro工具來檢查,將可大大的減少時間的浪費。

品質:DFMPro工具可以累積經驗教訓並改善設計,避免重複出現品質的問題

客戶的話:
“ 現在我們產品的3D資料都會在設計的過程中利用DFMPro工具來進行檢查,以往我們的方法是靠設計者本身來作檢查,但是這種方法太過於浪費時間。相對的,現在利用DFMPro工具來檢查需要設計變更或修改的部份,它是非常的迅速而且可靠的,而且這些檢查的準則可以根據產品來作一些適當的調整。因此,在圖面發佈之前,我們成功的減少了75%的檢查時間(肉厚的檢查),並提高了設計改進的效率及效益。”

HDR Light Studio 3.0 隆重登場

Lightmap launches HDR Light Studio v3.0
HDR Light Studio v3.0 features: Collada support, new light blending modes, custom fall-off curves and faster render times






Leicestershire, England – 1st January 2012 – Lightmap today announced immediate availability of HDR Light Studio v3.0 – the most incredible version yet of their groundbreaking real-time lighting software. Packed with new features including; localized exposure, color and saturation tools using new light blending modes, custom fall-off curves, a new color system for lighting artists and Collada support. None of these new additions are at the expense of performance; HDR Light Studio v3.0 features even faster render times with all parameters now supporting instant feedback.“The new blending modes for lights in version 3.0 are awesome,” enthuses Bruce Bigelow, Creative Director and Partner at Electric Art, “…because you can dodge and burn huge areas of hi-res HDRI backgrounds instantly and with an incredible smoothness you can't achieve in any other software. With the new custom fall-off curves, new light shapes are infinite. It's a quantum leap from 2.0.”
HDR Light Studio v3.0 provides market leading, real-time non-destructive manipulation and generation of HDR environments. Significant updates to HDR Light Studio 3.0 include:
• New Light Blending Modes: use light sources to adjust exposure, color and saturation.• Custom fall-off curves: fine control over synthetic light fall-off.• New color system: Color selection and analysis tools designed specifically for lighting artists to allow precise color matching and auditioning.• Collada support: LiveLight now supports Collada to allow the import of geometry and camera information from all major 3D modeling packages.• Increased Performance: Faster rendering times and all features now support real-time feedback.
HDR Light Studio v3.0 can slash the time needed to professionally light CG (computer generated) scenes, “Usually, when you’re updating software, you’re disappointed by a lot of features that are totally useless. But with HDR Light Studio v3.0, the team is really listening to what the users are saying,” explains Piotr Kolus, Lead 3D artist at Ars Thanea. “All the new options are boosting your lighting process. From simple changes to advanced new features - all of them are more useful than I expected.”
HDR Light Studio is a proven lighting toolkit that can be used stand-alone by importing 3D scenes into LiveLight, or used in conjunction with any number of Live plug-in partners, including KeyShot, Maxwell Studio, Deep Exploration, VRED and Patchwork3D. This helped position HDR Light Studio as a professional, world-class, image based design suite. Version 3.0 ups the ante even further, “The new blending modes in v3.0 are game changing additions to HDR Light Studio. The ability to fine tune exposure, color and saturation within the software is invaluable. It can make the difference between a nice image and an amazing one,” according to Greg Peruski, CGI artist at Mid Coast Studio. “I also appreciate the ability to place a back-plate image in the LiveLight window now. It makes the process of lighting more intuitive... Being able to see your lighting in context with the back-plate is a huge benefit.”
Typical scenarios in which HDR Light Studio v3.0 can produce incredible results whilst saving time and money include:
• Professional Studio Lighting - design traditional studio lighting rigs using powerful Synthetic and Picture based light sources quickly, efficiently, and with a quality of output not possible in other software.• On Location Professional Studio Lighting -load existing HDR environments and augment these with additional light sources to bring out the best in your subject matter.• Color matched lighting for back-plate images -create lighting to bed CG objects into existing backgrounds using HDR Light Studios' color analysis and selection tools.• Creative HDR location re-lighting- artistically enhance and relight existing HDR environment maps to creatively change the feel and mood of an original HDR in a non-destructive manner.• Increasing the dynamic range of LDR environment maps- extend the dynamic range of existing HDR and LDR* images using dodge and burn techniques with the new light blending modes.
*LDR images must be in exr or hdr formats.HDR Light Studio: What's New in Version 3Shine a light into existing HDR locations with the new Blend modes










Use synthetic light sources to make adjustments to the underlying content - be that other lights or existing HDR locations. These new blend modes provide totally interactive control over the lighting from existing HDRI environments. Blend modes can be used in conjunction with the 'Inv' button to reverse their effect.





Precise control to shape the light - Custom Fall-off










Use the powerful custom fall-off ramp to control the graduation of light precisely across its fall-off shape. This provides more subtle studio lighting effects than ever - allowing precise control of how graduations of light will appear in reflections. Custom fall-off also provides users with the ability to precisely control the areas adjusted by the new light blend modes.





Color Gradients - Synthetic and Picture Lights






Why should a light have only one color? Now you can create a ramp of color from the center to the edge of a synthetic and picture light. The effect can be subtle or outrageous. You can also use the color gradient to control the brightness across a picture light, like a fall-off ramp, ideal for fine control of Soft boxes.





Advanced Color Picker - Designed for lighting artists






We designed a new color picker focused on the the needs of a lighting artist. The color refinement grid allows artists to try subtle changes in color to see their effect in real time. The color matching tools let users match color from HDR and LDR images, plus there's a Kelvin Color Temperature picker - an essential ingredient for lighting








LiveLight - faster and full of new enhancements







LiveLight is now faster with an improved render engine.
Added support for loading Collada files into LiveLight - including multiple cameras.
Select your camera views from .mi and Collada files containing multiple cameras.
Metallic reflection mode has been added.
Floor Shadow - grounds a model giving it a more realistic feel, without the need for importing floor geometry that blocks light and reflections from the HDRI.
Choose an image (JPEG, TIF, BMP) or a solid color for the LiveLight background.
Tone-mapping has been replaced with a gamma setting.





General improvementsGeneral
It's all real-time - a far more interactive experience! Every setting in HDR Light Studio 3.0 now updates the HDR canvas in real-time. Adjust a light color, the background gradient, HDR background rotation or brightness - and instantly see the results without waiting to press OK.
HDi project files now have an icon in Windows, and can be double clicked to open them in HDR Light Studio.
Main Interface
Re-name lights - double click a light in the list to re-name it.
Picture Lights are given their Picture Light name - but can be re-named afterwards.
Click and drag lights up and down the light list to easily re-order them.
Hover over a light in the list and a cross appears on the HDR canvas showing the location of that light, making it easier to identify your lights.
The light visibility states are now saved in the HDi project files.
HDRI Background Settings
Fine tune the HDRI rotation with both Degree and Minute precision.
Colorize your HDRI background - ideal when used with studio background images to create any background color from a single grey-scale HDRI.
Flip - now you can flip the referenced HDRI horizontally.
