鑄造原物料價格的崩跌
曾幾何時,在2008年的前半年或者我們可以說在北京奧運之前,不管是生鐵也好,焦碳也好,鐵合金也好,耐火材料也好,各種與石油產業有相聯結的鑄造化學品也好,看到的都只有四個字"欣欣向榮",價格不斷的漲-漲-漲,但就在最近(應該是奧運結束後),好像坐雲宵飛車一樣,讓人措手不及的溜了下來.真的在鑄造廠就可以感覺到這股氣氛,上游的機械廠開始減少下單量,以慢慢去化原來為避免價格過大波動而多準備的庫存,而鑄造廠則因產能遠大於目前的市場需求(demand)而拼命的在外頭殺價搶單,事實上原物料可能都還沒有下降這麼多呢,但鑄件的售價則已是一瀉千里.在這個情形下可以真正受惠的廠商應該是少之又少吧.~續

STL檔案格式問題
基本上來說,STL已經是模流軟體在計算時不可或缺的一種檔案. 在SOLIDCast軟體使用上, 我們只能接受Binary格式的STL.主要的目的是縮小檔案的大小,藉此提高運算的效率.換句話說,越小的模型檔就可以擁有更短的計算時間.
那我們如何取得Binary STl 檔案呢? 通常3D的CAD軟體在輸出(export) or 另存新檔時, 就會詢問要存成bin或ASCII的格式,在此時我們就可以直接選擇.若你所使用的軟體只能提供ASCII格式的STL,我們在SOLIDCast中也提供程式可以在ASCII轉Binary的格式,步驟如下:
(1)開啟SOLIDCast程式
(2)檔案中"開始新模型"
(3)工具中的"ASCII STL to Binary"
(4)選取你要轉換的檔名(xxxx.stl)
(5)設定你想減少的三角形數量
(6)設一個新的檔案名稱(yyyy.stl)
(7)完成

Instructions for Modifying BOOT.INI To Allow Programs to Access Large Memory
This document describes a method for modification of the Boot.INI file in Windows XP. This applies ONLY to Windows XP and not to other Windows versions. These instructions must be followed VERY CAREFULLY. Failure to do so may cause your system to become unbootable.
Step 1 -- Back up your system Please begin by making a full backup of your computer.
Step 2 -- Become familiar with the Windows XP Recovery Console Before making this change to your Windows XP configuration, be sure you are familiar with running the Windows XP Recovery Console. Anytime you make changes to the configuration of your computer, there is a possibility of making a mistake that could cause problems booting your computer. The Windows Recovery Console can be used to repair these mistakes. We recommend you practice using the Windows Recovery Console before beginning this procedure. For more information about the Windows Recovery Console, refer to: Using Recovery Console, Microsoft TechNet. Recovery Console, The Elder Geek. Windows 2000 / XP Recovery Console, World of Windows Networking.
Step 3 – Install Hot Fix for Windows XP Service Pack 1 (SP1) ONLY
If your XP system is using Service Pack 1, you may experience problems rebooting your machine after making the change described in Step 4 below unless you do one of the following:
1. Download and install Service Pack 2 from the Microsoft website before making the change in
Step 4 below, or
2. If you are using Service Pack 1 and you do not wish to upgrade to Service Pack 2, then you should install the hot fix contained in the file WindowsXP-KB328269-x86-ENU.EXE. This file is available from Finite Solutions (email Larry@finitesolutions.com, Dave@finitesolutions.com or Rob@finitesolutions.com to request this file). Failure to perform this step may cause your system to be unable to boot properly.
If your XP system is using Service Pack 2 you do NOT need to install the hot fix. Most new computers have XP Service Pack 2 already installed.
Step 4 -- Edit boot.ini to enable 3 GB addressing
Boot.INI it can be accessed through the System control panel.
Open Control Panel, then open the System panel.
On the "Advanced" Tab, click the "Settings" button in "Startup And Recovery". You should see the following panel:
To edit BOOT.INI manually, click the "Edit" button in "System startup", which will bring up Notepad with BOOT.INI in it. Add /3GB to the options on the command line which refers to Windows XP Professional. Be sure to include a space before the / character when you add this to the end of the existing line. On most systems this will appear similar to the following:
[boot loader]timeout=30default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS[operating systems]multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /3GB
DO NOT MAKE ANY OTHER CHANGES IN THE BOOT.INI FILE, OR YOUR SYSTEM MAY BECOME UNBOOTABLE.
Save the file, then close all windows.
Step 5 -- Increase the size of your paging file You should also increase the size of your paging file to at least 4096 MB (4 GB). It is necessary to increase the size of the your paging file beyond 3 GB because it is shared by all processes on your computer.
Use this method to set the swap file size:
1. Go the the Control Panel (from Windows Start menu). 2. Double-click the System item. 3. Select the Advanced tab on the System Properties dialog. 4. Click the Performance button. 5. Click the Change button on the Performance Options dialog. 6. Enter the value “4096” into both the Minimum Size and the Maximum Size text field and then press the “Set” button, followed by OK on all the dialogs:
Make sure that the Paging File Size in the white box above reads “4096 – 4096” before clicking OK.
Step 6 – Reboot the computer
Now reboot the computer. This should activate the “Large Address” feature in Windows XP.
Please double-check your changes to boot.ini before restarting your computer!
Step 7 – Be sure that you are using the latest version of FLOWCast
Go to the Download page of the website and download the latest SOLIDCast Update file. This contains the latest version of FLOWCast which has the 3GB option.
