Abstract(J)近年のマシニング加工において工具の軌道や加工方法を記述したNCコードの重要性は増してきている。本研究ではミリングやドリルによる加工を物理的にモデル化することによりNCツールパスの切削負荷解析を実施した。このモデルを使用した解析により加工品質を損なわずに加工時間を削減することが可能となった。

Translation

Abstract(E)Manufacturing of components recently entails development of complicated tool paths containing thousands of lines of code and dozens of tool changes for milling and drilling operations. Achieving meaningful reduction of cycle time while maintaining part quality is predicated upon the ability to model the physics of the machining operations. Forces and temperatures are predicted over the entire tool path using analytical and numerical techniques to extend an empirical database to generalized cutting conditions. Using this model, a method to achieve tangible reduction in cycle time without affecting part quality is presented.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
