请问：有搞齿轮三座标检测的吗？

CMM主要用于检测常规要素,如果测量齿轮等齿形误差,其检测精度很高,常规CMM既需要软件功能的加强,同时测量精度是不能达到要求的

回覆各位樓主：
(1) 齒輪量測
由於我們使用plastic gear，一般此類齒輪射出成型後的精度不會高於AGMA Q8。而我們標示齒輪也大多使用AGMA Q6或Q7。
量測時我們是使用投影法及圓棒量測。
相關資我可由下面得到(但我也一直沒有找到下列資料)

#AGMA 909-A06, Specifications for Molded Plastic Gears

The objective of this information sheet is to inform the plastic gear designer of the importance to clearly and thoroughly define the gear specifications to the plastic gear producer. It discusses the specifications for gear tooth geometry, inspection, other gear features and manufacturing considerations for involute external and internal spur and helical gears. Suggested data forms are provided in the annexes.

#01FTM09 - New Opportunities with Molded Gears
Unique tooth geometry that might be difficult or even impossible to achieve with cut gears can be applied to molded gears. This paper will investigate two types of gears that have been designed, molded and tested in plastic. The first is an asymmetric mesh with dissimilar 23 and 35 degree pressure angles. The second is an orbiting transmission with a 65 degree pressure angle. Both transmissions have higher load potential than traditional design approaches.

#ANSI/AGMA 1006-A97 (R2003) - Tooth Proportions for Plastic Gears
Presents a new basic rack, AGMA PT, which, with its full round fillet, may be preferred in many applications of gears made from plastic materials. It contains a description, with equations and sample calculations, of how the proportions of a spur or helical gear may be derived from the design tooth thickness and the basic rack data. In several annexes, there are discussions of possible variations from the basic rack and also a procedure for defining tooth proportions without using the basic rack concept.

(2) 齒輪以外的量測(即一般工作量測)
目前我們公司已導入GD&T (Y14.5M 1994)，然再配合離線(off-line)模擬量測軟体先寫好離線模擬自動化(這當然要配合3D工作圖)。然後再配合三次元座標量測(CMM)。
這可以省掉很多COST -- 如人、時間。
一般使用離線軟体如下

大致可分為

(I) CAT 1000 (From Mitutoyo) --  我們公司是使用這套
但我覺得非常不好用，不夠friendly。且還有很多bug(主因是德國mitutoyo則設計出來這套)

(II) CHECKMATE(FROM ORIGIN) -- 很多國際在用如H?、DE?L
好用，易上手且可以配合AUTOCAD及其他相關3D軟件
但這套軟体很難找到

(III) POWERINSPECT(FROM Delcam)
這套我也找不到


以上我的經驗，當然還有更深入。如不同平台CMM主機要溝通或共同一隻自動化量測程式時，這就需要DMIS語言。

对于大的内齿用三坐标检测好些吧。
