Can someone give me some guidance on checking perpendicularity with something besides a CMM? IP: Logged |

We use a V-block and Indicator when we don't use the CMM. We usually only use the CMM when we are checking parts for PPAP. IP: Logged |

That's what we are using and putting a snug fitting pin in the ID of the gear and then running the indicator off the face. Are we on the right track? (Thanks!) IP: Logged |

Assuming that the form of the hole is good enough to provide a stable datum axis and the hole/pin fit has no obvious play to distort your measurement, you are on a very solid track in my opinion. IP: Logged |

Steven is correct about the pin and hole. I believe this method is superior to almost any other. Just make sure every compoment of MTE is calibrated. IP: Logged |

If the item being checked is a simple right angle, you can check it with an indi-square and an indicator of the necessary accuracy. Setup the object to be checked on a surface plate, and run the indicator (attached to the indi-square) up and down the surface you are checking. Any further questions on this method, email me at [email protected] IP: Logged |
