I have a measuring machine that measures up to 1000mm in length, but my traceable standard is only 400mm long. When I calibrate I align the standard parallel , start at the left side and measure every 10mm to check for accuracy deviations. I then move the scale to the right, overlapping approx...
In the "Requirements of Interval Measurements Test" in IEC 60601-2-25. The table 201.104 contains PQ-interval measurement. However, In the Reference measurement values of individual CAL waveforms. The PQ-interval is absent and PR interval has been provided.
Is it a typo error in...
Got a gear report from a customer showing profile and lead(report attached).
Its AGMA 2000, on the result sheet its showing Vphi(profile & Vpsi)Lead.
Is this Total profile(Fa) & Lead(Fb). Not seen this before, any help appreciated.
Thanks for all future help with this question.
I have a Romer Arm and I am using Polyworks as my inspection software.
The problem I am getting is after I scan the entire part and start to get my dimensions...
I got my Profile of a Surface of 1 edge...And it is at about 3mm.
I then got...
This is my first post on Elsmar so please bare with me.
I am measuring a part using my Romer Arm and Polyworks.
The problem I am getting is the the X dimension is in tolerance (Basic), the Y dimension is in tolerance (Basic), but then the true position is 14mm out of tolerance.
Good afternoon, I have a question that may be a bit silly.
Can a mill (machining operation) be used to (1) make a part and (2) inspect / certify the part?
I am not as familiar with the whole machining and V&V discussion, but I'm used to the "make a part on machine X and test the part...
Tell me please, what methods of reducing / eliminating the systematic component of error of measuring instruments.
As I know, some of them - the use of feedback (inverse transformation), exemplary measures (exemplary signals). Can someone already use these methods when...
I have seen a lot of times the terms "GAP and FLUSH" in GD&T drawings, but I have been looking for that terminology in the ASME Y14.5 Standard and I have not found anything.
Do you know what is the meaning of these two terms?
Thanks in advance,
Just a basic question. What is the difference between Monitor and Measure ? We regularly use terms like monitoring & measurement of processe, monitoring frequency, measuring frequency etc..
What is the best example to understand the basic difference between these terms?
I am struggling finding answers to my concern with Tape Measures. I learned that if a Tape Measure is used to verify parts it needs to be calibrated. So far so good...
Now, on the other hand I learned that a Measurement system should be 10x more accurate than the print states.
Currently, I am working on a problem that involves my machine shop not forming metal corners within tolerance. I've been looking for a radius gauge that will measure between 2" and 8". I have found some that start at 2.5" but, my measurements start around 2.6" +/- .050 and go to 7" +/- 0.050...
I have a question that is just killing me. hopefully you guys can help me.
I have a bent tube and my Datums A and B are both cylinders. they are one at the end of the pipe, and one at the other end of the pipe.
I can not figure out wich of these axes creates a plane and in what direction. I...
I'm looking for opinions on the "best" CMM for high accuracy machining. I have features with tolerances of .010mm to as small as .005mm. GD&T, complex geometry, medium size 140mm long x 75mm diameter to small 6mm long x 2.5mm diameter.
I have a controlled and fairly stable 24 hr temperature...
I work with metal stamped and formed parts. I am having trouble measuring a radius which is untrue. I'm tracing the radius with our vision system. I can measure it 10 times and get 10 different readings depending where I start and end my points. Any suggestions?
I would appreciate any help...
I've not yet had time to complete a gap analysis for transition to IATF from TS - I am transitioning summer 2018.
Someone from management asked me today about a "rumor" they heard. The rumor was that any/all measurements taken with a variable gage have to be recorded 100% once we are under the...
We have a measurement on powder particle size proportion using a set of sieves and an electronic scale. During measurement, the powder is sieve to obtain particles of certain sizes and use a scale to weight how much powder is left in the different sieves.
Question: to perform a GRR...
