RSM: Introduction to Response Surface Methodology

[@amirsafari7140]

hi, I'm working on laser-assisted turning and currently experimenting with five parameters: depth of cut, feed rate, spindle speed, laser power, and laser angle (the distance between the laser spot and cutting edge). Initially, I opted for a face-centered central composite design. However, I've noticed that when the laser power is set to 0 (indicating the laser is off), the laser angle becomes irrelevant. I'm uncertain about the appropriate experimental design in this situation. Could you please suggest a method or name for this scenario, considering the disregard for laser angle when laser power is zero? Thank you for your insights!

Wouldn't this be an interaction between variables? Sorry if that doesn't directly help, but just trying to clarify. Hope you find a good approach.

I'd go for grey box modeling. RSM is usually best when modeling the relationsships is very difficult. Your machine has some very dependend relationships, such as depth of cut, feed rate and spindle speed all influencing the energy input into the workpiece. Spend some time to build a grey box with relationships and unknown parameters, then do classic parameter identification.

Thank you very much for this tutorial Rosane, I didn't know about this method before.

[@gustavodias8823]

Excellent explanation Rosane, thank you.

Hi, can someone help me? Can i still use RSM if i only have one factor ?

[@MayaNyirenda]

Where can i find the data?

[@josephdaquila2479]

Direction of steepest ascent is just the gradient, correct?

[@dan-ls4mq]

how do we get the resulting yield, or yhe percentage?

[@GabrielMachadodeFreitas]

it depends what u are looking for. For exemple, if you are looking for the optimation condition to cultive some bacteria, maybe, you will measure the UFC (colony forming unit) as the response. So you want to find the point when UFC is maximus, or i could look to the optimation condition to have bacterial spores, so i can put the response as the % of spores done when he look to the vegetative cells ( % spores formation = (spores/vegative cell)*100

How can you do blocking in experimental design in rstudio? And how do you calculate the block effects?

Hi Can anyone explain if in 3d graph we get one color surface, then what does it means, as red shows highest value, green minimum,

[@williamariasv.2741]

Yes

[@TeenageSweetiee95]

Thank you very much for this insight. Is the entire course availible somewhere online? The link in description is expired.

[@RosaneRech]

The links are working now

[@aji9040]

At last got some clarity from your video

[@niravvora7673]

Which tool we are use for the graphs

[@tomasmatias4109]

Apparently r programming language with rstudio and the rsm package

Hello Ma'am, Hope you are fine. I want to use this software for my article. but can you tell me how can I download it? Is it paid or free? please let me know more information about this software! Thank you for your time.

[@RosaneRech]

Tou can download both R and R Studio for free. www.rstudio.com/products/rstudio/ www.r-project.org/

[@mominzarinamdnajeeb8269]

Excellent explanation

[@adityasharma9625]

Hy ma'am your voice is v appealing

[@summayyafatima7296]

why does she sounds like Sofia vergara ......nice explanation though.
