Question 1. the roughness ra on what depends:
1 from tool geometry
2 from cutting speed
3 from progress
4 from recording angles
5 from tool material

for me are true the first 4... but I'm not sure... What do you think?



Question 2. the post processor, in a cn:
1 is the programming language iso for cn machine tools
2 is used to transform the part program into the clf
3 serves to write the clf
4 is used to transform a clf into a part program
5 is a specific software of each cn

for me is the 2


Question 3. the gxx instructions:
1 define only movements with removal of truciole
2 can define work movements
3 may be replaced by mxx instructions
4 must be followed by the coordinates of the arrival and departure point
5 with xx=01 represent movements in approach

for me is 2.

who helps me correct or tell me if I did well??? Thank you in advance.. .

in the first I think you did well
in the second but I think it is true also the 5(I believe only)
in the third I would have said true at 2 sure, 5 can be true because when you approach the piece you pass from g00 to g01.

It counts that they are arguments I've faced years ago so I'm not completely sure.
 
post processor is an interface system between cam software and numerical control machines. So I excluded the 5 because I think it's not a software. .
I don't know

while code g01 means linear interpolation.
Can this be a movement of approach?

Linear interpolation slow speed, while the g00 is linear interpolation high speed, usually work in speed advance g01 therefore close to the piece usually uses g01.

for the post processor I do not remember very much only that it is within each cnc to make the translation of the program in the language of the cnc (at least I think).. I don't remember
 
hi ornitorinco,
but are you sure that more answers were allowed?

However, with regard to roughness, who influences is progress.

Okay. Can't you tell me anything about pierarg? you are an engineer:)

I'm sorry to disappoint you but at the course of mechanical technology we studied cnc only in general lines.

Unfortunately, not in all universities, the subject is dealt with in an exhaustive manner (including mine) because it is not considered a characteristic subject.

I must admit that, unless you work as a cnc programmer/maintenancer, you will hardly have to deal with the instructions.

Good morning to all

I can answer the following questions:

Question 2. the post processor, in a cn:
4 is used to transform a clf into a part program
a clf file is a typical intermediate file of a cam software, generally not ascii, useful for fast changes and optimizations
when through the various controls, that the cam module makes available, you reach the goal the file is post-processed in the readable format from m.u. (fidia, selca ect ect)

Question 3. the gxx instructions:
2 can define work movements
because in addition to defining linear and circular work movements can also define other functions (eg g51 defines a new origin)

I hope I've been helpful
greetings
 
for the question about the part program so I was wrong to insert the 2 as correct then?
 
Unfortunately, I think so.
by the way greet me our beautiful region (I was born near gallipoli and I miss the puglia)

bye
 
I write here another doubt without opening other posts.. according to you the length of the cutting board depends on the material of the cutting board itself?
because it certainly comes from the cutting speed.... but from the material?
