THREAD MILLING

Image
Hai dear friends,     Today I am sharing another useful programme which we can use for thread milling. Instead of making and using different programmes for different types of threads, we can use one single programme for all types of threading. Here we can use either multipoint threading tool or single pointed threading tool according to the availability of the tool. If we are using multipoint threading tools like tool in the image we have to give the value of " #8 = (THREAD STARTING FROM) " is the length of the insert.    MAIN PROGRAMME % O10 G0G90G40G80G54G15G69G17G49  M06T08H08 G91G28Z0M03S2000  #1=21.075(MAJOR DIA)  #2=14(TPI)  #3=18.26(ID)  #4=.1(DEPTH OF CUT) #5=150.0(FEED)  #6=2(NUMBER OF FINISHING PASSES)  #7=50.0(FEED OF LAST PASS)  #8=14.2(THREAD STARTING FROM) #9=.8(*J*)  (it is the gap between the tool tip and the hole minimum dia/2 or in other words the the                         distance from the tool tip to the side of

TAPER THREAD MILLING

Image
Hai everybody here I like to share a very useful macro programme for taper thread milling programme  by using single point tool. when we want to make a nonstandard taper thread or we don't have specific threading tool by using this programme we can make the required thread with a lathe threading tool. This same programme we can use for straight threads like unc threads, unf thread, metric thread even for square thread or half round thread also. The only think what we want to take care is the insert what we uses in the tool whould be with the same shape of the thread (for an experienced operator or programmer can understand what I said).            MAIN PROGRAMME % O0010 G0G90G40G80G55G15G69G17G49 M06T22H22 G91G28Z0M03S2000 #1=21.05(THREAD MAJOR DIA) #3=18.75(BORE ID) #30=14(TPI) #4=.25(DEPTH OF CUT) #8=0.0(THREAD STARTING FROM) #7=15(THREAD ENDS AT) #9=.1(*J*) (it is the gap between the tool tip and the hole minimum dia/2 or in other words the t

ANTI CAVITATION TRIM CAGE CNC MACRO PROGRAMME

#anti_cavitation_trim #controlvalves #contol_valve_noise -cage #low_desibel_cage # Noise_Abatement_Cages #cnc_manufacturing #cnc #programming #macro_programming #fanuc #mitsubishi Here I like to share a very useful and successful cnc macro programme which we can use for the manufacturing such types of anti cavitation trim cages. This programme we can use in all types of machines which have fanuc, mitsubhishi, and similar type control system uses. In this programme the operator need to edit the values which comes after the "=" regarding with the specific drawing and don't change any values or arguments or any words in the subprogram. While after starting the programme first time, we can change the value of #30 from "0" to "1", and there by whenever we needed to stop the machine by means of power failure, machine maintenance, tool damage, shift handover and even in holidays also, when we will start t
