The Master Machinist-Machinist Software for finding Cutting Speeds,Tapdrills,Boltholes and More

So now you have arrived at this site,probably as a result of a search and you need to find out if it was worth your effort.

Short story: The Master Machinist was written by a working machinist based on tasks that I did every day.Things like finding the tap drill for a particular tap,asking questions like what is the actual dia of a number 45 drill or a letter W drill,how many millimetres are in 0.6282 inches, or vice versa.Since too much time was spent looking up charts and reference books I thought that it could be easily put on to the computer that was next to my machine.

Long story:The Master Machinist started as just a drill finder programme in the late 1990's and has evolved from there,mostly for personal use.If you've read this far you probably would like to know what The Master Machinist can actually do.

Some on the functions are:

Unit Conversions:- There are over 30 different conversions,all of which work both ways inches-millimetre,decimal degrees to degrees minute seconds,inches per foot to degrees minute seconds, hp to kw, deg F ot deg C to deg K,and many more.
Tap Drills:- Find tap drills for many different threads,either cut tap or forming tap,thread forms include UN,BSW,Metric,NPT,BSP and some thread inserts.You can also calculate the tap drill for odd sized threads .
Drill Finder:- Find the nearest drill to a particular size,metric or inch.Just enter the dia and The Master machinist will display the nearest size,the database contains both inch and mm drills so the result may be mm for and inch search or inch for a mm search.
Cutting Speeds and feeds:- Calculate the cutting feeds and speeds for a variety of materials and tools just by selecting the tool type and size and material.there is a option to set a maximum RPM,no sense in calculating a spindle speed beyond your machines ability.You can also input your own data and find speeds or feeds based on what you are actually using.The database can be easily edited.
Centre Drill Depth:- Calculate the depth required to chamfer to a specific dia using a specific centre drill.
Bolt Hole positions:- Calculate the X/Y co-ordinates for a bolt hole pattern,options include being able to find the pitch circle dia from the distance between the centre of to adjacent holes.
Polygon Dia:- Find the max dia of a bar for a regular polygon of any number if sides.Recalculate by changing the area a given percent. For instance if I have a hexagon with an area of 0.267 and I decrease it by 3.7% what is the size of the new hex across the flats.
Thread Measurements:- Calculate the dimensions of threads and the measurement of the PD using the three wire method.The thread database contains a large number of sizes,and if the size is not in the database you can calulate the basic dimensions by entering the dia and tpi,or pitch.calculate for 60 deg threads,55 deg threads and 29 deg threads.
Triangles:- Calculate the missing components of a right angle triangle by entering any two known values.Calculates the indvidual blocks of a stack for a 5 in Sine based on the result.
Material Weights:- Calculate the weight of a piece of material,select material,select form,square round hex tube,and then enter dimensions
GCode generator:- The Master Machinist will also generate GCode for simple square or round pockets,Just enter some basic data like pocket size and depth,end mill size ,feeds and rpm and clean up pass and depth and The Master Machinist will generate the code,with estimated cycle time.For simple pockets this is sometimes alot quicker and easier than doing it in your CAM programme.

The Master Machinist will do much much more. Download an evaluation copy and find out for yourself.The evaluation copy is full function but limited in the number of uses.
