Machinist Kalc Programs

GraphNCalc83 iPhone App I already have a bit of information on my site about the GraphNCalc83 iPhone App, but I wanted to elaborate on it a bit more in this post. As a machinist, I purchased this app to use on my iPhone, because I need to double-check my math and trigonometry fast when I’m working on a job. And my phone is always with me. It’s very similar to the TI83/TI84 calculator that I’m familiar with but cannot carry around with me. The developer, Earnest Brock, is always helpful if you have any questions. I found this to be a pleasant surprise. The program is available for a one-time fee of $5.99 in the iTunes App store, which is an amazing price for everything this calculator offers. This fee is well worth it as it is very handy for the numerous occasions that I need to use a calculator in my life. Watch on YouTube I provide videos about how to use this app for the Machinist programs I have created for use in the GraphNCalc83. However, you can find a few other videos on...

Machinist Tools Calculators A machinist is only as good as his tools and his precise measurements. Yes, gages, calipers, micrometers, and all of the other tools in your toolbox are necessary. However, other machinist tools are often overlooked. For instance, we have all heard the old English proverb "Measure twice and cut once." An older Russian proverb, by the way, states, "Measure seven times and cut once." So, after you - and possibly a few of your co-workers - have confirmed the measurements for a job, it's also a good idea to run the numbers through a machinist calculator. The calculator programs I create for the GraphNCalc83 App are great for that final check. These take a few days to program and a few days to test before I upload them for sale. The app is downloaded on my own iPhone so it is immediately available when I need to check my calculated measurements for a job.  I invite you to look through my site to find a calculator program you can use for th...

Coordinate Constants from Center: These are used for establishing coordinate hole locations from the center location of a bolt circle with equally spaced holes. The holes can be aligned to a reference point on a center-line or equally spaced on both sides of the centerline. To use these values, first, select the required number of holes for the bolt circle and choose the appropriate type of coordinate reference location (either on the centerline or between the holes). Then, multiply the diameter of the bolt circle by the constant values shown in the chart. (Be careful to notice the plus (+) and minus (-) value for each constant). The resulting answers represent the coordinate locations and directions of the holes from the "X" and "Y" center reference points for the specified diameter of the bolt circle.

TAPERS: Machinists often turn, plane, bore, and grind tapers on a variety of parts, therefore, it is important to be familiar with the common standard tapers—American National Standard, Brown and Sharpe, Morse, and milling-machine arbor and spindle. How to determine the taper per inch or percentage of taper from a sample piece of work is a common problem. A study of the data and the rules in this section will help you handle taper problems. Taper Calculations: A cylindrical taper is a piece of material that decreases in diameter in a cone shape. Proportions for tapers are often expressed as Taper per Foot (TPF), or Taper per Inch (TPI). Taper calculations are most often expressed in terms of the difference in diameter at the opposite ends of the taper and the length of the taper center axis. Contact me if you would like for me to email the full PDF with all of the taper calculations to you. You may also download the Tapers PDF. Thanks for visiting www. MachinistKalc.com today. The m...

Coordinate Constants from Outside: These are used for establishing coordinate hole locations from the outside of a bolt circle with equally spaced holes. The holes can be aligned to a reference point on a centerline or equally spaced on both sides of the centerline. To use these values, first, select the required number of holes for the bolt circle.  Next, choose the appropriate type of coordinate reference location (either on the centerline or between the holes).  Then, multiply the diameter of the bolt circle by the constant value shown in the chart.  The resulting answers represent the coordinate locations of the holes from the "X" and "Y" reference edges for the specified diameter of the bolt circle. The full PDF  can be downloaded and includes coordinate constants for 3 to 12 holes. Contact me if you prefer that I email this to you instead. Sample: Coordinate constants from outside for 4 holes Thanks for visiting  www.MachinistKalc.com  today. These t...
