July was a busy month at MachinistKalc.com. First of all, I created a new GrafNCalc83 program - How to Calculate a Desired Chamfer Using a Center Drill.   All of my GrafNCalc83 programs are $1.35 individually. You can buy all 33 programs  that I offer for the GrafNCalc83 for only $25. That’s a savings of $19.55! View my Programs Page to see all 33 programs and smaller bulk offers. Please read my full disclaimer  about how to use these programs before purchasing. If you have any questions or testimonials that you would like to share, feel free to contact me . I also added two new machinist tips that I think you will find to be very helpful. The first one is Area & Measurement of Plane Geometric Figures . The other one is Coordinate Constants from Center . Visit my Tips Page to view all of my machinist tips. Thanks for visiting www.MachinistKalc.com  today.

DISCLAIMER HOW TO CALCULATE A DESIRED CHAMFER USING A CENTER DRILL: Is a program to calculate the depth of 60 Degrees. Center Drills to obtain a certain diameter needed. Center Drill sizes 0 - 7 are programmed. You will also get a PDF of the program. Use email account on your iPhone, open with GrafNCalc83. You should receive a message "Imported Successfully". Watch how this program works BUY NOW for $1.35 : Please provide the email account you use on your phone in the "Notes" section of your payment. Program will be emailed to you within 48 hours of purchase - usually in much less time. Thanks for visiting www.MachinistKalc.com today.

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. Download the full PDF, which includes coordinate constants from center for 3 to 12 holes. Contact me if you would like for me to email the full PDF to you instead.

When you buy 3 GrafNCalc83 Programs for $1.35 each during July 2021, just send a note with your Paypal payment to let me know which program you want free. All 3 purchases must be made from one email address to qualify. The free program will be emailed to the same email address as the 3 bought programs. Search through the Programs page for your choices. If you have any questions or wish to contact me via email with your information instead, feel free to do so.

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.
