If you chain a point it will drill towards center line. You need to chain a circle so it will rotate the spindle to the correct plane and drill what you are looking for. A circle always lays in a flat plane so this is how mastercam knows to rotate to a plane and shift up or down in Y.

Well seeing how those holes would require a Y-Axis capable machine and not a C-axis yes I could see where it would not do what you expect since it is not possible to machine those features on a C-axis machine. They would need to be machined using a Mill-Toolpath and make sure the correct place is used for the view you want to machine it in.

Well I got it to work. I would have thought it would not do it that way, but sure enough even with a C axis Machine it does it. Here is the sample file hopefully the HLE version will open.

hi millman, it is actually a mastercam7 training book from in house solutions. yeah i agree the milling works just fine, and i would and could choose that, it was just the book said one thing so i was beating myself up trying to figure out why it wouldnt work. thanks again for the help

***EDIT*** i can successfully mill those holes, but the tutorial book says to drill them using cross drilling, im just wondering if im not choosing the right options.

The term hardened steel is often used for a medium or high carbon steel that has been given heat treatment and then quenching followed by tempering. The quenching results in the formation of metastable martensite, the fraction of which is reduced to the desired amount during tempering. This is the most common state for finished articles such as tools and machine parts. In contrast, the same steel composition in annealed state is softer, as required for forming and machining.

HI, thanks for the input. however im confused. im following tutorial #8 in the book and it says to choose those options. The cross drill should take that. Is it because my post cannot handle that? Sorry if im not getting it

Frequently, the term "hardening" is associated with tempered steel. Both processes are used hand in hand when hardening steel. The two part process begins with hardening the steel so that it becomes hard and does not wear over time. However, very often, this process leaves the steel very brittle and susceptible to breaking during use. Tempering reduces the hardness of the forged steel very slightly but improves the overall product as it results in steel that is much less brittle.

Hey guys, i am learning to program on our Haas Lathe with live tooling. When drilling a set of holes, as shown in the screen capture, my drill is not coming in on a perpendicuar path to the holes. The drill is tilted at an angle and im not sure exactly why?Basically the drill is not drilling straight. Any suggestions would be most appriciated. i know that cross drill is used for holes that are above or below the center line so it cant be that im using the wrong toolpath.

Almost always better to create arc and use the wireframe instead. I have seen Tool plane issues related to solid geometry, had to work through QC on that one

The two major processes of hardening and tempering can be broken down into four major steps. First, a piece of carbon steel is heated gradually until it reaches a temperature above the alloy's critical temperature. The steel is then quenched, usually in water or oil (though other quenches, such as brine or sodium hydroxide solutions, are sometimes used to achieve a particular result). The steel is now at that given alloy's maximum hardness, but as stated above, also brittle. At this point, tempering is usually performed to achieve a more useful balance of hardness and toughness. The steel is gradually heated until the desired temper colours are drawn, generally at a temperature significantly lower than the alloy's critical temperature. Different colours in the temper spectrum reflect different balances of hardness to toughness, so different temper levels are appropriate for different applications. The steel is then re-quenched to 'fix' the temper at the desired level. A talented smith or metalworker can fine-tune the performance of a steel tool or item to precisely what is required based solely on careful observation of temper colours. A visual representation of this process may make the concept easier to understand.

Cross drill is an options, but I would think you would be limited to hole on the plane you started with and not around the part like you have chosen. Those types of holes need to be off center and that is where the Y axis capabilities or mill toolpath would be the better choice a toolpath IMHO. I have not idea what workbook you are talking about. I recommend you email them and ask them to provide you a sample file to help you get a better understanding of what is being taught to you.

Okay. Well books are great to learn from, but do not trap yourself to the idea that it has to be by the book. Thing about making parts is the creativity of the person making the program. Let the art of making the part come through in your work. Great you are learning I applaud you for learning. I would not approach a part like what and if they got it to work like that I would love to see the step by step so I could learn how to take something I see as not possible to be possible. My understanding of C-Axis Toolpaths is they must be machinable with C axis capabilities. Those features to me are not and that is where I cannot wrap my brain around what you have told me you were instructed to do.

It is not easy to determine if steel has undergone the hardening and tempering process by simply looking at it, but there is a reliable and simple test.[1] To examine a piece of steel, obtain a hand file and file an edge of the selected metal. If the piece of steel has not undergone the hardening process, the metal file should easily 'bite' into the sample. If the metal has been hardened, the file fails to cut into the sample and glances off with little visible effect.

Depending on the temperature and composition of the steel, it can be hardened or softened. To make steel harder, it must be heated to very high temperatures. The final result of exactly how hard the steel becomes depends on the amount of carbon present in the metal. Only steel that is high in carbon can be hardened and tempered. If a metal does not contain the necessary quantity of carbon, then its crystalline structure cannot be broken, and therefore the physical makeup of the steel cannot be altered.
