What is WCS in Mastercam?
Work Coordinate System (WCS) is the active coordinate system in use by Mastercam at any given time. The WCS tells the software how your part is positioned or oriented in the machine. The WCS contains the orientation of the XYZ axis plus the location of the zero point (the origin).
What is CNC toolpath?
CNC Machining & The Need for Toolpath The word “Toolpath” is a CAD/CAM related term that is basically a series of coordinate locations that a cutting tool will follow in the machining process. Toolpath is traditionally divided into two categories: Roughing and Finishing.
What is a contour toolpath used for?
The contour toolpath can be used as a clean-up pass to remove scalloping from a vertical face left by a previous surface milling operation as a final cutout or to trace roads/paths shallows into a surface.
What is a check surface?
Get answers to all the important questions about how and when to use check surfaces vs. boundaries to control where your toolpath does and doesn’t go. What are check surfaces? These are used to trim away unwanted toolpath or to bump toolpath up and out of the way.
What is tool path generation?
Tool path gen- eration is the process to plan the cutter trajectory relative to. the part based on the part model, machining method and. tolerance requirement.
When selecting a contour edge in a 2D contour toolpath What does the red arrow represent?
7) Zoom in on the inner circle. The red arrow represents the direction and side of the contour that will be machined. Right now, you can see that the tool will move clockwise on the outside of the contour. You want the tool on the inside of this contour.
What is 2D contour?
2D Contour allows you to machine profiles. The machining area can be selected from Edges, Sketches or a Solid face. Typically a finishing operation, but Contour can be used to take multiple cuts.
What is 2D CNC milling?
Working in two dimensions (2D) means that you are cutting out a part with features that are all at the same depth. This is common for laser, hot-wire, water jet, and plasma cutting, along with engraving. The FlashCut CNC software’s DXF Import feature automates the creation of a tool path from a 2D DXF file.
What is a 2.5 D model?
A 2.5D model is a model that is created by arranging deformable billboards along the depth direction, and it can express appearance of the character between two viewpoints with considering depth information.
What is 2.5 axis CNC?
A 2.5D machine, also called a two-and-a-half-axis mill, possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time due to hardware or software limitations, or a machine that has a solenoid instead of a true, linear Z axis. …
What is 3D milling?
3D toolpaths are machining operations in which the tool moves dynamically in three directions (X, Y, and Z), but stays perpendicular to the machine bed. 3D toolpaths are great for machining complex or organic shapes, because they can follow the changing surfaces of these shapes.
What is contour in CNC?
Sophisticated CNC machines can move a tool along two or more axes at once. This movement allows a machine to perform contouring. Contour movements can produce curves, circles, and even cones, like those shapes in Figure 3.
What is pocket milling?
In pocket milling the material inside an arbitrarily closed boundary on a flat surface of a work piece is removed to a fixed depth. Generally flat bottom end mills are used for pocket milling. Firstly roughing operation is done to remove the bulk of material and then the pocket is finished by a finish end mill.
What is surface contouring milling?
Contour Milling/Profiling – Contour milling produces a continuous curve of various degrees. Contour milling requires extensive knowledge of complex programs and machinery to produce ultra-precise tolerances and angles.
What is a contour machinist?
[′kän‚tu̇r mə′shēn·iŋ] (mechanical engineering) Machining of an irregular surface.
What is face milling?
Face milling is a machining process in which the milling cutting is placed perpendicular to the workpiece. The milling cutting is essentially positioned “face down” towards the top of the workpiece.
What is contouring operation?
Contouring a part means creating a fine finish on an irregular or uneven surface. Dissimilar to finishing a flat or even part, cnc contouring involves the finishing of a rounded, curved, or otherwise uniquely shaped part.
What is NC contouring?
NC contouring is an example of Continuous path positioning. Option – 1. Explanation: The continuous path positioning takes in the NC contouring.
Which of the following is a benefit of CNC machines?
The accuracy of the CNC machine ensures consistent product quality. The process is more precise than manual machining and can be repeated in exactly the same manner over and over again. Increased production speed and increased efficiency.
What is a contour profile?
A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at equal height above sea level.
Why do Isolines never cross?
Contour lines never cross on a topographic map because each line represents the same elevation level of the land.
Why do we need to exaggerate the vertical scale?
Vertical exaggeration is necessary to interpret line of sight profiles, but must be considered before jumping to conclusions about trafficability up slopes. A true scale profile is only possible over short distances with very steep topography.
How is vertical exaggeration calculated?
To determine the amount of vertical exaggeration used to construct a profile, simply divide the real-world units on the horizontal axis by the real-world units on the vertical axis. If the vertical scale is one 1″=1000′ and the horizontal scale is 1″=2000′, the vertical exaggeration is 2x (2000’/1000′).
What is vertical scale?
Vertical scale is the ability to move a single instance to a more powerful machine. Vertical scaling is far more limited than horizontal scaling because there is a limit to the size of a single machine. Moving to more powerful instances can also be expensive as compared to adding many cheap instances.
How do you find vertical relief?
It is easily calculated by subtracting the lowest elevation from the highest elevation in an area. If a mountain, for example, has an elevation of 8,000 feet and an adjacent valley has an elevation of 3,000 feet, we would say the relief between the two is 5,000 feet.
What does a vertical profile show?
Vertical Profile. The vertical profile of a highway is made up of straight lines (grade lines) and curves, as shown in the following figure. The curves joining the grade lines are called vertical curves, and their function is to make a smooth transition from one grade to another.
What is vertical relief?
Relief (or local relief) refers specifically to the quantitative measurement of vertical elevation change in a landscape. It is the difference between maximum and minimum elevations within a given area, usually of limited extent.
How do you calculate local relief?
Local relief is calculated by finding the difference in height between two points, or the highest minus the lowest point between the two points. Work out the local relief if Point has a height of 734 and Point B has a height of 533.
What is local relief quizlet?
Local relief. The difference in elevation between the highest and lowest points in a specified location.
