You can program the radius on a CNC lathe in various ways. One way is to use G-code. The following example shows how to program a radius using G-code:
This code will start the spindle turning at 500 RPM and move the tool 100 mm from the origin. The M06 command will then cause the tool to radius the workpiece at the current position.
Another way to program a radius on a CNC lathe is by using offsets. The following example shows how to use offsets to program a radius:
This code will create an offset of 100 mm from the origin in the X and Y directions. The O100 command will then cause the tool to radius the workpiece at the current position.
You can use these methods to program a radius on a CNC lathe. Which method you use depends on your preferences and what works best for your project.
How do you draw a radius in a CNC program?
- To program a radius on a CNC lathe, you need to know how to work with the machine’s control system. Choose to use the program editor or the G Code Editor. The G Code editor performs better and is easy to operate. It allows you to create any motion with your program.
- Place a single block and move to the positive (-) direction of the Z-axis Chamfer C.
- Move the block to the Z-axis.
- Place a single block, move the X-axis in the positive (-) direction Chamfer C.
- Place a single block and move to the positive (+) direction of the X-axis, and round corner R.
- Place a single section, move to the negative (-) direction of the Z-axis, round corner R.
- Move the block to the Z-axis direction.
- Place a single section and move to the positive (+) direction of the X-axis.
- Place a single block, move to the negative (-) direction of the X-axis, C and R usually specify a radius value.

- G03 code
CNC radius formula
The rounded corner radius is the distance from the inside corner of the framing square to where the glass touches the edge of the framing square.
How to program a radius into an angle
To program a radius on a CNC lathe, you need to know how to work with the ±1° (because the travel distance obtained by this calculation is large.
What is G03 in CNC?
Get the clockwise direction by viewing the arc from the positive side of a vector normal to the arc plane. G03 refers to the counterclockwise arc motion at feedrate. Just like the G01 command, G02 and G03 require a feed rate (F) as well as destination (or distance) coordinates (X, Y, and Z). The feed rate will default to the current feed rate when commanded previously in the program. The X, Y, and Z can be omitted for full circles.
How do you calculate circular interpolation?
F1 = ipt x nt x rpm is how you calculate circular interpolation. It consists of a cutter rotating about its axis while traveling in an orbiting motion about an ID or OD workpiece circumference without vertical shift during the operation.
How do you calculate chamfer length?
The starting point length of the chamfering Z=0, where tan60° is found by the maths table G1 X30 Z-1.5 F0.15. The chamfering point diameter X= Φ; G1 Z-50 and the length of chamfering point Z= -a. Calculate the formula of inner circle chamfer angle.
How do you write a radius in G-code?
You write it as 0179 R0. 1202 F26 and the “R” (radius) format for the arcs. There is a Z coordinate to specify a depth change for the endpoint of each arc, and this code uses relative motion (G91), so each “Z0.
What is radius programming?
Radius programming does not work when specified in the circle center point (with I, J, and K). The value following the character R is interpreted as the radius in [mm, inch], used in lines with circular programming.
How do you find the radius of a circle in C?
The radius of a circle is the distance from the center to any point on its circumference. The easiest way to find the radius is by dividing the diameter in half. If you do not know the diameter but know other measurements, such as the circle’s circumference or area, you can still find the radius. You can find it by using the formulas and isolating the variable.
How do you find the radius of a circle in C++?
- Find the area and circumference of the circle.
- Input the radius(1/2 of diameter) of a circle.
- Calculate the area of the circle and the circumference of the circle.
How do you program a CNC lathe ball?
Take a 1.25″diameter rod and cut a ball. Cut on the end, and the shaft has to be down to .25inches. You might have a fine drawing, but you might have a problem or two in real-world execution. It would be best to do most of the cutting with the tailstock in place and a finish pass or two to clean up after moving it out of the way.
How do you program a CNC lathe chamfer?
Yes, if you are using G code, you can lengthen your chamfer by changing its start point in X and its endpoint in Z., The start point for a 45-degree chamfer, will always be double the endpoint in Z subtracted from the endpoint in X.
How do you program a chamfer on a CNC machine?
The linear movement programmed with G01 G Code can be linked to the direction of the next CNC program block by a chamfer (C) or a radius (R).
How is chamfer depth calculated?
Spot drill chamfering a hole. A spot drill has a 90-degree point angle, making it easy to calculate the depth of a hole to be spot-drilled. Divide the diameter of the spot-drilled hole. For example, if using a 3/8-in spot drill to leave a 0.025 chamfer on a 0.25-in hole, the calculated depth would be 0.150 = 0.250/2 + 0.025.
How do you make a 45-degree chamfer on a lathe?
The setup for the lathe is to have the compound slide set to 45 degrees and the tool post square to the spindle axis. The cutting edge is flat, so you get a true surface.
How do you write a chamfer?
- Insert chamfer dimensions into a drawing.
- Click chamfer dimension tool chamfer dimensions relations on the dimensions/relations toolbar or click Tools > Dimensions > Chamfer.
- The pointer changes to pointer chamfer are dim.
- Select the chamfered edge, select one of the lead-in edges, then click in the graphics area to place the dimension. Select the chamfered edge first. The dimension does not appear until you select one of the lead-in edges.
- Use rapid dimensioning to place evenly spaced dimensions. Move the pointer outside of the dimension selector to place the dimension.
- The Dimension PropertyManager appears, and the tool remains active for you to dimension other chamfers.
- Click PM the OK.
What is CNC machine programming?
Computer numerically controlled manufacturers use (CNC) programming to instruct machines in producing parts. CNC programming creates program instructions for computers to control a machine tool. CNC is involved in the manufacturing process and improves automation and flexibility.
