G00 U.004 (The incremental X move is the depth of cut.
Once the M98 line is read by the control, it then switches to program #500 and repeats 100 times. M98 P500 L100 (The same L and or 2 digits format prior works like the mill too) G00 G98 X1.9641 Z.400 (Remember the G98 feed per min code) 004″ per pass in a lathe due to diametral value) M19 The programmed diameter has been adjusted to X1.9641 to allow for the corners of the. Here is an example of a Lathe Sub-program. 400 away from the front of the part and rapid to the calculated diameter: In the main program, rapid the tool into position about. The actual start diameter will be Ø1.9641” in this scenario (This can be calculated automatically when using our online program generator). Let’s say the Bore is Ø2.000, the keyway is. Notice how the “E” bore dimension is smaller than the “A” bore dimension? Diameter “E” allows for the width of the insert. The X diameter programmed start point value will need to be calculated to allow for the width of the insert. If the outside diameter is Ø3.000 you’ll need to touch it off to a negative three inches (Ø-3.000). You can get around this by bringing the tool below center and touching off on the OD of the part. Setting the X offset using the tool tip on the inside diameter can be difficult because the corners of the square insert touch before the center of the insert. Touch off the Z axis as normal on the front of the part. First position the tool in front of the part on the X & Z axis. This allows you to adjust the final cutting size with the X wear offset as normal. Since it is easier to set the offset in the lathe to the tip of the tool, you should create the program to cut using the tip of the insert. 001” (depth of cut) pass with a broaching tool, you will need to program the tool to shift. 002” offset on a lathe only moves the tool by. However, you will need to consider that the lathe is moving on a diametrical value in the X direction and is not one to one. The motion of the tool in the lathe is identical to the motion of the tool in the mill.

The Program Generator does the majority of the work for you. You can also try our patented CNC Broach Tools Program Generator. The examples below are probably the easiest to manipulate and require the least amount of typing. TIP: There are many ways to make the tool path. Now that the spindle is locked in position it’s time to start the cutting motion of the broach. The cutting motion of the Broaching tool.Īlways follow the KEYS TO USING CNC BROACH TOOLS for tips & tricks on setting up the broach tool and to learn the fundamentals of slotting, such as clearance reliefs, material clearances, etc. TIP: Make sure you change back to G99 after you are done broaching. To do this you must change the FEED units from G99 (inches per revolution) to G98 ( inches per minute). Now that the spindle has been stopped and oriented, we now need to set the feed-rate mode so we can feed while the spindle is off. Locking the spindle using the spindle brake can also be performed to increase positional accuracy. This can usually be done with an M19 or a C axis command. Once the spindle has stopped you’ll need to orientate your spindle. This can usually be done with an M05 command. The first thing you’ll need to do prior to broaching in a CNC lathe is to stop the spindle. This is generally performed by programming a M05. On a mill it means the tool will be stopped. On a lathe this means the part must be stopped from spinning. Prior to broaching you will need to stop the spindle from turning. Locking the tool or material from rotation. If your codes are machine specific you will be able to locate and use them following this platform. The purpose of the guide is not to give you the codes you need but the concept behind what it takes to program tool path.
MAZAK CNC M CODES CODE
TIP: The code examples used in the guide will be that of FANUC, and YASNAC (Haas). This guide will walk you through the basic steps of what it takes to get a CNC machine broaching your parts. Interpolation, canned cycles, feed modes, etc.CNC Lathe broaching and CNC mill broaching are great methods of completing the slotting process and avoiding the cost other expensive Broaching Systems. This is really nice so you don't have to worry about accidentally overwriting one.Īs far as the actual code otherwise, it's 90% the same as any other G code machine. The G53.5 is assigned per program instead of in a table like G54, so if you had 1000 programs there would be 1000 independent G53.5's associated with them. It works more or less the same as work offsets on other machines, you just teach your Z on the setup page. This is the "mazatrol work offset", which lets you use tool data and go back and forth between mazatrol and G code very easily. The biggest difference program/setup wise is most of the time on Mazaks we use G53.5 instead of G54-G59.
