You can drag items up and down the list to change their order or drag them inside / outside of groups. Everybody makes mistakes till they learn the programs. Pass Depth, Step Over, Feed Rate and Plunge Rate?? Hi The maximum depth of cut the tool can cut. 3/8" Dia. Plunge rate is the speed at which the router bit is driven down into the material when starting a cut and will vary depending on the bit used and the material being processed. Only draw the Right-hand side of the cutter geometry to the correct size and scale as shown in the image above. If we're deleting a group, this will delete all the tools inside it in the same way. Copy from a different (identical) tool from the same (or different material). My settings are feed rate at 80 and Plunge rate at 30 had no problems at all. Your screen grab for the V bit shows 100 ipm feed rate and 30 ipm plunge, those are the default, unchanged feedrates. This is the number of the tool needed to machine the job. Copied from the same tool, different material. The distance the cutter moves over when doing area clearance cutting. 10) Select Apply then OK. This can be used for when we know there is a more up-to-date version online. The diameter of the tool in either inches or mm. Pretty new to the whole cnc world, with just completing my first shapeoko 2 1000x1000mm machine. Dell optiplex 5070 hackintosh. The cutting rate at which the cutter is moved vertically into the material or during ramping moves. This is the height above the job at which it is safe for the cutter to move at rapid or maximum feed rate. Examples of these types of cutters and the kind of cuts they can be used for are shown in the images below: Before opening the tool database, draw to exact scale the Right side of the cutter geometry in the 2D Window Use the Node Editing tools to create the arcs and curves etc. More details on those will be given in the next sections. These values are defined for a particular material / machine. Oh yeah, I use Vcarve Pro. The Tool Database can be accessed from the Select... button through the various Toolpath forms. Changing the cutter tool type is equivalent to creating a new tool, so all existing data for that tool (if any) may not be applicable anymore. I don’t know VCarve, but most CAM software have a setting for safe hight. This set of parameters are defined to be per machine per material. You can not plunge an end mill into material like you would a drill bit. The problem I am having is working out the above settings for more complicated projects. Now I need to make a simple but effective dust boot… ha ha ha. If i increase the plunge rate will the bit pull up out of the cut faster to ensure that the bit is clear before the X and Y moves? Optimizing feed rates and speeds: 1. Normally plunge rate refers to the VERTICAL speed, which would result in a horizontal speed faster than the plunge rate, if done properly. Mercedes vedoc access. Plunge Rate: 20 inches/minute . I’ve grasped the concept of creating more or less basic projects, some snags along the way but I’m doing my thing.
