I. Introduction
The processing parameters of the various processing methods of mastercam, including the realization of cutting parameters, are all set in the form of a dialog box, and only need to be filled in when using. Mastercam milling provides a total of 6 tool magazines in both metric and imperial systems. The basic tools are included in the tool magazine. When the machining parameters are set, the cutting parameters are automatically entered into the dialog box after calling the tool in the tool magazine. However, in actual use, we found that the cutting parameters such as the feed rate of each tool, the speed of the tool, the spindle speed and Other cutting parameters are not in line with the actual conditions of the existing tools in the workshop, and it does not reflect the tools owned by the tools in the shop tool magazine. Basically, each item must be set up during use. The following is a discussion of how to build a mastercam milling tool magazine to create a tool library for the shop floor.
Second, the basic structure and setting method of the tool library
1. Milling tool library structure and setting regulations
The tool magazine is composed of a tool library specification and a number of individual tool description segments. Each description segment consists of 9 rows. The tool is specified. The individual tool description segments are separated by an empty description segment. Each row will be described in detail below.
(1) Notes of the tool library Note Each line of the comment description starts with #, followed by a statement, including the date of creation of the tool library, setting method, meaning of each parameter, and so on. Such as #刀库 format monjan1414: 51:192002.
(2) The composition of the tool description segment The tool description segment consists of 9 lines. The first line starts with tool, indicating that the tool definition starts, the line number must be marked, and followed by "", separated by spaces. The result is: 1 - tool, the following lines are the same as the line. Line 2 describes the tool material. The system specifies the figures for the materials: 1 - hss, 2 - carbide, 3 - coatedcar, 4 - ceramic, 5 - borzon, 10 - unknown, set the application number Fill in. The third behavior annotates the tool. Line 4 specifies the tool name. Line 5 specifies the tool manufacturer. Line 6 specifies the tool chuck. Line 7 specifies the tool parameters. According to tool number, tool type, radius type, diameter, corner radius crad, thread head number thds, tool nose angle, radius correction, tool length correction, xy feed rate, z-axis feed rate, tool feed rate, spindle speed , the coolant, the number of the blade number specify the parameters of each tool, each parameter is separated by a space, 0 can be without a decimal point. Line 8 specifies the tool drilling and milling properties. Drilling properties include the following: cycle type cycle, first boring depth peck1, remaining cleavage depth peck2, safety clearance peckclr, cutting retraction chipbrk, dwell time dwell, shoulder angle shldrangle, thread path rootdia(tap), Pupil offset boreshift. Milling properties include the following: applicable cutting form cutable (roughing, finishing or both), roughing step rghx (specified as the percentage of tool diameter), roughing step rghz, finishing step finx, fine Machining step finz, tip angle tipdia, tool root diameter rootdia (thread milling cutter), tip angle thdangle. Line 9 specifies the chuck and tool geometry, the center hole diameter of the knife end pilota, the cutting edge length fltelen, the knife length oalen, the blade length shldrlen, the shank diameter arbordia, the chuck diameter hldrdia, the chuck length hldrlen, the spindle rotation direction spindleccw , speed sfm (line speed), cutting amount per blade fpt, ​​measuring method metric.
It must be noted that all tool settings must contain 9 lines and the "tool" header. If not, the content must be replaced by a space.
2. Milling tool library setting method
(1) The establishment of the basic tool library In the mill ools directory, the system has established the basic graphics of the common tools, we can use it to build the basic tool library.
1) Create a text file (*.txt) with Notepad, add the tool parameters to the file according to the specified format, and store the file in the c:mcam8mill ools directory. The naming rules for the file name are as specified, such as slider.txt.
2) Run mill8, click “nc Management†→ “Define Tool†→ “Data Library in the main menu, right click in the tool management dialog box that appears, click “Create tool library from text in the shortcut menu, Open the read dialog box, specify the text file slider.txt that you generated, press OK, the path dialog box of the specified saved tool library appears, and the name of the slider can be determined.
3) Save slider.txt and slider.tl8 to the c:mcam8mill ools directory (assuming the software is installed in the c:mcam8 directory).
4) Call the tool library when using.
(2) Custom tool creation 1) The half-section of the drawing tool is stored in the c:mcam8mill ools directory, and the length of the x-direction radius is plotted in 1 mm.
2) Click “nc Management†→ “Define Tool†→ “Current†in the main menu to open the tool management dialog box, right click “Create New Tool†in the shortcut menu, open the definition tool box and specify the diameter.
3) Click on the Custom button in the Tool Type tab.
4) Click the “Select†button in the “Parameter Label†to select the saved tool and save it.
5) If you want to save to the tool magazine, select "savetolibrary.
(3) Use effect When the actual machining is performed, the cutting mode can be selected according to the existing tools in the workshop, and the inapplicability of the nc program is eliminated. When the parameter setting of the tool path is performed, the parameters of the tool part have not been redefined, reducing the tool. The time of the parameter is set.
