Tutorial 7Configuring databases

Configuring the databases involve,• Adding a new Tool manufacturer in the database.• Adding a tool to a tool manufacturer.• Adding a tool material.• Adding cutting parameters.

Here, you will configure the database for each functions mentioned above.

CAPSturn is shipped with a master database file turn.MDB in which all the tool manufacturer database, tools and cutting parameters, tooland workpiece materials, machine list are stored. This file is stored in the directory in which CAPSturn is installed.

Configuring databasesCreating a new tool manufacturer

Whenever you create a new tool manufacturer it gets stored in turn.mdb file. You can either create a blank tool manufacturer in which caseyou will have to enter all the tools, tool materials and cutting parameters right from scratch. Building a tool manufacturer this way consumesa lot of time.Hence, the easier and efficient method would be to create a new manufacturer and copy the data from an existing manufacturer into it. Thisway you will only have to modify the names of tools, leaving the cutting parameters and tool materials unaltered.

• Select Config {bmc arrow.bmp} Tool and FS database from the Main menu.• At the prompt for password, enter cadem.• Click on Tool Manufacturer button.• A list of existing tool manufacturers appears. Click on the Add button.• Against the prompt Manufacturer name, enter First manufacturer – MM. Note: This is the name which will appear in the list of

manufacturers.• Select the units as MM.• Specify the remarks as New tool manufacturer included during training session.

So far you have specified all the details to create a new manufacturer. But as explained earlier, you need to copy the data from an existingmanufacturer into this new manufacturer. To do this,

• Check Copy data from an existing manufacturer?• Against the prompt Manufacturer to copy select General – MM from the list. All the data from General – MM manufacturer will be

copied into this manufacturer.• Click on the OK button.

Note: The process of copying data from an existing manufacturer may take some time depending on the amount of data in the selectedmanufacturer.

Notice that the new tool manufacturer First manufacturer – MM is created in the list of manufacturers. Select the manufacturer and click onTools button. Note that the tools available in this manufacturer are similar to that of General – MM manufacturer.

• Click on the OK button to exit this dialog box.

Configuring databasesAdding a tool type in a tool manufacturer

Before you add a tool type, you need to understand the concept of Tool class and Tool type in CAPSturn.

Tool classThese are the basic category of tools which are used to perform an operation. E.g., Drill, Turning tool, Boring tool, Grooving tool etc.

Tool type

These are various types of tools under a tool class. E.g., Twist drills, Insert drills, Flat drills are all different types of tools under Drill tool class.

Tool classes are fixed within CAPSturn, and cannot be added, modified or deleted. Tool types can be defined by you to put tools in separatecategories (types) and make selection easier. A tool type is specific to a Tool manufacturer.

To add a tool tpe,• Select the newly added tool manufacturer First manufacturer – MM from the Tool and FS database dialog box.• Click on the Tool types button. A dialog box with the list of existing tool types appear.• Click on the Add button.• Enter the name of tool type as New tool type against the prompt Tool type.• Against the prompt Tool class, select Drill from the list.• Enter the safe height as 3 MM.

Here, you have assigned the ‘New tool type’ to ‘Drill’ tool class. This means that New tool type belongs to the tool class drill and hence youcan select the tools from this tool type only when you select a Drill in the Machining menu.

• Click on the OK button. Notice that the tool type appears in the list.• Click on the OK button to exit Tool types dialog box.

Configuring databasesAdding a tool material in a tool manufacturer

Tutorial 8Customising the machines list

During installation, CAPSturn displays the available machine names and prompts you to select the required ones. When you click on amachine a brief explanation on its NC program format and it’s corresponding postprocessor file is displayed (Note: All the data required togenerate the NC program, Time study sheet etc. are stored in a postprocessor file). Select the machines which suit the program formatsthat you want. It’s corresponding postprocessor files are copied to the CAPSturn folder and the machines are added to the machines list.You can change the names of the machines later.

In this tutorial you will add a new machine to the machines list.

Adding a machine

To add a machine, you will first install a postprocessor file for the machine from the CD. To do this,

• Click on the Start menu of windows.

• Select Programs {bmc arrow.bmp} Cadem {bmc arrow.bmp} CAPSturn 7.0 – Add posts.• A dialog box appears with a list of available machines. Select the machine named Tutorial and click on the OK button.• A message appears indicating that the machine is installed. Click on the OK button.• Open CAPSturn and check the machines list. Notice that the machine Tutorial is added to the machines list.

You have installed a new machine to the list. Now you will change the name of the machine to identify it uniquely.

• Select Config {bmc arrow.bmp}Machines list from the Main menu. Enter the password as cadem.• Select the machine Tutorial. Click on the Modify button.• Change the machine name to New machine.• Leave the Folder for output files blank.

Notice that the postprocessor file is Tutorial. This is the file in which the mechanical parameters, NC program format etc. for the machineare stored. This file has an extension of .GPT.

• Click on the OK button.• Click on the OK button to exit machines list dialog box.• Click on Machines in the main menu. Notice that the machine name Tutorial is changed to New machine.• When you select this machine for generating the outputs, all the mechanical data and the NC program format is read from the

Configuring machine Data

Customising the machine data involves:Configuring machine's mechanical data. The mechanical data is used in,

NC program generation. Programmed spindle speeds and federates which exceed the machine's limits are clamped to thespecified limits.Generating the power graph. The available spindle power is displayed in the graph.Machining time estimation. The rapid traverse rate, axes and spindle acceleration/ deceleration times and execution times formiscellaneous functions are used.

• Configuring the NC program format. This consists of three sessions; Word format, Block format and Cycle format.Word format: Used to specify a code for a function and the format in which it should be output like with or without decimal etc.Block format: Used to specify the format for a block in the NC program like Tool change block, program start block etc.Cycle format: Used to enable or disable the cycles and specify the format in which the cycles should be output.

Building a postprocessor is a tedious process because you will need to specify the format for each and every parameter. Hence, it isalways recommended to modify an existing postprocessor and change the relevant parameters only. Here, you will open the postprocessorfile Tutorial.GPT and change some settings and parameters.

Machine mechanical data

• Select Config {bmc arrow.bmp} Postprocessor builder from the Main menu. Enter the password as cadem.• Select File {bmc arrow.bmp} Open and open the file Tutorial.GPT.• Click on Machine Data. In the dialog box, alter the following parameters leaving the remaining entries unchanged.

Machine name = Test machine Rapid traverse rate = 18000 Tool change time in seconds = 2

• Click on Feed rate and Spindle speed tab.Minimum feed rate = 0.01 0.0004Minimum spindle speed = 50

• Click on Miscellaneous functions tab. Select Program stop and click on the Modify button.• Enter the Function code as M02 and click on the OK button.• Select Tool change and click on the Modify button. Enter the Function code as M06 and Execution time in secs as 2. Click on the OK

button.• Click on History tab. Enter the following comment:
