Application of SIEMENS Radius Parameter Value TC

Abstract : This paper combines the application of the SIEMENS R parameter program in the production process to illustrate how the $TC_DP6 can be used to give the tool radius compensation value in the program. Set the radius value to a variable value in R programming and then use the $TC_DP6 command to enter the changing radius value into the CNC memory. With this radius variable program, you can manually create some contour loop machining and regular surfaces that cannot be programmed.

introduction:

There are two ways to input the radius compensation value into the CNC memory in manual programming.

Â Â Â Method 1: Manually input the tool radius value to be used directly into the CNC memory. The radius value entered by this method is fixed.

Â Â Â Method 2: In the program, the corresponding radius value is input to the CNC memory by the instruction $TC_DP6. This input method can input the radius value to the memory arbitrarily during the program running, if the radius value is set by the R parameter program. For a variable, it corresponds to $TC_DP6. The contour of this program can be continuously changed. In manual programming, this programming is a flexible and powerful function, especially when it is used together with the macro program, it will show its function and convenience. In manual programming it is an irreplaceable use to solve some complex programming. The processing of regular curved surfaces such as contours.

Â Â Â In this paper, combined with the application of $TC_DP6 in actual production, the examples are given to illustrate the application of tool compensation value in manual programming.

First, Siemens (SIEMENS) tool radius compensation value $TC_DP6 description and use

Â Â Â In the SIEMENS CNC system, $TC_DP6 is a system value and its use is strictly regulated. Its format depends on the required tool compensator.

See the table,

address	meaning	Description	Instruction format
$TC_DP6[t,d]	Radius compensation value	Read or write the values â€‹â€‹of t and d	$TC_DP6[_,_]=R_

Description:

1, t: T tool number 1-32000, T0 has no tools (up to 32 tools are stored in the system at the same time)

2. d: Tool compensation number D. A tool can match several different compensation data sets from 1 to 9. If no D command is written, D1 will automatically take effect. If programmed to D0, the tool offset value is invalid.
