9.3 Pitch Error Compensation

Due to manufacturing error of machine tool, there is a certain error between

the actual position and the command position of machine tool axis. This

function can decrease the error of actual position and command position

through increasing or decreasing actual displacement of machine tool.

The laser interferometer can measure error between the actual position and

the command position of machine tool axis and generate error

compensation data file. The existing HNC-8D-TU system only supports

*.rtl file generated by Renishaw laser interferometer.

9.3.1 Generation Of Pitch Error Compensation Data File

Presently, the system supports direct import of error compensation data file

(*.rtl) generated by Renishaw laser interferometer only. When Renishaw

software generates the error compensation file, the error compensation

table should be set according to the following requirements (as shown

below).

 "Chart type" must select "Separate compensation";

 "Compensation type" must select "Absolute";

162

 "Compensation resolution" must be "1"um;

 "Conversion of plus and minus symbols (+/-)" must select

"Compensation value";

 "Reference point " must be "0";

 The "Compensation start point" is the machine coordinate position of

the compensation start point, it must be 0;

 The "Compensation end point" is the machine coordinate position of

the compensation end point;

 "Compensation interval" is the compensation interval and it must be a

positive value.

10.2 Grounding

Correct grounding is very important for electrical device and it is

aimed at:

 protecting workers from electric shock arising from abnormal

phenomena;

 Protect electronic devices from interference of the machine and

other electronic devices nearby, which may result in abnormal

operation of control device.

While installing machine tool, it must be reliably grounded and neutral

line in the power grid cannot be used as earth wire; otherwise, personal

injury or device damage may be caused and exceptional operation of

device may be caused.

167

10.3 Power Supply

Power of HNC-808Di-TU CNC device is supplied by the electrical

control cabinet of the machine tool. For power supply of machine tool,

please refer to installation manual of machine tool.

10.4 Dust Removal Of Filter Fan Screen

Fan is an important element for ventilation and heat dissipation of CNC

device. In order to prevent dust from entering the device from the fan,

filter screen is set at air inlet and air outlet.

Dust will gradually stop up the filter screen after long-term use and

consequently ventilation conditions will worse and even normal operation

of devices will be affected. Thus, the user should regularly clean all filter

screens. Generally, filter screen of fan should be cleaned every three

months and cleaning period should be reduced under poor conditions.

10.5 Use After Long-time Idle

If CNC device is used after left unused for a long time, remove dust and

dry it. Then, check connection and grounding, power on for a period of

time and ensure the system is faultless before restart.
