    CNC Auto Parts Professional Manufacturer

    BMT is specializing in precision machining, non-standard parts processing, CNC bulk parts processing, numerical control car parts processing, batch titanium alloy in high precision parts processing, shaft parts processing, semiconductor equipment parts processing, etc, has the rich experience, equipped with CNC machining center, CNC lathes, wire cutting, milling machine, grinding machine, carved,  three coordinates measuring instrument, height measuring instrument and other high precision production and detection equipment.  



    1. Analyze the processing drawings and determine the processing process

    According to the processing drawings provided by the customer, the process personnel can analyze the shape, dimensional accuracy, surface roughness, workpiece material, blank type and heat treatment condition of the parts, and then select the machine tool, tool, determine the positioning clamping device, processing method, processing sequence and the size of the cutting dosage.  In the process of determining the machining process, the command function of the CNC machine tool should be fully considered, give full play to the efficiency of the machine tool, so that the processing route is reasonable, fewer knife times and short processing time.

    2. Calculate the coordinate value of the tool path path reasonably

    According to the geometric size of the machining part and the set programming coordinate system, the motion path of the center of the cutter route is calculated, and all the data of the cutter position are obtained.  General CNC system has the function of linear interpolation and circular interpolation, for relatively simple planar shape parts, such as parts of line and arc contour machining, only need to calculate the geometric elements of starting point and end point, the circular arc of circle (or the circular arc radius), two geometrical element intersection point or tangent point coordinate values.  If the nc system does not have the tool compensation function, the tool center trajectory coordinate value should be calculated.  For the parts with complex shape (such as the parts composed of non-circular curve and surface), it is necessary to use the straight line segment (or arc segment) to approximate the actual curve or surface, and calculate the coordinate value of its nodes according to the required machining accuracy. 


    3. Write CNC machining program for parts

    According to the parts of the knife route to calculate the tool path data and the process parameters have been determined and auxiliary action, programming personnel can be in accordance with the use of the NUMERICAL control system stipulated in the functional instructions and program format, section by section to write the parts of the processing program.  Attention should be paid to: first, the standardization of program writing should be easy to express and communicate;  Second, in the use of CNC machine tool performance and instructions on the basis of full familiarity, the instruction of the use of skills, programming skills.
