<p>The rotation speed and rotation direction of a stirring blade are associated with the angle and direction of rotation operation of a shuttle dial (31d) rotatable in the left-right directions. In setting an operation program, a control section (30) causes the stirring blade to rotate by controlling a motor (18) in real time so that the motor (18) is associated with the amount of rotation operation and rotation direction of the shuttle dial (31d). A worker performs kneading work by actually using an investment material and operating the shuttle dial (31d), and while visually confirming conditions of the kneading, the worker adjusts the operation of the shuttle dial (31d) to set a parameter that forms the operation program. The parameter is stored in a course program storage section (34) in a manner associated with a course. When the worker presses a start key (31a) after selecting a course by a course selection key (31c), an operation program corresponding to the selected course is read and the stirring blade rotates according to the operation program. Thus, an operation program can be easily set.</p> |
